* afr: fix bug-1363721.t failureRavishankar N2018-05-251-2/+8
| | | | | | | | | | | | | | | | | | | | | | | Problem: In the .t, when the only good brick was brought down, writes on the fd were still succeeding on the bad bricks. The inflight split-brain check was marking the write as failure but since the write succeeded on all the bad bricks, afr_txn_nothing_failed() was set to true and we were unwinding writev with success to DHT and then catching the failure in post-op in the background. Fix: Don't wind the FOP phase if the write_subvol (which is populated with readable subvols obtained in pre-op cbk) does not have at least 1 good brick which was up when the transaction started. Note: This fix is not related to brick muliplexing. I ran the .t 10 times with this fix and brick-mux enabled without any failures.

* Revert "gfapi: return pre/post attributes from glfs_pread/pwrite"ShyamsundarR2018-05-081-1/+1
| | | | | | | | | | | | | | | | | | This reverts commit d01f7244e9d9f7e3ef84e0ba7b48ef1b1b09d809. This is being reverted as the API signatures should adapt to a statx like structure, and also all APIs that need to return pre/post attrs are not complete. As a result, instead of fixing up part of the APIs and then refixing the same in a later release, removing these set of fixes from the branch Additionally fixed up posix-entry-ops.c which was using the new syncop signature Updates: bz#1575386 Change-Id: I35222dadc4a2e97010bc1e6b97b6f83583c311f6

* gluster: Sometimes Brick process is crashed at the time of stopping brickMohit Agrawal2018-04-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Problem: Sometimes brick process is getting crashed at the time of stop brick while brick mux is enabled. Solution: Brick process was getting crashed because of rpc connection was not cleaning properly while brick mux is enabled.In this patch after sending GF_EVENT_CLEANUP notification to xlator(server) waits for all rpc client connection destroy for specific xlator.Once rpc connections are destroyed in server_rpc_notify for all associated client for that brick then call xlator_mem_cleanup for for brick xlator as well as all child xlators.To avoid races at the time of cleanup introduce two new flags at each xlator cleanup_starting, call_cleanup.

This patch does two things: 1) minor cleanup of configure(.ac) to explicitly use python2 2) change all the shebang lines to #!/usr/bin/python2 and add them where they were missing based on warnings emitted during rpmbuild. In a follow-up patch python2 will eventually be changed to python3. Before that python2-isms (e.g. print, string.join(), etc.) need to be converted to python3. Some of those can be rewritten in version agnostic python. E.g. print statements become print() with "from __future_ import print_function". The python 2to3 utility will be used for some of those. Also Aravinda has given guidance in the comments to the first patch for changes. updates: #411 Change-Id: I471730962b2526022115a1fc33629fb078b74338 Signed-off-by: Kaleb S.

* glusterd: mark port_registered to true for all running bricks with brick muxAtin Mukherjee2018-04-051-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | glusterd maintains a boolean flag 'port_registered' which is used to determine if a brick has completed its portmap sign in process. This flag is (re)set in pmap_sigin and pmap_signout events. In case of brick multiplexing this flag is the identifier to determine if the very first brick with which the process is spawned up has completed its sign in process. However in case of glusterd restart when a brick is already identified as running, glusterd does a pmap_registry_bind to ensure its portmap table is updated but this flag isn't which is fine in case of non brick multiplex case but causes an issue if the very first brick which came as part of process is replaced and then the subsequent brick attach will fail. One of the way to validate this is to create and start a volume, remove the first brick and then add-brick a new one. Add-brick operation will take a very long time and post that the volume status will show all other brick status apart from the new brick as down. Solution is to set brickinfo->port_registered to true for all the running bricks when brick multiplexing is enabled.

* Revert "glusterd: handling brick termination in brick-mux"Sanju Rakonde2018-03-291-32/+0
| | | | | | | | | | | | | This reverts commit a60fc2ddc03134fb23c5ed5c0bcb195e1649416b. This commit was causing multiple tests to time out when brick multiplexing is enabled. With further debugging, it's found that even though the volume stop transaction is converted into mgmt_v3 to allow the remote nodes to follow the synctask framework to process the command, there are other callers of glusterd_brick_stop () which are not synctask based.

* glusterd: handling brick termination in brick-muxSanju Rakonde2018-03-281-0/+32
| | | | | | | | | | | | | | | Problem: There's a race between the last glusterfs_handle_terminate() response sent to glusterd and the kill that happens immediately if the terminated brick is the last brick. Solution: When it is a last brick for the brick process, instead of glusterfsd killing itself, glusterd will kill the process in case of brick multiplexing. And also changing gf_attach utility accordingly. Change-Id: I386c19ca592536daa71294a13d9fc89a26d7e8c0 fixes: bz#1545048 BUG: 1545048 Signed-off-by: Sanju Rakonde <srakonde@redhat.com>
* cluster/afr: Make AFR eager-locking similar to ECPranith Kumar K2018-03-141-36/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: 1) Afr's eager-lock only works for data transactions. 2) When there are conflicting writes, write with conflicting region initiates unlock of eager-lock leading to extra pre-ops and post-ops on the file. When eager-lock goes off, it leads to extra fsyncs for random-write workload in afr. Solution (that is modeled after EC): In EC, when there is a conflicting write, it waits for the current write to complete before it winds the conflicted write. This leads to better utilization of network and disk, because we will not be doing extra xattrops and FSYNCs and inodelk/unlock. Moved fd based counters to inode based counters. I tried to model the solution based on EC's locking, but it is not similar to AFR because we had to keep backward compatibility. Lifecycle of lock: ================== First transaction is added to inode->owners list and an inodelk will be sent on the wire. All the next transactions will be put in inode->waiters list until the first transaction completes inodelk and [f]xattrop completely. Once [f]xattrop also completes, all the requests in the inode->waiters list are checked if it conflict with any of the existing locks which are in inode->owners list and if not are added to inode->owners list and resumed with doing transaction. When these transactions complete fop phase they will be moved to inode->post_op list and resume the transactions that were paused because of conflicts. Post-op and unlock will not be issued on the wire until that is the last transaction on that inode. Last transaction when it has to perform post-op can choose to sleep for deyed-post-op-secs value. During that time if any other transaction comes, it will wake up the sleeping transaction and takes over the ownership of the lock and the cycle continues. If the dealyed-post-op-secs expire, then the timer thread will wakeup the sleeping transaction and it will set lock->release to true and starts doing post-op and then unlock. During this time if any other transactions come, they will be put in inode->frozen list. Once the previous unlock comes it will move the frozen list to waiters list and moves the first element from this waiters-list to owners-list and attempts the lock and the cycle continues. This is the general idea. There is logic at the time of dealying and at the time of new transaction or in flush fop to wakeup existing sleeping transactions or choosing whether to delay a transaction etc, which is subjected to change based on future enhancements etc. Fixes: #418 BUG: 1549606 Change-Id: I88b570bbcf332a27c82d2767dfa82472f60055dc Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>
* cluster/ec: avoid delays in self-healXavi Hernandez2018-03-141-0/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Self-heal creates a thread per brick to sweep the index looking for files that need to be healed. These threads are started before the volume comes online, so nothing is done but waiting for the next sweep. This happens once per minute. When a replace brick command is executed, the new graph is loaded and all index sweeper threads started. When all bricks have reported, a getxattr request is sent to the root directory of the volume. This causes a heal on it (because the new brick doesn't have good data), and marks its contents as pending to be healed. This is done by the index sweeper thread on the next round, one minute later. This patch solves this problem by waking all index sweeper threads after a successful check on the root directory. Additionally, the index sweep thread scans the index directory sequentially, but it might happen that after healing a directory entry more index entries are created but skipped by the current directory scan. This causes the remaining entries to be processed on the next round, one minute later. The same can happen in the next round, so the heal is running in bursts and taking a lot to finish, specially on volumes with many directory levels. This patch solves this problem by immediately restarting the index sweep if a directory has been healed.

* tests/bug-1110262.t: fix a race conditionRaghavendra G2018-03-131-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | This test does: 1. mount a volume 2. kill a brick in the volume 3. mkdir (/somedir) In my local tests and in [1], I see that mkdir in step 3 fails because there is no dht-layout on root directory. The reason I think is by the time first lookup on "/" hit dht, a brick was killed as per step 2. This means layout was not healed for "/" and since this is a new volume, no layout is present on it. Note that the first lookup done on "/" by fuse-bridge is not synchronized with parent process of daemonized glusterfs mount completing. IOW, by the time glusterfs cmd executed there is no guarantee that lookup on "/" is complete. So, if step 2 races ahead of fuse_first_lookup on "/", we end up with an invalid dht-layout on "/" resulting in failures. Doint an operation like ls makes sure that lookup on "/" is completed before we kill a brick Change-Id: Ie0c4e442c4c629fad6f7ae850437e3d63fe4bea9 Signed-off-by: Raghavendra G <rgowdapp@redhat.com> BUG: 1543279

* afr: don't treat all cases all bricks being blamed as split-brainRavishankar N2018-02-012-0/+101
| | | | | | | | | | | | | | | | | | | | | | | Problem: We currently don't have a roll-back/undoing of post-ops if quorum is not met. Though the FOP is still unwound with failure, the xattrs remain on the disk. Due to these partial post-ops and partial heals (healing only when 2 bricks are up), we can end up in split-brain purely from the afr xattrs point of view i.e each brick is blamed by atleast one of the others. These scenarios are hit when there is frequent connect/disconnect of the client/shd to the bricks while I/O or heal are in progress. Fix: Instead of undoing the post-op, pick a source based on the xattr values. If 2 bricks blame one, the blamed one must be treated as sink. If there is no majority, all are sources. Once we pick a source, self-heal will then do the heal instead of erroring out due to split-brain.

* cluster/dht: Use percentages for space checkN Balachandran2018-01-021-0/+5
| | | | | | | | | | | | | | | | | With heterogenous bricks now being supported in DHT we could run into issues where files are not migrated even though there is sufficient space in newly added bricks which just happen to be considerably smaller than older bricks. Using percentages instead of absolute available space for space checks can mitigate that to some extent. Marking bug-1247563.t as that used to depend on the easier code to prevent a file from migrating. This will be removed once we find a way to force a file migration failure.

* rpc: merge ssl infra with epoll infraMilind Changire2017-12-121-0/+1
| | | | | | | | | | | | | | | | | | | Patch attempts to use the epoll infra for handling SSL connections as well instead of the socket_poller() thread func. This essentially makes priv->own_thread flag redundant. SSL_connect()/SSL_accept() is now non-blocking which has done away with the localised poll() in ssl_do(). So, ssl_do() has been updated appropriately. own_thread and coincidently socket_poller() thread for SSL processing is now deprecated. Added a timeout to test whether seal-heal daemon is up and running as per Ravi's suggestion. Change-Id: If2b5d7b4fd19e321cb289e08d49a718d2161aafe Signed-off-by: Milind Changire <mchangir@redhat.com>

| | | | | | | | | | | | | | | | Problem: Sometime test case ./tests/bugs/bug-1371806_1.t is failing on centos due to race condition between fresh lookup and setxattr fop. Solution: In selfheal code path we do save mds on inode_ctx, it was not serialize with lookup unwind. Due to this behavior after lookup unwind if mds is not saved on inode_ctx and if any subsequent setxattr fop call it has failed with ENOENT because no mds has found on inode ctx.To resolve it save mds on inode ctx has been serialize with lookup unwind.

* afr: add checks for allowing lookupsRavishankar N2017-11-181-0/+2
| | | | | | | | | | | | | | | | | | | | | | Problem: In an arbiter volume, lookup was being served from one of the sink bricks (source brick was down). shard uses the iatt values from lookup cbk to calculate the size and block count, which in this case were incorrect values. shard_local_t->last_block was thus initialised to -1, resulting in an infinite while loop in shard_common_resolve_shards(). Fix: Use client quorum logic to allow or fail the lookups from afr if there are no readable subvolumes. So in replica-3 or arbiter vols, if there is no good copy or if quorum is not met, fail lookup with ENOTCONN. With this fix, we are also removing support for quorum-reads xlator option. So if quorum is not met, neither read nor write txns are allowed and we fail the fop with ENOTCONN.
