* dht/rebalance: Crawler performance improvementSusant Palai2017-04-101-127/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The job of the crawler in rebalance is to fetch files from each local subvolume and push them to migration queue if it is eligible for migration. And we do a lookup on the entries received to figure out the eligibilty. Since, the lookup done is on a local subvolume we receive linkto files and regular files as well. This requires us to do two lookups. first: do a lookup on the file to figure out whether it is a linkto file second: do a lookup on the file to figure out if it should be migrated Note: The migrator thread also does one lookup for the file before migration. Optimization: Remove the lookup done by the crawler. Offload these task to the migrator threads. For linkto file verification get the stat and xattr information from readdirp. So in total we have one lookup instead of three for each entry. Performance numbers: Create two node, two brick setup. Created 100000 files. And started rebalance. Since, there is no add-brick, no files will be migrated and we will get the crawler performance.

* cluster/dht: Modify local->loc.gfid in thread safe mannerPranith Kumar K2017-04-041-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: local->loc.gfid in dht_lookup_directory() will be null-gfid for a fresh lookup. dht_lookup_dir_cbk() updates local->loc.gfid while in other thread dht_lookup_directory() is still winding lookup calls to subvolumes so there is a chance of partial gfid being seen by EC. We saw in 12x(4+2) volume, ec is receiving an loc where the gfid has last 10 bytes matching with the gfid of the directory and the first 4 bytes are all-zeros.

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.

* 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.

Consider following case, a user is trying to rename a file which he is not permitted. So the rename fails with EACESS and when rename tries to cleanup the linkto file, it fails. The above issue happens when rename/00.t test executed on nfs-ganesha clients : Steps executed in script * create a file "abc" using root * rename the file "abc" to "xyz" using a non root user, it fails with EACESS * delete "abc" * create directory "abc" using root * again try ot rename "abc" to "xyz" using non root user, test hungs here which slowly leds to OOM kill of ganesha process RCA put forwarded by Du for OOM kill of ganesha Note that when we hit this bug, we've a scenario of a dentry being present as: * a linkto file on one subvol * a directory on rest of subvols When a lookup happens on the dentry in such a scenario, the control flow goes into an infinite loop of: dht_lookup_everywhere dht_lookup_everywhere_cbk dht_lookup_unlink_cbk dht_lookup_everywhere_done dht_lookup_directory (as local->dir_count > 0) dht_lookup_dir_cbk (sets to local->need_selfheal = 1 as the entry is a linkto file on one of the subvol) dht_lookup_everywhere (as need_selfheal = 1). This infinite loop can cause increased consumption of memory due to: 1) dht_lookup_directory assigns a new layout to local->layout unconditionally 2) Most of the functions in this loop do a stack_wind of various fops. This results in growing of call stack (note that call-stack is destroyed only after lookup response is received by fuse - which never happens in this case) Thanks Du for root causing the oom kill and Sushant for suggesting the fix Change-Id: I1e16bc14aa685542afbd21188426ecb61fd2689d BUG: 1397052 Signed-off-by: Jiffin Tony Thottan <jthottan@redhat.com> Reviewed-on: http://review.gluster.org/15894 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

GF_EVENT_CHILD_MODIFIED : Issued by afr/dht/ec GF_EVENT_CHILD_DOWN : Issued when any of the protocol client disconnects. These events get modified at the dht/afr/ec layers. Here is a brief on the same. DHT: - All the subvolumes reported once, and atleast one child came up, then GF_EVENT_CHILD_UP is issued - connect GF_EVENT_CHILD_UP is issued - disconnect GF_EVENT_CHILD_MODIFIED is issued - All the subvolumes disconnected, GF_EVENT_CHILD_DOWN is issued AFR: - First subvolume came up, then GF_EVENT_CHILD_UP is issued - Subsequent subvolumes coming up, results in GF_EVENT_CHILD_MODIFIED - Any of the subvolumes go down, then GF_EVENT_SOME_CHILD_DOWN is issued - Last up subvolume goes down, then GF_EVENT_CHILD_DOWN is issued Until the patch [1] introduced GF_EVENT_SOME_CHILD_UP, GF_EVENT_CHILD_MODIFIED was issued by afr/dht when any of the subvolumes go up or down. Now with md-cache changes, there is a necessity to differentiate between child up and down. Hence, introducing GF_EVENT_SOME_DESCENDENT_DOWN/UP and getting rid of GF_EVENT_CHILD_MODIFIED.

We barely support netbsd7 as it is. Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with libglusterfs? A cut-and-paste mistake? It has no references to symbols in libglusterfs. Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_ regex that matches the same lines as the _extended_ regex "/#(ifndef|define|endif)/". To match the extended regex sed needs to be run with -r on Linux; with -E on *BSD. However NetBSD's and FreeBSD's sed helpfully also provide -r for compatibility. Using a basic regex avoids having to use a kludge in order to run sed with the correct option on OS X. Note 4. Not copying the bit of xdrgen that inserts copyright/license boilerplate. AFAIK it's silly to pretend that machine generated files like these can be copyrighted or need license boilerplate. The XDR source files have their own copyright and license; and their copyrights are bound to be more up to date than old boilerplate inserted by a script. From what I've seen of other Open Source projects -- e.g. gcc and its C parser files generated by yacc and lex -- IIRC they don't bother to add copyright/license boilerplate to their generated files. It appears that it's a long-standing feature of make (SysV, BSD, gnu) for out-of-tree builds to helpfully pretend that the source files it can find in the VPATH "exist" as if they are in the $cwd. rpcgen doesn't work well in this situation and generates files with "bad" #include directives. E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`, you get an #include directive in the generated .c file like this: ... #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h" ... which (obviously) results in compile errors on out-of-tree build because the (generated) header file doesn't exist at that location. Compared to `rpcgen ./glusterfs3-xdr.x` where you get: ... #include "glusterfs3-xdr.h" ... Which is what we need. We have to resort to some Stupid Make Tricks like the addition of various .PHONY targets to work around the VPATH "help". Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/... looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though. And don't delete the -I$(top_builddir)/rpc/xdr/... bits Change-Id: Iba6ab96b2d0a17c5a7e9f92233993b318858b62e BUG: 1330604 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/14085 Tested-by: Niels de Vos <ndevos@redhat.com> 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: Niels de Vos <ndevos@redhat.com>

* dht: "replica.split-brain-status" attribute value is not correctMohit Agrawal2016-09-122-12/+210
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In a distributed-replicate volume attribute "replica.split-brain-status" value does not display split-brain condition though directory is in split-brain. If directory is in split brain on mutiple replica-pairs it does not show full list of replica pairs. Solution: Update the dht_aggregate code to aggregate the xattr value in this specific condition. Fix: 1) function getChoices returns the choices from split-brain status string. 2) function add_opt adding the choices to local buffer to store in dictionary 3) For the key "replica.split-brain-status" function dht_aggregate call dht_aggregate_split_brain_xattr to prepare the list. Test: To verify the patch followed below steps 1) Create a distributed replica volume and create mount point 2) Stop heal daemon 3) Touch file and directories on mount point mkdir test{1..5};touch tmp{1..5} 4) Down brick process on one of the replica set pkill -9 glusterfsd 5) Change permission of dir on mount point chmod 755 test{1..5} 6) Restart brick process on node with force option 7) kill brick process on other node in same replica set 8) Change permission of dir again on mount point chmod 766 test{1..5} 9) Reexecute same step from 4-9 on other replica set also 10) After check heal status on server it will show dir's are in split brain on all replica sets 11) After check the replica.split-brain-status attr on mount point it will show wrong status of split brain. 12) After apply the patch the attribute shows correct value.

* cluster/dht: heal root permission post add-brickSusant Palai2016-09-112-5/+43
| | | | | | | | | | | | | | | | | | | | | | | | | Post add-brick event the new brick will have permission of 755 by default. If the root directory permission was other than 755, that does not get healed to the new brick leading to permission errors/inconsistencies. For choosing source of attr heal we can trust the subvols which have layouts with latest ctime(as part of missing directory heal, we heal the proper attr). In case none of the subvols have layout, return ESTALE to retrigger a fresh lookup. Note: This patch heals the permission of the root directories only. Since, permission healing of directory is not straight forward and required intrusive fix, those are not addressed here.

* dht: udpate stbuf from servers those have layoutSusant Palai2016-09-091-3/+29
| | | | | | | | | | | | | | | | | | | | | | | | Problem: For healing of uid/gid we check if local->stbuf.ia_ctime is lesser than stbuf->ia_ctime (received from brick). If yes then uid/gid is updated to local->prebuf(source of healing). But we merge local->stbuf also form the newly added brick. So if we receive response from the newly added brick first and update the local->stbuf, then local->prebuf will remain empty since the newly added brick will have the latest ctime among all servers. And this can result in healing wrong uid/gids to the rest of servers. Hence, we should update local->stbuf from servers with a layout which will ignore merging stbufs from newly added bricks.
