* dht/hardlink : Remove stale linkto file incase of failureJiffin Tony Thottan2017-06-224-1/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a similar issue fixed for rename in https://review.gluster.org/#/c/16016/ For hardlinks, if cached and hashed subvolumes are different, then it will first create linkto file in hashed using root permission, but actually hardlink creation fails with EACESS and stale linkto file is never removed.All the followup hardlink calls with file name will result ESTALE because linktofile creation fails with EEXIST and follow up lookup on linkto file returns gfid-mismatching(old linkto file) and finally fails with ESTALE Steps to produce : (From link/00.t test from posix-testsuite) Steps executed in script * create a file "abc" using root * change the ownership of file to a non root user * create hardlink "link" for "abc" using a non root user, it fails with EACESS * delete "abc" * create directory "abc" using root * again try to create hadrlink "link" for "abc" using non root user, fails with ESTALE Also tried to fix other bugs in dht_linkfile_create_cbk() and posix_lookup. Thanks Susant for the help in debugging the issue and suggestion for this patch.

* cluster/ec: lk shouldn't be a transactionPranith Kumar K2017-06-161-19/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When application sends a blocking lock, the lk fop actually waits under inodelk. This can lead to a dead-lock. 1) Let's say app-1 takes exculsive-fcntl-lock on the file 2) app-2 attempts an exclusive-fcntl-lock on the file which goes to blocking stage note: app-2 is blocked inside transaction which holds an inode-lock 3) app-1 tries to perform write which needs inode-lock so it gets blocked on app-2 to unlock inodelk and app-2 is blocked on app-1 to unlock fcntl-lock Fix: Correct way to fix this issue and make fcntl locks perform well would be to introduce 2-phase locking for fcntl lock: 1) Implement a try-lock phase where locks xlator will not merge lk call with existing calls until a commit-lock phase. 2) If in try-lock phase we get quorum number of success without any EAGAIN error, then send a commit-lock which will merge locks. 3) In case there are any errors, unlock should just delete the lock-object which was tried earlier and shouldn't touch the committed locks. Unfortunately this is a sizeable feature and need to be thought through for any corner cases. Until then remove transaction from lk call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue1: Consider the followinf sequence of operations: ... nlc_ctx = nlc_ctx_get (inode i1) ....... -> nlc_clear_cache (i1) gets called as a part of nlc_invalidate or any other callers ... GF_FREE (ii nlc_ctx) LOCK (nlc_ctx->lock); -> This will result in crash as the ctx got freed in nlc_clear_cache. Issue2: lookup on dir1/file1 result in ENOENT add cache to dir1 at time T1 .... CHILD_DOWN at T2 lookup on dir1/file2 result in ENOENT add cache to dir1, but the cache time is still T1 lookup on dir1/file2 - should have been served from cache but the cache time is T1 < T2, hence cache is considered as invalid. So, after CHILD_DOWN the right thing would be to clear the cache and restart caching on that inode. Solution: Do not free nlc_ctx in nlc_clear_cache, but only in inode_forget() The fix for both issue1 and 2 is interleaved hence sending it as single patch.

* protocol/server: make listen backlog value as configurableMohammed Rafi KC2017-06-085-7/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | problem: When we call listen from protocol/server, we are giving a hard coded valie of 10 if it is not manually given. With multiplexing, especially when glusterd restarts all clients may try to connect to the server at a time. Which will result in overflowing the queue, and kernel will complain about the errors. Solution: This patch will introduce a volume set command to make backlog value as a configurable. This patch also changes the default values for backlog from 10 to 128. This changes is only applicable for sockets listening from protocol. Example: gluster volume set <volname> transport.listen-backlog 1024 Note: 1 Brick has to be restarted to get this value in effect 2 This changes won't be reflected in glusterd, or other xlators which calls listen. If you need, you have to add this option to the volfile.

* cluster/ec: Update xattr and heal size properlyAshish Pandey2017-06-062-9/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem-1 : Recursive healing of same file is happening when IO is going on even after data heal completes. Solution: RCA: At the end of the write, when ec_update_size_version gets called, we send it only on good bricks and not on healing brick. Due to this, xattr on healing brick will always remain out of sync and when the background heal check source and sink, it finds this brick to be healed and start healing from scratch. That involve ftruncate and writing all of the data again. To solve this, send xattrop on all the good bricks as well as healing bricks. Problem-2: The above fix exposes the data corruption during heal. If the write on a file is going on and heal finishes, we find that the file gets corrupted. RCA: The real problem happens in ec_rebuild_data(). Here we receive the 'size' argument which contains the real file size at the time of starting self-heal and it's assigned to heal->total_size. After that, a sequence of calls to ec_sync_heal_block() are done. Each call ends up calling ec_manager_heal_block(), which does the actual work of healing a block. First a lock on the inode is taken in state EC_STATE_INIT using ec_heal_inodelk(). When the lock is acquired, ec_heal_lock_cbk() is called. This function calls ec_set_inode_size() to store the real size of the inode (it uses heal->total_size). The next step is to read the block to be healed. This is done using a regular ec_readv(). One of the things this call does is to trim the returned size if the file is smaller than the requested size. In our case, when we read the last block of a file whose size was = 512 mod 1024 at the time of starting self-heal, ec_readv() will return only the first 512 bytes, not the whole 1024 bytes. This isn't a problem since the following ec_writev() sent from the heal code only attempts to write the amount of data read, so it shouldn't modify the remaining 512 bytes. However ec_writev() also checks the file size. If we are writing the last block of the file (determined by the size stored on the inode that we have set to heal->total_size), any data beyond the (imposed) end of file will be cleared with 0's. This causes the 512 bytes after the heal->total_size to be cleared. Since the file was written after heal started, the these bytes contained data, so the block written to the damaged brick will be incorrect. Solution: Align heal->total_size to a multiple of the stripe size. Thanks "Xavier Hernandez" <xhernandez@datalab.es> to find out the root cause and to fix the issue.

* glusterd: fix brick start raceAtin Mukherjee2017-06-065-21/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit tries to handle a race where we might end up trying to spawn the brick process twice with two different set of ports resulting into glusterd portmapper having the same brick entry in two different ports which will result into clients to fail connect to bricks because of incorrect ports been communicated back by glusterd. In glusterd_brick_start () checking brickinfo->status flag to identify whether a brick has been started by glusterd or not is not sufficient as there might be cases where while glusterd restarts glusterd_restart_bricks () will be called through glusterd_spawn_daemons () in synctask and immediately glusterd_do_volume_quorum_action () with server-side-quorum set to on will again try to start the brick and in case if the RPC_CLNT_CONNECT event for the same brick hasn't been processed by glusterd by that time, brickinfo->status will still be marked as GF_BRICK_STOPPED resulting into a reattempt to start the brick with a different port and that would result portmap go for a toss and resulting clients to fetch incorrect port. Fix would be to introduce another enum value called GF_BRICK_STARTING in brickinfo->status which will be set when a brick start is attempted by glusterd and will be set to started through RPC_CLNT_CONNECT event. For brick multiplexing, on attach brick request given the brickinfo->status flag is marked to started directly this value will not have any effect. Also this patch removes started_here flag as it looks to be redundant as brickinfo->status.

This is because detaching individual bricks manually from the backend like it is done in the regression test framework by 'kill_brick', fails to send a RPC_CLNT_DISCONNECT to glusterd when multiplexing is enabled. This causes the add-brick command to not fail when one of the bricks are killed using kill_brick in the regression test framework. To fix this, set the brick status to GF_BRICK_STOPPED on the glusterd end during portmap signout. This commit also sets the brick status in glusterd_brick_stop() function so that the brick status is correctly set to 'stopped' even when the function is called independently for individual bricks.

| | | | | | | | | | | | | | | | | | | | | | | | | Problem: When parellel `rm -rf`s were being done from cifs clients, opendir might fail on some replicas with ENOENT. DHT ignores partial opendir failures in dht_fd_cbk() and winds readdirs on those replicas. Afr inode refresh (as a part of readdirp read_txn) sees in its fd context that the state of the fds is *not* AFR_FD_OPENED and bails out to afr_inode_refresh_done() without doing a refresh. When this happens, the errno is set as EIO due to lack of readable subvols, logging split-brain messages in the logs. Fix: Introduce an errno argument to afr_inode_refresh_do() to bail out with the right error value when inode refresh is not performed.

Dependency on defrag led to crash when migration was triggered from client. Note: This functionality is not available for tiered volumes. Migration from tier served client will fail with ENOTSUP. usage (But refer to the steps mentioned below to avoid any issues) : setfattr -n "trusted.distribute.migrate-data" -v "1" <filename> The purpose of fixing the on-demand client migration was to give a workaround where the user has lots of empty directories compared to files and want to do a remove-brick process. Here are the steps to trigger file migration for remove-brick process from client. (This is highly recommended to follow below steps as is) Let's say it is a replica volume and user want to remove a replica pair named brick1 and brick2. (Make sure healing is completed before you run these steps) Step-1: Start remove-brick process - gluster v remove-brick <volname> brick1 brick2 start Step-2: Kill the rebalance daemon - ps aux | grep glusterfs | grep rebalance\/ | awk '{print $2}' | xargs kill Step-3: Do a fresh mount as mentioned here - glusterfs -s ${localhostname} --volfile-id rebalance/$volume-name /tmp/mount/point Step-4: Go to one of the bricks (among brick1 and brick2) - cd <brick1 path> Step-5: Run the following command. - find . -not \( -path ./.glusterfs -prune \) -type f -not -perm 01000 -exec bash -c 'setfattr -n "distribute.fix.layout" -v "1" ${mountpoint}/$(dirname '{}')' \; -exec setfattr -n "trusted.distribute.migrate-data" -v "1" ${mountpoint}/'{}' \; This command will ignore the linkto files and empty directories. Do a fix-layout of the parent directory. And trigger a migration operation on the files. Step-6: Once this process is completed do "remove-brick force" - gluster v remove-brick <volname> brick1 brick2 force Note: Use the above script only when there are large number of empty directories. Since the script does a crawl on the brick side directly and avoids directories those are empty, the time spent on fixing layout on those directories are eliminated(even if the script does not do fix-layout on empty directories, post remove-brick a fresh layout will be built for the directory, hence not affecting application continuity). Detailing the expectation for hardlink migartion with this patch: Hardlink is migrated only for remove-brick process. It is highly essential to have a new mount(step-3) for the hardlink migration to happen. Why?: setfattr operation is an inode based operation. Since, we are doing setfattr from fuse mount here, inode_path will try to build path from the linked dentries to the inode. For a file without hardlinks the path construction will be correct. But for hardlinks, the inode will have multiple dentries linked. Without fresh mount, inode_path will always get the most recently linked dentry. e.g. if there are three hardlinks named dir1/link1, dir2/link2, dir3/link3, on a client where these hardlinks are looked up, inode_path will always return the path dir3/link3 if dir3/link3 was looked up most recently. Hence, we won't be able to create linkto files for all other hardlinks on destination (read gf_defrag_handle_hardlink for more details on hardlink migration). With a fresh mount, the lookup and setfattr become serialized. e.g. link2 won't be looked up until link1 is looked up and migrated. Hence, inode_path will always have the correct path, in this case link1 dentry is picked up(as this is the most recently looked up inode) and the path is built right. Note: If you run the above script on an existing mount(all entries looked up), hard links may not be migrated, but there should not be any other issue. Please raise a bug, if you find any issue.

* nfs/netgroups: do not free the same file twiceMichael Scherer2017-05-291-2/+5
| | | | | | | | | | | | | | | | | | | Coverity warn about a code path where 'file' is freed twice. And reading the code, I also found that 'line' shouldn't be freed using GF_FREE since it was allocated by getline. Also call _ng_deinit_parsers() in the success case, preventing leaking two 'struct parser' upon multiple calls to ng_file_parse().

| | | | | | | | | | | | | | | | | | With object versioning being optional, it can so happen the bitrot stub context is not always set. When it's not found, it's initialized. But was not being assigned to use in the local function. This was leading for brick crash. Fixed the same.

* features/shard: Handle offset in appending writesPranith Kumar K2017-05-271-42/+67
| | | | | | | | | | | | | | | | | | | | | When a file is opened with append, all writes are appended at the end of file irrespective of the offset given in the write syscall. This needs to be considered in shard size update function and also for choosing which shard to write to. At the moment shard piggybacks on queuing from write-behind xlator for ordering of the operations. So if write-behind is disabled and two parallel appending-writes come both of which can increase the file size beyond shard-size the file will be corrupted.
