* glusterd: add a cli command to trigger a statedump on a clientPoornima G2017-01-235-0/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this, we will be able to trigger statedumps on remote Gluster clients, mainly targetted for applications using libgfapi. Design: SIGUSR signal is the most comman way of taking a statedump in Gluster. But it cannot be used for libgfapi based processes, as the process loading the library might have already consumed SIGUSR signal. Hence going by the command way. One has to issue a Gluster command to initiate a statedump on the libgfapi based client. The command takes hostname and PID as an argument. All the glusterds in the cluster, check if they are connected to the specified hostname, and send an RPC request to all the connected clients from that hostname (via the mgmt connection).

* glusterd, rda: If parallel readdir is enabled, split the cache limitPoornima G2017-01-233-2/+78
| | | | | | | | | | | | | | | | | | | With patch http://review.gluster.org/#/c/16072/ readdir-ahead can be loaded as a child of dht. i.e. there can be more than one instance of readdir-ahead in client process. In this case the rda-cache-size should be split among all the readdir-ahead instances. Also the value of rda-request-size is considered as the minimum cache size of any readdir-ahead instance.

* cluster/ec: Do not start heal on good file while IO is going onAshish Pandey2017-01-202-4/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Write on a file has been slowed down significantly after http://review.gluster.org/#/c/13733/ RC : When update fop starts on a file, it sets dirty flag at the start and remove it at the end which make an index entry in indices/xattrop. During IO, SHD scans this and finds out an index and starts heal even if all the fragments are healthy and up tp date. This heal takes inodelk for different types of heal. If the IO is for long time this will happen in every 60 seconds. Due to this extra, unneccessary locking, IO gets slowed down. Solution: Before starting any type of heal check if file needs heal or not.

However we should bypass this validation with a force option if users really want to have add-brick to go through at the sake of the corner cases of data loss issue. The original problem of add-brick getting failed when layout is not set will still be a problem with a force option as the issue has to be taken care in the DHT layer.

The commands affected: 1) Attach tier will trigger this process instead of old one 2) tier start and tier start force will also trigger this process. 3) volume status [tier] will show tier daemon as a process instead of task and normal tier status and tier detach status works. 4) tier stop implemented. 5) detach tier implemented separately along with new detach tier status 6) volume tier volname status will work using the changes. 7) volume set works This patch has separated the tier translator from the legacy DHT rebalance code. 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: __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.

* feature/dht: undo partially successful dir renameCsaba Henk2017-01-114-7/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As with dht, dirs are present on all subvolumes, renaming them is a compound operation and thus a partial success + partial failure scenario is possible, resulting in an inconsistent state. For purposes of reproduction, such a scenario can easily be produced by stopping the volume, edit the volfile of a certain subvolume to get at an "option read-only on" setting, and then restart the volume. Thus those operations that are to make change on the affected subvolume will fail with EROFS. To handle such scenarios, we introduce an in-memory cache where we record the return values obtained from the subvolumes. At the final stage of the dir rename operation we check if it's a partial success/fail situation. If yes, then we perform a reverse rename op on those subvolumes where the operation succeeded.

* dht: At places needed use STACK_WIND_COOKIEPoornima G2017-01-0910-654/+664
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: frame has a void * cookie pointer. In case of STACK_WIND_COOKIE frame->cookie is assigned to what is sent by the caller. In case of STACK_WIND frame->cookie is assigned to point point to the frame itself. For ease of coding, at many places, the cookie in the cbk is used to get the pointer to the next xl. This is inconsistent when STACK_WIND_TAIL comes into picture. Eg: dht_setxattr () { for (i = 0 ; i < conf->subvolume_cnt ; i++) { STACK_WIND (..dht_checking_pathinfo_cbk, conf->subvolumes[i] ..); } dht_checking_pathinfo_cbk (...void *cookie...) { prev = cookie; ... for (i = 0; i < conf->subvolume_cnt; i++) { if (conf->subvolumes[i] == prev->this) { ... } } } Consider the below graph: dht (parent) readdir-ahead => Doesn't define setxattr and uses STACK_WIND_TAIL protocol-client With this graph, when dht_checking_pathinfo_cbk is called, cookie will have frame pointing to protocol-client. i.e. prev->this will be protocol-client. But dht was expecting it to be readdir-ahead as it has stored in conf->subvolumes[i] Solution: Hence, as a thumb rule, if cbk is using cookie, then we explicitly call STACK_WIND_COOKIE.

Usage: # gluster volume get all cluster.max-op-version Example output: Option Value ------ ----- cluster.max-op-version 30900 NOTE: The only way to test this feature for now is to set the GD_OP_VERSION_MAX macro to different values (30800 for 3.8,30900 for 3.9, and so on) and rebuild glusterd. Since the regression test framework currently doesn't have support to simulate these tests, there are no accompanying regression tests for this feature. It should be possible to add tests once glusto comes in and makes it easier to run a heterogeneous cluster.

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.

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

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.
