* glusterd: Add multiple checks before attach/start a brickMohit Agrawal2018-07-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In brick mux scenario sometime glusterd is not able to start/attach a brick and gluster v status shows brick is already running Solution: 1) To make sure brick is running check brick_path in /proc/<pid>/fd , if a brick is consumed by the brick process it means brick stack is come up otherwise not 2) Before start/attach a brick check if a brick is mounted or not 3) At the time of printing volume status check brick is consumed by any brick process Test: To test the same followed procedure 1) Setup brick mux environment on a vm 2) Put a breaking point in gdb in function posix_health_check_thread_proc at the time of notify GF_EVENT_CHILD_DOWN event 3) unmount anyone brick path forcefully 4) check gluster v status it will show N/A for the brick 5) Try to start volume with force option, glusterd throw message "No device available for mount brick" 6) Mount the brick_root path 7) Try to start volume with force option 8) down brick is started successfully Change-Id: I91898dad21d082ebddd12aa0d1f7f0ed012bdf69 fixes: bz#1595320 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com>
* glusterd: address test failures with brick mux enabledAtin Mukherjee2018-05-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | This patch addresses following: 1. On volume stop, for the last brick, pmap_registry_remove () is invoked by glusterd. 2. If a brick process is sigkilled, remove all the associated brick instances from the portmap. 3. Bump up PROCESS_UP_TIMEOUT to 45. 4. gf_attach to kill a brick takes more time in mux (which is an issue that needs a fix), but in the interim, give br-state-check.t more time to complete (there are 2 kill_bricks, each taking 120 seconds, and the test usually passes in 30 odd seconds, hence bumping this up to 350 seconds) 5. The test bug-1559004-EMLINK-handling.t is taking ~950 seconds at times on master without mux, in mux cases, when it fails, it is almost at the last iteration, hence bumping the timeout for this test case to reduce regression error rates Updates: bz#1577672 Change-Id: I1922675e112baca4c125c4c094eaa42a11e34e67 Signed-off-by: Atin Mukherjee <amukherj@redhat.com>

* cluster/ec: Don't trigger data/metadata heal on LookupsPranith Kumar K2017-02-261-33/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem-1 If Lookup which doesn't take any locks observes version mismatch it can't be trusted. If we launch a heal based on this information it will lead to self-heals which will affect I/O performance in the cases where Lookup is wrong. Considering self-heal-daemon and operations on the inode from client which take locks can still trigger heal we can choose to not attempt a heal on Lookup. Problem-2: Fixed spurious failure of tests/bitrot/bug-1373520.t For the issues above, what was happening was that ec_heal_inspect() is preventing 'name' heal to happen Problem-3: tests/basic/ec/ec-background-heals.t To be honest I don't know what the problem was, while fixing the 2 problems above, I made some changes to ec_heal_inspect() and ec_need_heal() after which when I tried to recreate the spurious failure it just didn't happen even after a long time.

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-11/+31
| | | | | | | | | | | | | | | | | | | | | | | 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.

* feature/bitrot: Fix recovery of corrupted hardlinkKotresh HR2016-09-082-5/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When a file with hardlink is corrupted in ec volume, the recovery steps mentioned was not working. Only name and metadata was healing but not the data. Cause: The bad file marker in the inode context is not removed. Hence when self heal tries to open the file for data healing, it fails with EIO. Background: The bitrot deletes inode context during forget. Briefly, the recovery steps involves following steps. 1. Delete the entry marked with bad file xattr from backend. Delete all the hardlinks including .glusters hardlink as well. 2. Access the each hardlink of the file including original from the mount. The step 2 will send lookup to the brick where the files are deleted from backend and returns with ENOENT. On ENOENT, server xlator forgets the inode if there are no dentries associated with it. But in case hardlinks, the forget won't be called as dentries (other hardlink files) are associated with the inode. Hence bitrot stube won't delete it's context failing the data self heal. Fix: Bitrot-stub should delete the inode context on getting ENOENT during lookup.

* features/bitrot: do not remove the quarantine handle in forgetRaghavendra Bhat2016-02-291-6/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If an object is marked as bad, then an entry is corresponding to the bad object is created in the .glusterfs/quarantine directory to help scrub status. The entry name is the gfid of the corrupted object. The quarantine handle is removed in below 2 cases. 1) When protocol/server revceives the -ve lookup on an entry whose inode is there in the inode table (it can happen when the corrupted object is deleted directly from the backend for recovery purpose) it sends a forget on the inode and bit-rot-stub removes the quarantine handle in upon getting the forget. refer to the below commit f853ed9c61bf65cb39f859470a8ffe8973818868: http://review.gluster.org/12743) 2) When bit-rot-stub itself realizes that lookup on a corrupted object has failed with ENOENT. But with step1, there is a problem when the bit-rot-stub receives forget due to lru limit exceeding in the inode table. In such cases, though the corrupted object is not deleted (either from the mount point or from the backend), the handle in the quarantine directory is removed and that object is not shown in the bad objects list in the scrub status command. So it is better to follow only 2nd step (i.e. bit-rot-stub removing the handle from the quarantine directory in -ve lookups). Also the handle has to be removed when a corrupted object is unlinked from the mount point itself.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of open * This patch brings in the changes where object versioning is done in write and truncate fops instead of tracking them in open and create fops. This model works for both regular and anonymous fds. It also removes the race associated with open calls, create and lookups. This patch follows the below method for object versioning and notifications: Before sending writev on the fd, increase the ongoing version first. This makes anonymous fd write similar to the regular fd write by having the ongoing version increased before doing the write. Do following steps to do versioning: 1) For anonymous fds set the fd context (so that release is invoked) and add the fd context to the list maintained in the inode context. For regular fds the above think would have been done in open itself. 2) Increase the on-disk ongoing version 3) Increase the in memory ongoing version and mark inode as non-dirty 3) Once versioning is successfully done send write operation. If versioning fails, then fail the write fop. 5) In writev_cbk mark inode as modified.

* tests/bitrot-stub: Object versioning test(s)Venky Shankar2015-04-082-0/+191
This patch introduces basic object versioning test(s) which is required for bitrot detection to work correctly. Basic test(s) such as opening a file in read-only mode, single open, multiple open()s are covered on FUSE mount _only_ as stub does not support anonymous fds yet. For this reason, the test case disables open-behind. Actual verification is implemented as a C source which makes use of the same on-disk data structures as used by the stub code. The data structures are moved to separate header file which is included by the test script. Such modularization helps in future enhancements to keep the version "data type" opaque and provide handful of APIs version checking (equal/greater/etc..). [ This is just a start and should grow over time as stub is enhanced and codebase matures. ] Change-Id: Ibee20e65a15b56bbdd59fd2703f9305b115aec7a BUG: 1201724 Signed-off-by: Venky Shankar <vshankar@redhat.com> Reviewed-on: http://review.gluster.org/10140 Reviewed-by: Raghavendra Bhat <raghavendra@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
