* ctime: Enable ctime feature by defaultKotresh HR2018-11-113-8/+0
| | | | | | | | | | | | | | | | | | | | This patch does following. 1. Enable ctime feature by default. 2. Earlier, to enable the ctime feature, two options needed to be enabled a. gluster vol set <volname> utime on b. gluster vol set <volname> ctime on This is inconvenient from the usability point of view. Hence changed it to following single option a. gluster vol set <volname> ctime on fixes: bz#1624724 Change-Id: I04af0e5de1ea6126c58a06ba8a26e22f9f06344e Signed-off-by: Kotresh HR <khiremat@redhat.com>

| | | | | | | | | | | | | | | | | | | We add dummy interrupt handling for the FLUSH fuse message. It can be enabled by the "--fuse-flush-handle-interrupt" hidden command line option, or "-ofuse-flush-handle-interrupt=yes" mount option. It serves no other than diagnostic & demonstational purposes -- to exercise the interrupt handling framework a bit and to give an usage example. Documentation is also provided that showcases interrupt handling via FLUSH. Change-Id: I522f1e798501d06b74ac3592a5f73c1ab0590c60 updates: #465 Signed-off-by: Csaba Henk <csaba@redhat.com>

* afr: thin-arbiter 2 domain locking and in-memory stateRavishankar N2018-10-251-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2 domain locking + xattrop for write-txn failures: -------------------------------------------------- - A post-op wound on TA takes AFR_TA_DOM_NOTIFY range lock and AFR_TA_DOM_MODIFY full lock, does xattrop on TA and releases AFR_TA_DOM_MODIFY lock and stores in-memory which brick is bad. - All further write txn failures are handled based on this in-memory value without querying the TA. - When shd heals the files, it does so by requesting full lock on AFR_TA_DOM_NOTIFY domain. Client uses this as a cue (via upcall), releases AFR_TA_DOM_NOTIFY range lock and invalidates its in-memory notion of which brick is bad. The next write txn failure is wound on TA to again update the in-memory state. - Any incomplete write txns before the AFR_TA_DOM_NOTIFY upcall release request is got is completed before the lock is released. - Any write txns got after the release request are maintained in a ta_waitq. - After the release is complete, the ta_waitq elements are spliced to a separate queue which is then processed one by one. - For fops that come in parallel when the in-memory bad brick is still unknown, only one is wound to TA on wire. The other ones are maintained in a ta_onwireq which is then processed after we get the response from TA.

* glusterd: ensure volinfo->caps is set to correct value.Sanju Rakonde2018-10-251-0/+9
| | | | | | | | | | | | | | | | | With the commit febf5ed4848, during the volume create op, we are setting volinfo->caps to 0, only if any of the bricks belong to the same node and brickinfo->vg[0] is null. Previously, we used to set volinfo->caps to 0, when either brick doesn't belong to the same node or brickinfo->vg[0] is null. With this patch, we set volinfo->caps to 0, when either brick doesn't belong to the same node or brickinfo->vg[0] is null.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch https://review.gluster.org/#/c/glusterfs/+/19135/ has optimised glusterd test cases by clubbing the similar test cases into a single test case. https://review.gluster.org/#/c/glusterfs/+/19135/15/tests/bugs/glusterd/bug-1293414-import-brickinfo-uuid.t test case has been deleted and added as a part of tests/bugs/glusterd/optimized-basic-testcases-in-cluster.t In the original test case, we create a volume with two bricks, each on a separate node(N1 & N2). From another node in cluster(N3), we try to detach a node which is hosting bricks. It fails. In the new test, we created volume with single brick on N1. and from another node in cluster, we tried to detach N1. we expect peer detach to fail, but peer detach was success as the node is hosting all the bricks of volume. Now, changing the new test case to cover the original test case scenario.

* api: fill out attribute information if not validRaghavendra Gowdappa2018-10-172-0/+137
| | | | | | | | | | | | | | | | | translators like readdir-ahead selectively retain entry information of iatt (gfid and type) when rest of the iatt is invalidated (for write invalidating ia_size, (m)(c)times etc). Fuse-bridge uses this information and sends only entry information in readdirplus response. However such option doesn't exist in gfapi.

* features/shard: Hold a ref on base inode when adding a shard to lru listKrutika Dhananjay2018-10-165-7/+106
| | | | | | | | | | | | | | | | | | | | | | | | | In __shard_update_shards_inode_list(), previously shard translator was not holding a ref on the base inode whenever a shard was added to the lru list. But if the base shard is forgotten and destroyed either by fuse due to memory pressure or due to the file being deleted at some point by a different client with this client still containing stale shards in its lru list, the client would crash at the time of locking lru_base_inode->lock owing to illegal memory access. So now the base shard is ref'd into the inode ctx of every shard that is added to lru list until it gets lru'd out. The patch also handles the case where none of the shards associated with a file that is about to be deleted are part of the LRU list and where an unlink at the beginning of the operation destroys the base inode (because there are no refkeepers) and hence all of the shards that are about to be deleted will be resolved without the existence of a base shard in-memory. This, if not handled properly, could lead to a crash. Change-Id: Ic15ca41444dd04684a9458bd4a526b1d3e160499 updates: bz#1605056 Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com>

* afr: prevent winding inodelks twice for arbiter volumesRavishankar N2018-10-101-0/+44
| | | | | | | | | | | | | | | | | | Problem: In an arbiter volume, if there is a pending data heal of a file only on arbiter brick, self-heal takes inodelks twice due to a code-bug but unlocks it only once, leaving behind a stale lock on the brick. This causes the next write to the file to hang. Fix: Fix the code-bug to take lock only once.

* rpc: make binding to port 0 as the default if no option is providedAmar Tumballi2018-10-021-2/+5
| | | | | | | | | | | | | | | | | | | | | | | Right now, if no option is provided, the default port is assumed, which is 24007. Ideally, for 'glusterfsd' processes, it is better to not assume there are any ports given, so it can start listening on any port which is available. This helps us to cleanup the dependencies on glusterd from glusterfsd at the moment. No changes would be done to glusterd code, but making the right defaults helps to make glusterfsd more independent process later.

| | | | | | | | | | | | | | | | | | | | With this change when SHD starts the index crawl it requests all the clients to release the AFR_TA_DOM_NOTIFY lock so that clients will know the in memory state is no more valid and any new operations needs to query the thin-arbiter if required. When SHD completes healing all the files without any failure, it will again take the AFR_TA_DOM_NOTIFY lock and gets the xattrs on TA to see whether there are any new failures happened by that time. If there are new failures marked on TA, SHD will start the crawl immediately to heal those failures as well. If there are no new failures, then SHD will take the AFR_TA_DOM_MODIFY lock and unsets the xattrs on TA, so that both the data bricks will be considered as good there after.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * One #!/usr/bin/env python and three #!/usr/bin/python were overlooked in all the other python fixups. Ugh. * Two new python files missed the memo about #!/usr/bin/python3. * One #!/usr/bin/env bash. Various distribution packaging policies have strong wording about the use of #!/usr/bin/env ... Note: this patch does not change the use of #!/usr/bin/env bash in the two files extras/{clang-checker.sh,check_goto.pl} as these are not included in any packages. (Although I'm not actually sure why anyone would ever use '/usr/bin/env {sh,bash}' as I'm not aware of any version-specific differences like there are with, e.g., python.) * One #!/usr/bin/bash. On Fedora and CentOS > 6, /bin is a symlink to /usr/bin, so it makes little difference. But Debian & Ubuntu still have separate /bin and /usr/bin; and sh and bash are in /bin, not /usr/bin. (Historically, in BSD and SYSV Unix it was /bin/sh.) Note: Fedora and CentOS package build runs a script that converts all /bin/sh and /bin/bash to /usr/bin/sh and /usr/bin/bash.

| | | | | | | | | | | | | | | | | | | | | | | | | | | It wouldn't make sense to allow iostats file to be written in *any* directory. While the formating makes sure we try to append io-stats-name for the file, so overwriting existing file is slim, but in any case it makes sense to restrict dumping to one directory. Below are the sample commands, and files created for the corresponding values: $ setfattr -n trusted.io-stats-dump -v file-for-dump $M0 In this case, the file would be in /var/run/gluster/file-for-dump $ setfattr -n trusted.io-stats-dump -v /dir1/dir2/file-for-dump $M0 In this case, then the dump file is in /var/run/gluster/dir1-dir2-file-for-dump Note that the value passed for this virtual xattr would be treated as a file, and even if the value has '/' in it, it would be changed to '-' for sanity.

* cluster/afr: Delegate name-heal when possiblePranith Kumar K2018-09-041-0/+112
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: When name-self-heal is triggered on the mount, it blocks lookup until name-self-heal completes. But that can lead to hangs when lot of clients are accessing a directory which needs name heal and all of them trigger heals waiting for other clients to complete heal. Fix: When a name-heal is needed but quorum number of names have the file and pending xattrs exist on the parent, then better to delegate the heal to SHD which will be completed as part of entry-heal of the parent directory. We could also do the same for quorum-number of names not present but we don't have any known use-case where this is a frequent occurrence so not changing that part at the moment. When there is a gfid mismatch or missing gfid it is important to complete the heal so that next rename doesn't assume everything is fine and perform a rename etc fixes bz#1622821 Change-Id: I8b002c85dffc6eb6f2833e742684a233daefeb2c Signed-off-by: Pranith Kumar K <pkarampu@redhat.com>

* libgfchangelog: Fix changelog history APIKotresh HR2018-08-313-0/+279
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: If requested start time and end time doesn't fall into first HTIME file, then history API fails even though continuous changelogs are avaiable for the requested range in other HTIME files. This is induced by changelog disable and enable which creates fresh HTIME index file. Cause and Analysis: Each HTIME index file represents the availability of continuous changelogs. If changelog is disabled and enabled, a new HTIME index file is created represents non availability of continuous changelogs. So as long as the requested start and end falls into single HTIME index file and not across, history API should succeed. But History API checks for the changelogs only in first HTIME index file and errors out if not available. Fix: Check in all HTIME index files for availability of continuous changelogs for requested change. fixes: bz#1622549 Change-Id: I80eeceb5afbd1b89f86a9dc4c320e161907d3559 Signed-off-by: Kotresh HR <khiremat@redhat.com>
