* glusterd: keep snapshot bricks separate from regular onesJeff Darcy2017-02-102-13/+24
| | | | | | | | | | | | | | | | | | | | | | | The problem here is that a volume's transport options can change, but any snapshots' bricks don't follow along even though they're now incompatible (with respect to multiplexing). This was causing the USS+SSL test to fail. By keeping the snapshot bricks separate (though still potentially multiplexed with other snapshot bricks including those for other volumes) we can ensure that they remain unaffected by changes to their parent volumes. Also fixed various issues with how the test waits (or more precisely didn't) for various events to complete before it continues.

* afr: all children of AFR must be up to resolve s-brainRavishankar N2017-02-091-0/+66
| | | | | | | | | | | | | | | | | | | | | | | | Problem: The various split-brain resolution policies (favorite-child-policy based, CLI based and mount (get/setfattr) based) attempt to resolve split-brain even when not all bricks of replica are up. This can be a problem when say in a replica 3, the only good copy is down and the other 2 bricks are up and blame each other (i.e. split-brain). We end up healing the file in such a case and allow I/O on it. Fix: A decision on whether the file is in split-brain or not must be taken only if we are able to examine the afr xattrs of *all* bricks of a given replica.

| | | | | | | | | | | | | | | | | | | | | When GlusterD is restarted on a multi node cluster, while syncing the global options from other GlusterD, it checks for quorum and based on which it decides whether to stop/start a brick. However we handle the return code of this function in which case if we don't want to start any bricks the ret will be non zero and we will end up failing the import which is incorrect. Fix is just to ignore the ret code of glusterd_restart_bricks () Change-Id: I37766b0bba138d2e61d3c6034bd00e93ba43e553 BUG: 1420637 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-on: https://review.gluster.org/16574 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com>

* libglusterfs: make memory pools more thread-friendlyJeff Darcy2017-02-021-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Early multiplexing tests revealed *massive* contention on certain pools' global locks - especially for dictionaries and secondarily for call stubs. For the thread counts that multiplexing can create, a more lock-free solution is clearly needed. Also, the current mem-pool implementation does a poor job releasing memory back to the system, artificially inflating memory usage to match whatever the worst case was since the process started. This is bad in general, but especially so for multiplexing where there are more pools and a major point of the whole exercise is to reduce memory consumption. The basic ideas for the new design are these There is one pool, globally, for each power-of-two size range. Every attempt to create a new pool within this range will instead add a reference to the existing pool. Instead of adding pools for each translator within each multiplexed brick (potentially infinite and quite possibly thousands), we allocate one set of size-based pools per *thread* (hundreds at worst). Each per-thread pool is divided into hot and cold lists. Every allocation first attempts to use the hot list, then the cold list. When objects are freed, they always go on the hot list. There is one global "pool sweeper" thread, which periodically reclaims everything in each pool's cold list and then "demotes" the current hot list to be the new cold list. For normal allocation activity, only a per-thread lock need be taken, and even that only to guard against very rare contention from the pool sweeper. When threads start and stop, a global lock must be taken to add them to the pool sweeper's list. Lock contention is therefore extremely low, and the hot/cold lists also provide good locality. A more complete explanation (of a similar earlier design) can be found here: http://www.gluster.org/pipermail/gluster-devel/2016-October/051160.html Change-Id: I5bc8a1ba57cfb553998f979a498886e0d006e665 BUG: 1385758 Signed-off-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-on: https://review.gluster.org/15645 Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
* core: run many bricks within one glusterfsd processJeff Darcy2017-01-3050-136/+403
| | | | | | | | | | | | | | | | | | | | | | | This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process.

Solution: RC - In most of the tests, to check heal count, wildcards are being used. In EXPECT_WITHIN, in if condition, when we use it in double quotes (" "), it gives string with wildcards which does not match with the output of get_pending_heal_count. For example, (0 =~ ^0$). So, "while" loop was running for full time and at the end, after coming out of loop, in next if condition it was matching with the expression without quotes. That is why it was passing. Remove double quotes in "if condition" in EXPECT_WITHIN and match as we are matching it in test_expect_footer.

It now sends the RPCs from the CLI to glusterd separate to the DHT rebalance code. The daemon is now a service, similar to the snapshot daemon, and can be viewed using the volume status command. The code for the validation and commit phase are the same as the earlier tier validation code in DHT rebalance. The “brickop” phase has been changed so that the status command can use this framework. The service management framework is now used. DHT rebalance does not use this framework. This service framework takes care of : *) spawning the daemon, killing it and other such processes. *) volume set options , which are written on the volfile. *) restart and reconfigure functions. Restart is to restart the daemon at two points 1)after gluster goes down and comes up. 2) to stop detach tier. *) reconfigure is used to make immediate volfile changes. By doing this, we don’t restart the daemon. it has the code to rewrite the volfile for topological changes too (which comes into place during add and remove brick). With this patch the log, pid, and volfile are separated and put into respective directories.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: 1. Have a replica 2 volume with bricks b1 and b2 2. Before setting the layout, b1 goes down 3. Set the layout write some data, which gets populated on b2 4. b2 goes down then b1 comes up 5. Add another brick b3, and heal will take place from b1 to b3, which basically have no data 6. Write some data. Both b1 and b3 will mark b2 for pending writes 7. b1 goes down, and b2 comes up 8. b2 gets heald from b1. During heal it removes the data which is already in b2, considering that as stale data. This leads to data loss. Solution: 1. In glusterd stage-op, while adding bricks, check whether the replica count is being increased 2. If yes, then check whether any of the bricks are down at that time 3. If yes, then fail the add-brick to avoid such data loss 4. Else continue the normal operation. This check will work enen when we convert plain distribute volume to replicate Test: 1. Create a replica 2 volume 2. Kill one brick from the volume 3. Try adding a brick to the volume 4. It should fail with all bricks are not up error 5. Cretae a distribute volume and kill one of the brick 6. Try to convert it to replicate volume, by adding bricks. 7. This should also fail.

* cluster/afr: Fix missing name indices due to EEXIST errorKrutika Dhananjay2016-12-272-0/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

RCA: ==== In certain cases, ioc_readv() issues STACK_WIND_TAIL() instead of STACK_WIND(). One such case is when inode_ctx for that file is not present (can happen if readdirp was called, and populates md-cache and serves all the lookups from cache). Consider the following graph: ... io-cache (parent) | readdir-ahead | read-ahead ... Below is the code snippet of ioc_readv calling STACK_WIND_TAIL: ioc_readv() { ... if (!inode_ctx) STACK_WIND_TAIL (frame, FIRST_CHILD (frame->this), FIRST_CHILD (frame->this)->fops->readv, fd, size, offset, flags, xdata); /* Ideally, this stack_wind should wind to readdir-ahead:readv() but it winds to read-ahead:readv(). See below for explaination. */ ... } STACK_WIND_TAIL (frame, obj, fn, ...) { frame->this = obj; /* for the above mentioned graph, frame->this will be readdir-ahead * frame->this = FIRST_CHILD (frame->this) i.e. readdir-ahead, which * is as expected */ ... THIS = obj; /* THIS will be read-ahead instead of readdir-ahead!, as obj expands * to "FIRST_CHILD (frame->this)" and frame->this was pointing * to readdir-ahead in the previous statement. */ ... fn (frame, obj, params); /* fn will call read-ahead:readv() instead of readdir-ahead:readv()! * as fn expands to "FIRST_CHILD (frame->this)->fops->readv" and * frame->this was pointing ro readdir-ahead in the first statement */ ... } Thus, the readdir-ahead's readv() implementation will be skipped, and ra_readv() will be called with frame->this = "readdir-ahead" and this = "read-ahead". This can lead to corruption / hang / other problems. But in this perticular case, when 'frame->this' and 'this' passed to ra_readv() doesn't match, it causes ra_readv() to call ra_readv() again!. Thus the logic of read-ahead readv() falls apart and leads to hang. Solution: ========= Modify STACK_WIND_TAIL() as: STACK_WIND_TAIL (frame, obj, fn, ...) { next_xl = obj /* resolve obj as the variables passed in obj macro can be overwritten in the further instrucions */ next_xl_fn = fn /* resolve fn and store in a tmp variable, before modifying any variables */ frame->this = next_xl; ... THIS = next_xl; ... next_xl_fn (frame, next_xl, params); ... } As a part of http://review.gluster.org/15901/ the caller io-cache was fixed.

Because of the absence of name indices, granular entry healing logic will fail to heal these directories, and worse yet unset pending extended attributes with the assumption that are no entries that need heal. To get around this, a new CLI is introduced which will invoke glfsheal program to figure whether at the time an attempt is made to enable granular entry heal, there are pending heals on the volume OR there are one or more bricks that are down. If either of them is true, the command will be failed with the appropriate error. New CLI: gluster volume heal <VOL> granular-entry-heal {enable,disable} Change-Id: I1f4fe8162813b9068e198965d94169fee4adc099 BUG: 1370410 Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com> Reviewed-on: http://review.gluster.org/15747 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>
* afr: allow I/O when favorite-child-policy is enabledRavishankar N2016-11-271-0/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* cluster/afr: Fix bugs in [f]inodelk/[f]entrylkPranith Kumar K2016-11-261-0/+87
| | | | | | | | | | | | | | | | | | | | | | 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.

* features/index: Delete granular entry indices of already healed directories ↵Krutika Dhananjay2016-11-241-0/+76
| | | | | | | | | | | | | | | | | | | | | | during crawl If granular name indices are already in existence for a volume, and before they are healed, granular entry heal be disabled, a crawl on indices/xattrop will clear the changelogs on these directories. When their corresponding entry-changes indices are crawled subsequently, if it is found that the directories don't need heal anymore, the granular indices are not cleaned up. This patch fixes that problem by ensuring that the zero-xattrop also deletes the stale indices at the level of index translator.
