Backport of http://review.gluster.org/16329
Issue:
In disperse volume, the file is present across bricks, hence the stat
from one brick doesn't carry the valid size of the file. Therefore
the upcall from one brick updating the md-cache results in wrong size
being updated.
Fix:
If the notification is cache invalidation then, indicate md-cache that
the attributes is invalid.

When we have cascading locks with same lk-owner there is a possibility for
a deadlock to happen. One example is as follows:
self-heal takes a lock in data-domain for big name with 256 chars of "aaaa...a"
and starts heal in a 3-way replication when brick-0 is offline and healing from
brick-1 to brick-2 is in progress. So this lock is active on brick-1 and
brick-2. Now brick-0 comes online and an operation wants to take full lock and
the lock is granted at brick-0 and it is waiting for lock on brick-1. As part
of entry healing it takes full locks on all the available bricks and then
proceeds with healing the entry. Now this lock will start waiting on brick-0
because some other operation already has a granted lock on it. This leads to a
deadlock. Operation is waiting for unlock on "aaaa..." by heal where as heal is
waiting for the operation to unlock on brick-0. Initially I thought this is
happening because healing is trying to take a lock on all the available bricks
instead of just the bricks that are participating in heal. But later realized
that same kind of deadlock can happen if a brick goes down after the heal
starts but comes back before it completes. So the essential problem is the
cascading locks with same lk-owner which were added for backward compatibility
with afr-v1 which can be safely removed now that versions with afr-v1 are
already EOL. This patch removes the compatibility with v1 which requires
cascading locks with same lk-owner.
In the next version we can make locking-scheme option a dummy and switch
completely to v2.

* Even on errors like ENOENT, AFR logs split-brain after
read-txn refresh, introduced by commit a07ddd8f.
This can be a cause of much panic and confusion and needs to be fixed.
* Also fixed this issue in write-txns.
* Fixed afr read txns to log about split-brain only after knowing that
there is no split-brain choice configured.
* Removed code duplication
* Fixed incorrect passing of error code in afr_write_txn_refresh_done()
(the function was passing -0 as errno to gf_msg().

Problem:
__afr_set_in_flight_sb_status(), which resets event_gen to zero, is
called if failed_subvols[i] is non-zero for any brick. But failed_subvols[i]
is true even if the brick was down *before* the transaction started.
Hence say if 1 brick is down in a replica-3, every writev that comes
will trigger an inode refresh because of this resetting, as seen from
the no. of FSTATs in the profile info in the BZ.
Fix:
Reset event gen only if the brick was previously a valid read child and
the FOP failed on it the first time.
Also `s/afr_inode_read_subvol_reset/afr_inode_event_gen_reset` because
the function only resets event gen and not the data/metadata readable.

Backport of: http://review.gluster.org/16286
PROBLEM:
Consider a volume with granular-entry-heal and sharding enabled. When
a replica is down and a shard is created as part of a write, the name
index is correctly created under indices/entry-changes/<dot-shard-gfid>.
Now when a read on the same region triggers another MKNOD, the fop
fails on the online bricks with EEXIST. By virtue of this being a
symmetric error, the failed_subvols[] array is reset to all zeroes.
Because of this, before post-op, the GF_XATTROP_ENTRY_OUT_KEY will be
set, causing the name index, which was created in the previous MKNOD
operation, to be wrongly deleted in THIS MKNOD operation.
FIX:
The ideal fix would have been for a transaction to delete the name
index ONLY if it knows it is the one that created the index in the first
place. This would involve gathering information as to whether THIS xattrop
created the index from individual bricks, aggregating their responses and
based on the various posisble combinations of responses, decide whether to
delete the index or not. This is rather complex. Simpler fix would be
for post-op to examine local->op_ret in the event of no failed_subvols
to figure out whether to delete the name index or not. This can occasionally
lead to creation of stale name indices but they won't be affecting the IO path
or mess with pending changelogs in any way and self-heal in its crawl of
"entry-changes" directory would take care to delete such indices.

Problem:
afr_replies_interpret() used the 'readable' matrix to trigger client
side heals after inode refresh. But for arbiter, readable is always
zero. So when `dd` is run with a data brick down, spurious data heals
are are triggered. These heals open an fd, causing eager lock to be
disabled (open fd count >1) in afr transactions, leading to extra FXATTROPS
Fix:
Use the accused matrix (derived from interpreting the afr pending
xattrs) to decide whether we can start heal or not.

Before http://review.gluster.org/#/c/15673/, after inode refresh, we
failed read txns in case of EIO or event_generation being zero. For
write transactions, the check was only for EIO. 15673 re-factored the
code to fail both read and write when event_generation=0. This seems to
have caused a regression as explained in the BZ.
This patch restores that behaviour in afr_txn_refresh_done().

Currently these are few events related to child_up/down:
GF_EVENT_CHILD_UP : Issued when any of the protocol client
connects.
GF_EVENT_CHILD_MODIFIED : Issued by afr/dht/ec
GF_EVENT_CHILD_DOWN : Issued when any of the protocol client
disconnects.
These events get modified at the dht/afr/ec layers. Here is a
brief on the same.
DHT:
- All the subvolumes reported once, and atleast one child came
up, then GF_EVENT_CHILD_UP is issued
- connect GF_EVENT_CHILD_UP is issued
- disconnect GF_EVENT_CHILD_MODIFIED is issued
- All the subvolumes disconnected, GF_EVENT_CHILD_DOWN is issued
AFR:
- First subvolume came up, then GF_EVENT_CHILD_UP is issued
- Subsequent subvolumes coming up, results in GF_EVENT_CHILD_MODIFIED
- Any of the subvolumes go down, then GF_EVENT_SOME_CHILD_DOWN is issued
- Last up subvolume goes down, then GF_EVENT_CHILD_DOWN is issued
Until the patch [1] introduced GF_EVENT_SOME_CHILD_UP,
GF_EVENT_CHILD_MODIFIED was issued by afr/dht when any of the subvolumes
go up or down.
Now with md-cache changes, there is a necessity to differentiate between
child up and down. Hence, introducing GF_EVENT_SOME_DESCENDENT_DOWN/UP and
getting rid of GF_EVENT_CHILD_MODIFIED.

of cache invalidation(upcall).
Issue:
------
When a cache invalidation is recieved as a result of changing
pending xattr, the read_subvol is reset. Consider the below chain
of execution:
CHILD_DOWN
...
afr_readv
...
afr_inode_refresh
...
afr_inode_read_subvol_reset <- as a result of pending xattr set by
some other client GF_EVENT_UPCALL will
be sent
afr_refresh_done -> this results in an EIO, as the read subvol was
reset by the end of the afr_inode_refresh
Solution:
---------
When GF_EVENT_UPCALL is recieved, instead of resetting read_subvol,
set a variable need_refresh in inode_ctx, the next time some one
starts a txn, along with event gen, need_rrefresh also needs to
be checked.

Problem:
Currently, I/O on a split-brained file fails even when the
favorite-child-policy is set until the self-heal is complete.
Fix:
If a valid 'source' is found using the set favorite-child-policy,inspect
and reset the afr pending xattrs on the 'sinks' (inside appropriate
locks),refresh the inode and then proceed with the read or write transaction.
The resetting itself happens in the self-heal code and hence can also
happen in the client side background-heal or by the shd's index-heal in
addition to the txn code path explained above. When it happens in via
heal, we also add checks in undo-pending to not reset the sink xattrs
again.

Incorrect initialisation of local->optimistic_change_log was leading
to skipped pre-op and post-op even when a brick didn't participate in
the txn because it was down.
The result - missing granular name index resulting in some entries
never getting healed.
FIX:
Initialise local->optimistic_change_log just before pre-op.
Also fixed granular entry heal to create the granular name index in
pre-op as opposed to post-op. This is to prevent loss of granular
information when during an entry txn, the good (src) brick goes
offline before the post-op is done. This would cause self-heal to
do conservative merge (since dirty xattr is the only information
available), which when granular-entry-heal is enabled, expects
granular indices, the lack of which can lead to loss of data in
the worst case.

Problem:
1) When a blocking lock is issued and the parallel lock phase fails
on all subvolumes with EAGAIN, it is not switching to serialized
locking phase.
2) When quorum is enabled and locks fail partially it is better
to give errno returned by brick rather than the default
quorum errno.
Fix:
Handled this error case and changed op_errno to reflect the actual
errno in case of quorum error.

Problems:
1) Inodelk is not taking quorum into account
2) finodelk, [f]entrylk are not implemented correctly
3) By default afr doesn't go for non-blocking parallel locks.
Fix:
Implemented a common framework which can be used by
[f]inodelk/[f]entrylk. Used quorum for the same.

Problem:
Consider a replica setup, where one mount writes data to a
file and the other mount reads the file. In afr, read operations
are not transaction based, a brick(read subvolume) is chosen as
a part of lookup or other operations, read is always wound only
to the read subvolume, even if there was write from a different client
that failed on this brick. This stale read continues until there is
a lookup or any write operation from the mount point. Currently, this
is not a major issue, as a lookup is issued before every read and it will
switch the read subvolume to a correct one. But with the plan of
increasing md-cache timeout to 600s, the stale read problem will be
more pronounced, i.e. stale read can continue for 600s(or more if cascaded
with readdirp), as there will be no lookups.
Solution:
Afr doesn't have any built-in solution for stale read(without affecting
the performance). The solution that came up, was to use upcall. When a file
on any brick is marked bad for the first time, upcall sends a notification
to all the clients that had recently accessed the file. The solution has
2 parts:
- Identifying when a file is marked bad, on any of the bricks,
for the first time
- Client side actions on recieving the notifications
Identifying when a file is marked bad on any of the bricks for the first time:
-----------------------------------------------------------------------------
The idea is to track xattrop in upcall. xattrop currently comes with 2 afr
xattrs - afr dirty bit and afr pending xattrs.
Dirty xattr is set to 1 before every write, and is unset if write succeeds.
In certain scenarios, dirty xattr can be 0 and still the file could be bad
copy. Hence do not track dirty xattr.
Pending xattr is set on the good copy, indicating the other bricks that have
bad copy. It is still not as simple as, notifying when any of the pending xattrs
change. It could lead to flood of notifcations, in case the other brick is
completely down or consistantly failing. Hence it is important to notify only
once, the first time a good copy is marked bad.
Client side actions on recieving pending xattr change, notification:
--------------------------------------------------------------------
md-cache will invalidate the cache of that file, so that further lookup is
passed down to afr and hence update the read subvolume. Invalidating only in
md-cache is not enough, consider the folling oder of opertaions:
- pending xattr invalidation - invalidate md-cache
- readdirp on the bad read subvolume - fill md-cache
- lookup (served from md-cache)
- read - wound to the old read subvol.
Hence, along with invalidating md-cache, it is very important to reset the
read subvolume for that file, in afr.

1. xattrop doesn't carry info saying post op/pre op.
2. Pre xattrop will have 0 value for all pending xattrs,
the cbk of pre xattrop carries the on-disk xattr value.
Non zero indicated healing is required.
3. Post xattrop will have non zero value for any of the
pending xattrs, if the fop failed on any of the bricks.

Currently ipc() is not implemented in afr. md-cache and upcall
uses ipc to register the list of xattrs, [1] for more details.
For the ipc op GF_IPC_TARGET_UPCALL, it has to be wound to all
the replica subvolumes. ipc() is failed when any of the
subvolumes fails with other than ENOTCONN or all of the subvolumes
are down.

Backport of: http://review.gluster.org/15929
When an afr data transaction is eligible for using
eager-lock, this information is represented in
local->transaction.eager_lock_on. However, if non-blocking
inodelk attempt (which is a full lock) fails, AFR falls back
to blocking locks which are range locks. At this point,
local->transaction.eager_lock[] per brick is reset but
local->transaction.eager_lock_on is still true.
When AFR decides to compound post-op and unlock, it is after
confirming that the transaction did not use eager lock (well,
except for a small bug where local->transaction.locks_acquired[]
is not considered).
But within afr_post_op_unlock_do(), afr again incorrectly sets
the lock range to full-lock based on local->transaction.eager_lock_on
value. This is a bug and can lead to deadlock since the locks acquired
were range locks and a full unlock is being sent leading to unlock failure
and thereby every other lock request (be it from SHD or other clients or
glfsheal) getting blocked forever and the user perceives a hang.
FIX:
Unconditionally rely on the range locks in inodelk object for unlocking
when using compounded post-op + unlock.
Big thanks to Pranith for helping with the debugging.

Raghavendra G found that posix is trying to print %s
but passing an int when HEALTH_CHECK fails in posix.
These are the kind of bugs that should be caught
at compilation itself.
Also fixed the problematic gf_event() callers.

On a sharded volume when a brick is replaced while IO is going on, named
lookup on individual shards as part of read/write was failing with
ENOENT on the replaced brick, and as a result AFR initiated name heal in
lookup callback. But since pargfid was empty (which is what this patch
attempts to fix), the resolution of the shards by protocol/server used
to fail and the following pattern of logs was seen:

In afr lookup when NULL dict is received in lookup, afr
is supposed to set all the xattrs it requires in a new dict
it creates, but for 'link-count' it is trying to set to the
dict that is passed in lookup which can be NULL sometimes.
This is leading to error logs. Fixed the same in this patch.

Problem:
Sharding exposed a bug in arbiter config. where `dd` throughput was
extremely slow. Shard xlator was sending a fxattrop to update the file
size immediately after a writev. Arbiter was incorrectly over-riding the
LLONGMAX-1 start offset (for metadata domain locks) for this fxattrop,
causing the inodelk to be taken on the data domain. And since the
preceeding writev hadn't released the lock (afr does a 'lazy'
unlock if write succeeds on all bricks), this degraded to a blocking
lock causing extra lock/unlock calls and delays.
Fix:
Modify flock.l_len and flock.l_start to take full locks only for data
transactions.

Problem: Currently heal info command prints all
the files/directories if the index for the
file/directory is present in .glusterfs/indices folder.
After implementing patch http://review.gluster.org/#/c/13733/
indices of the file which is going through update fop
will also be present in .glusterfs/indices even
if the fop is successful on all the brick. At this time
if heal info command is being used, it will also display this
file which is actually healthy and does not require any heal.
Solution: Take lock on a file corresponding to the indices
and inspect xattrs to decide if the file needs heal or not.

Problem:
In arbiter configuration, posix-xlator in the arbiter brick always sets
the GF_CONTENT_KEY in the response dict with a value 0. If the file size on
the data bricks is more than quick-read's max-file-size (64kb default),
those bricks don't set the key. Because of this difference in the no. of dict
elements, afr triggers metadata heal in lookup code path, in turn
leading to extra lookups+inodelks.
Fix:
Changed afr dict comparison logic to ignore all virtual xattrs and the
on-disk ones that we should not be healing.
Also removed is_virtual_xattr() function. The original callers to this
function (upcall) don't seem to need it anymore.

The command basically allows replace brick with src and
dst bricks as same.
Usage:
gluster v reset-brick <volname> <hostname:brick-path> start
This command kills the brick to be reset. Once this command is run,
admin can do other manual operations that they need to do,
like configuring some options for the brick. Once this is done,
resetting the brick can be continued with the following options.
gluster v reset-brick <vname> <hostname:brick> <hostname:brick> commit {force}
Does the job of resetting the brick. 'force' option should be used
when the brick already contains volinfo id.
Problem: On doing a disk-replacement of a brick in a replicate volume
the following 2 scenarios may occur :
a) there is a chance that reads are served from this replaced-disk brick,
which leads to empty reads. b) potential data loss if next writes succeed
only on replaced brick, and heal is done to other bricks from this one.
Solution: After disk-replacement, make sure that reset-brick command is
run for that brick so that pending markers are set for the brick and it
is not chosen as source for reads and heal. But, as of now replace-brick
for the same brick-path is not allowed. In order to fix the above
mentioned problem, same brick-path replace-brick is needed.
With this patch reset-brick commit {force} will be allowed even when
source and destination <hostname:brickpath> are identical as long as
1) destination brick is not alive
2) source and destination brick have the same brick uuid and path.
Also, the destination brick after replace-brick will use the same port
as the source brick.

Problem:
When tiering/rebalance does migrations and afr with 2-way replica is in
picture, migration can read stale data if the source brick goes down and writes
to the destination. After this deletion of the file leads to permanent loss of
data after migration.
Fix:
Rebalance/tiering should migrate only when the data is definitely not stale. So
introduce an option in afr called consistent-io which will be enabled in
migration daemons.

cyclic order
When the bricks are brought offline and then online in cyclic
order while writes are in progress on a file, thanks to inode
refresh in write txns, AFR will mostly fail the write attempt
when the only good copy is offline. However, there is still a
remote possibility that the file will run into split-brain if
the brick that has the lone good copy goes offline *after* the
inode refresh but *before* the write txn completes (I call it
in-flight split-brain in the patch for ease of reference),
requiring intervention from admin to resolve the split-brain
before the IO can resume normally on the file. To get around this,
the patch does the following things:
i) retains the dirty xattrs on the file
ii) avoids marking the last of the good copies as bad (or accused)
in case it is the one to go down during the course of a write.
iii) fails that particular write with the appropriate errno.
This way, we still have one good copy left despite the split-brain situation
which when it is back online, will be chosen as source to do the heal.

AFR sets transaction.pre_op[] array even before actually doing the
pre-op on-disk. Therefore, AFR must not only consider the pre_op[] array
but also the failed_subvols[] information before setting the pre_op_done[]
flag. This patch fixes that.

Problem:
When io-threads is enabled on the client side, io-threads destroys the
call-stub in which the loc is stored as soon as the c-stack unwinds.
Because afr is creating a syncop with the address of loc passed in
setxattr by the time syncop tries to access it, io-threads would have
already freed the call-stub. This will lead to crash.
Fix:
Copy loc to frame->local and use it's address.

Specifically when a directory tree is removed (rm -rf)
while a brick is down, both the directory index and the
name indices of the files and subdirs under it will remain.
Self-heal will need to pick up these and remove them.
Towards this, afr sh will now also crawl indices/entry-changes
and call an rmdir on the dir if the directory index is stale.
On the brick side, rmdir fop has been implemented for index xl,
which would delete the directory index and its contents if present
in a synctask.

Problem: For a read on a file in metadata split-brain:
1.lookup_done resets event_generation to zero.
2. readv is issued, goes to inode refresh due to mismatching event_gen.
3. After refresh is successful, we update event_generation, data and
metdata readable.
3. We then call afr_read_txn_refresh_done() which in turn calls
afr_inode_get_readable() but doesn't check for EIO. So afr_readv_wind
is called with local->readable (which is populated with data_readable),
thus winding the read to a brick.
4. Also, further parallel reads that come directly go to the wind path
because there is no inode_refresh needed.
Fix:
1.For any afr_read_txn(), readable must be an intersection of data and metadata
readable.
2.Check for EIO in afr_read_txn_refresh_done().

Problem:
Since commit 8eaa3506ead4f11b81b146a9e56575c79f3aad7b, in replica 3, if a
brick is down and a create fails on the other 2 brick with EDQUOT, we consider
it an unsymmetric error and hence do not do post-op. So the dirty xattr
remains set on the parent dir, leading to conservative merges during heal when
all bricks are up. i.e. a file deleted on the source might re-appear after heal.
Fix:
Consider ENOSPC and EDQUOT as symmetric errors since there is no
possibility of partial inode or entry modification operations possible when
quota is enabled. IOW, if quota reports EDQUOT, the no. of bytes written
(or not written) will be the same on all bricks of the replica.
Likewise, the entry operation (create, mkdir...) will either succeed or
not succeed on all bricks.

When there is a failure afr was not unwinding xdata to xlators above.
xdata need not be NULL on failures. So it is important to send it
to parent xlators.

DHT expects GF_PREOP_CHECK_FAILED to be present in xdata_rsp in case of mkdir
failures because of stale layout. But AFR was unwinding null xdata_rsp in case
of failures. This was leading to mkdir failures just after remove-brick. Unwind
the xdata_rsp in case of failures to make sure the response from brick reaches
dht.
