* cluster/afr: Heal entries when there is a source & no healed_sinkskarthik-us2019-10-171-0/+89
| | | | | | | | | | | | | | | | | | | | Problem: In a situation where B1 blames B2, B2 blames B1 and B3 doesn't blame anything for entry heal, heal will not complete even though we have clear source and sinks. This will happen because while doing afr_selfheal_find_direction() only the bricks which are blamed by non-accused bricks are considered as sinks. Later in __afr_selfheal_entry_finalize_source() when it tries to mark all the non-sources as sinks it fails to do so because there won't be any healed_sinks marked, no witness present and there will be a source. Fix: If there is a source and no healed_sinks, then reset all the locked sources to 0 and healed sinks to 1 to do conservative merge.

* afr: support split-brain CLI for replica 3Ravishankar N2019-10-171-0/+111
| | | | | | | | | | | | | | | | | | | | | | | | | Ever since we added quorum checks for lookups in afr via commit bd44d59741bb8c0f5d7a62c5b1094179dd0ce8a4, the split-brain resolution commands would not work for replica 3 because there would be no readables for the lookup fop. The argument was that split-brains do not occur in replica 3 but we do see (data/metadata) split-brain cases once in a while which indicate that there are a few bugs/corner cases yet to be discovered and fixed. Fortunately, commit 8016d51a3bbd410b0b927ed66be50a09574b7982 added GF_CLIENT_PID_GLFS_HEALD as the pid for all fops made by glfsheal. If we leverage this and allow lookups in afr when pid is GF_CLIENT_PID_GLFS_HEALD, split-brain resolution commands will work for replica 3 volumes too. Likewise, the check is added in shard_lookup as well to permit resolving split-brains by specifying "/.shard/shard-file.xx" as the file name (which previously used to fail with EPERM).

* ctime/rebalance: Heal ctime xattr on directory during rebalanceKotresh HR2019-09-271-0/+6
| | | | | | | | | | | | | | | | | | | | | | | After add-brick and rebalance, the ctime xattr is not present on rebalanced directories on new brick. This patch fixes the same. Note that ctime still doesn't support consistent time across distribute sub-volume. This patch also fixes the in-memory inconsistency of time attributes when metadata is self healed.

* dht: Custom xattrs are not healed in case of add-brickroot2019-09-271-0/+67
| | | | | | | | | | | | | | | | | | | | | | Problem: If any custom xattrs are set on the directory before add a brick, xattrs are not healed on the directory after adding a brick.

| | | | | | | | | | | | | | | | | | | | | | | Problem: Since commit 600ba94183333c4af9b4a09616690994fd528478, shd starts healing as soon as it is toggled from disabled to enabled. This was causing the following line in the .t to fail on a 'fast' machine (always on my laptop and sometimes on the jenkins slaves). EXPECT_NOT "^0$" get_pending_heal_count $V0 because by the time shd was disabled, the heal was already completed. Fix: Increase the no. of files to be healed and make it a variable called FILE_COUNT, should we need to bump it up further because the machines become even faster. Also created pending metadata heals to increase the time taken to heal a file. fixes: bz#1749157 Change-Id: I5a26b08e45b8c19bce3c01ce67bdcc28ed48198d Signed-off-by: Ravishankar N <ravishankar@redhat.com> (cherry picked from commit 724c657995a2e148243eeb78c68b620c6d7714a5)
* performance/md-cache: Do not skip caching of null character xattr valuesAnoop C S2019-08-281-0/+22
| | | | | | | | | | | | | | | | | | | | | | Null character string is a valid xattr value in file system. But for those xattrs processed by md-cache, it does not update its entries if value is null('\0'). This results in ENODATA when those xattrs are queried afterwards via getxattr() causing failures in basic operations like create, copy etc in a specially configured Samba setup for Mac OS clients. On the other side snapview-server is internally setting empty string("") as value for xattrs received as part of listxattr() and are not intended to be cached. Therefore we try to maintain that behaviour using an additional dictionary key to prevent updation of entries in getxattr() and fgetxattr() callbacks in md-cache.

* cluster/ec: honor contention notifications for partially acquired locksXavi Hernandez2019-06-031-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | EC was ignoring lock contention notifications received while a lock was being acquired. When a lock is partially acquired (some bricks have granted the lock but some others not yet) we can receive notifications from acquired bricks, which should be honored, since we may not receive more notifications after that. Since EC was ignoring them, once the lock was acquired, it was not released until the eager-lock timeout, causing unnecessary delays on other clients. This fix takes into consideration the notifications received before having completed the full lock acquisition. After that, the lock will be releaed as soon as possible.

* cluster/ec: fix fd reopenPranith Kumar K2019-05-081-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently EC tries to reopen fd's that have been opened while a brick was down. This is done as part of regular write operations, just after having acquired the locks, and it's sent as a sub-fop of the main write fop. There were two problems: 1. The reopen was attempted on all UP bricks, even if a previous lock didn't succeed. This is incorrect because most probably the open will fail. 2. If reopen is sent and fails, the error is propagated to the main operation, causing it to fail when it shouldn't. To fix this, we only attempt reopens on bricks where the current fop owns a lock, and we prevent any error to be propagated to the main fop. To implement this behaviour an argument used to indicate the minimum number of required answers has overloaded to also include some flags. To make the change consistent, it has been necessary to rename the argument, which means that a lot of files have been changed. However there are no functional changes. This change has also uncovered a problem in discard code, which didn't correctely process requests of small sizes because no real discard fop was being processed, only a write of 0's on some region. In this case some fields of the fop remained uninitialized or with incorrect values. To fix this, a new function has been created to simulate success on a fop and it's used in the discard case. Thanks to Pranith for providing a test script that has also detected an issue in this patch. This patch includes a small modification of this script to force data to be written into bricks before stopping them.

| | | | | | | | | | | | | When eager-lock lock acquisition fails because of say network failures, the local is not being removed from owners_list, this leads to accumulation of waiting frames and the application will hang because the waiting frames are under the assumption that another transaction is in the process of acquiring lock because owner-list is not empty.

* protocol/client: Do not fallback to anon-fd if fd is not openPranith Kumar K2019-04-161-0/+36
| | | | | | | | | | | | | | | | | | | If an open comes on a file when a brick is down and after the brick comes up, a fop comes on the fd, client xlator would still wind the fop on anon-fd leading to wrong behavior of the fops in some cases. Example: If lk fop is issued on the fd just after the brick is up in the scenario above, lk fop will be sent on anon-fd instead of failing it on that client xlator. This lock will never be freed upon close of the fd as flush on anon-fd is invalid and is not wound below server xlator. As a fix, failing the fop unless the fd has FALLBACK_TO_ANON_FD flag.

* cluster/ec: Don't enqueue an entry if it is already healingAshish Pandey2019-04-161-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: 1 - heal-wait-qlength is by default 128. If shd is disabled and we need to heal files, client side heal is needed. If we access these files that will trigger the heal. However, it has been observed that a file will be enqueued multiple times in the heal wait queue, which in turn causes queue to be filled and prevent other files to be enqueued. 2 - While a file is going through healing and a write fop from mount comes on that file, it sends write on all the bricks including healing one. At the end it updates version and size on all the bricks. However, it does not unset dirty flag on all the bricks, even if this write fop was successful on all the bricks. After healing completion this dirty flag remain set and never gets cleaned up if SHD is disabled. Solution: 1 - If an entry is already in queue or going through heal process, don't enqueue next client side request to heal the same file. 2 - Unset dirty on all the bricks at the end if fop has succeeded on all the bricks even if some of the bricks are going through heal.

* cluster/afr: Send truncate on arbiter brick from SHDkarthik-us2019-03-121-0/+38
| | | | | | | | | | | | | | | | | | | Problem: In an arbiter volume configuration SHD will not send any writes onto the arbiter brick even if there is data pending marker for the arbiter brick. If we have a arbiter setup on the geo-rep master and there are data pending markers for the files on arbiter brick, SHD will not mark any data changelog during healing. While syncing the data from master to slave, if the arbiter-brick is considered as ACTIVE, then there is a chance that slave will miss out some data. If the arbiter brick is being newly added or replaced there is a chance of slave missing all the data during sync. Fix: If there is data pending marker for the arbiter brick, send truncate on the arbiter brick during heal, so that it will record truncate as the data transaction in changelog.

* readdir-ahead: do not zero-out iatt in fop cbkRavishankar N2019-01-311-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | ...when ctime is zero. ia_type and ia_gfid always need to be non-zero for things to work correctly. Problem: Commit c9bde3021202f1d5c5a2d19ac05a510fc1f788ac zeroed out the iatt buffer in the cbks of modification fops before unwinding if the ctime in the buffer was zero. This was causing the fops to fail: noticeable when AFR's 'consistent-metadata' option was enabled. (AFR zeros out the ctime when the option is set. See commit 4c4624c9bad2edf27128cb122c64f15d7d63bbc8). Fixes: -Do not zero out the ia_type and ia_gfid of the iatt buff under any circumstance. -Also, fixed _rda_inode_ctx_update_iatts() to always update these values from the incoming buf when ctime is zero. Otherwise we end up with zero ia_type and ia_gfid the first time the function is called *and* the incoming buf has ctime set to zero. fixes: bz#1670253 Reported-By:Michael Hanselmann <public@hansmi.ch> Change-Id: Ib72228892d42c3513c19fc6dfb543f2aa3489eca Signed-off-by: Ravishankar N <ravishankar@redhat.com>
* features/shard: Ref shard inode while adding to fsync listKrutika Dhananjay2019-01-241-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: Lot of the earlier changes in the management of shards in lru, fsync lists assumed that if a given shard exists in fsync list, it must be part of lru list as well. This was found to be not true. Consider this - a file is FALLOCATE'd to a size which would make the number of participant shards to be greater than the lru list size. In this case, some of the resolved shards that are to participate in this fop will be evicted from lru list to give way to the rest of the shards. And once FALLOCATE completes, these shards are added to fsync list but without a ref. After the fop completes, these shard inodes are unref'd and destroyed while their inode ctxs are still part of fsync list. Now when an FSYNC is called on the base file and the fsync-list traversed, the client crashes due to illegal memory access. FIX: Hold a ref on the shard inode when adding to fsync list as well. And unref under following conditions: 1. when the shard is evicted from lru list 2. when the base file is fsync'd 3. when the shards are deleted.

* cluster/afr: Allow lookup on root if it is from ADD_REPLICA_MOUNTkarthik-us2018-12-181-0/+95
| | | | | | | | | | | | | | | | | | | | | Problem: When trying to convert a plain distribute volume to replica-3 or arbiter type it is failing with ENOTCONN error as the lookup on the root will fail as there is no quorum. Fix: Allow lookup on root if it is coming from the ADD_REPLICA_MOUNT which is used while adding bricks to a volume. It will try to set the pending xattrs for the newly added bricks to allow the heal to happen in the right direction and avoid data loss scenarios. Note: This fix will solve the problem of type conversion only in the case where the volume was mounted at least once. The conversion of non mounted volumes will still fail since the dht selfheal tries to set the directory layout will fail as they do that with the PID GF_CLIENT_PID_NO_ROOT_SQUASH set in the frame->root.

* iobuf: Get rid of pre allocated iobuf_pool and use per thread mem poolPoornima G2018-12-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current implementation of iobuf_pool has two problems: - prealloc of 12.5MB memory, this limits the scale factor of the gluster processes due to RAM requirements - lock contention, as the current implementation has one global iobuf_pool lock. Credits for debugging and addressing the same goes to Krutika Dhananjay <kdhananj@redhat.com>. Issue: #410 Hence changing the iobuf implementation to use per thread mem pool. This may theoritically appear to cause perf dip as there is no preallocation. But per thread mem pool will not have significant perf impact as the last allocated memory is kept alive for subsequent allocs, for some time. The worst case would be if iobufs requested are of random sizes each time. The best case is, if we get iobuf request of the same size. From the perf tests, this patch did not seem to cause any perf decrease. Note that, with this patch, the rdma performance is going to degrade drastically. In one of the previous patchsets we had fixes to not degrade rdma perf, but rdma is not supported and also not tested [1]. Hence the decision was to not have code in rdma that is not tested and not supported.

To fix this, merge all stbuf values into local->stbuf and use local->prebuf to store the correct directory attributes.
