* glusterd: double-check whether brick is alive for statsJeff Darcy2017-02-021-3/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | With multiplexing, our tests detach bricks from their host processes without glusterd being involved. Thus, when we ask glusterd to fetch profile info, it will try to fetch from a brick that's actually not present any more. While it can handle the process being dead and its RPC connection being closed, it barfs if it gets a negative response from a live brick process. This is not a problem in normal use, because the brick can't disappear without glusterd seeing it. The fix is to double check that the brick is actually running, by looking for its pidfile which the tests *do* clean up as part of killing a brick.

* libglusterfs+transport+io-threads: fix 256KB stack abuseJeff Darcy2017-02-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Some functions were allocating 64K booleans, which are (crazily) mapped to 4-byte ints, for a total of 256KB per call. Changed to use bitfields instead, so usage is now only 8KB per call. This was the impediment to changing the io-threads stack size, so that has been adjusted too.

* core: run many bricks within one glusterfsd processJeff Darcy2017-02-0131-453/+1200
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

| | | | | | | | | | | | | | | | | | | | | | Problem: In up_(f)removexattr() dict_for_key_value() is used to create a new dict. This dict is not correctly unref'd and gets leaked.

While reviewing the code in up_(f)setxattr() for a similar problem, it was noticed that there is an extra dict created. There is no need for this copy, upcall_local_init() can just take the dict that was passed as argument to the FOP.

* afr: Avoid resetting event_gen when brick is always downRavishankar N2017-01-123-19/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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

But if opendir fails it errors out resulting in the brick process going down. The error due to which opendir failed is not logged.

* glusterd, cli: Get global options through volume get functionalitySamikshan Bairagya2016-12-305-29/+201
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently it is not possible to retrieve values of global options by using the 'gluster volume get' functionality if there are no volumes present. In order to get the global options one has to use 'gluster volume get' with a specific volume name. This usage makes the illusion as though the option is set only on one volume, which is incorrect. When setting the global options, 'gluster volume set' provides a way to set them using the volume name as 'all'. Similarly, retrieving the global options should be made possible by using the volume name 'all' with the 'gluster volume get' functionality. This patch adds that functionality to 'volume get' Usage: # gluster volume get all <OPTION/all> Change-Id: Ic2fdb9eda69d4806d432dae26d117d9660fe6d4e BUG: 1378842 Signed-off-by: Samikshan Bairagya <samikshan@gmail.com> Reviewed-on: http://review.gluster.org/15563 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: Atin Mukherjee <amukherj@redhat.com>

* cluster/afr: Fix missing name indices due to EEXIST errorKrutika Dhananjay2016-12-271-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
