* posix: add a simple health-checkerNiels de Vos2013-07-035-0/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Goal of this health-checker is to detect fatal issues of the underlying storage that is used for exporting a brick. The current implementation requires the filesystem to detect the storage error, after which it will notify the parent xlators and exit the glusterfsd (brick) process to prevent further troubles. The interval the health-check runs can be configured per volume with the storage.health-check-interval option. The default interval is 30 seconds. It is not trivial to write an automated test-case with the current prove-framework. These are the manual steps that can be done to verify the functionality: - setup a Logical Volume (/dev/bz970960/xfs) and format is as XFS for brick usage - create a volume with the one brick # gluster volume create failing_xfs glufs1:/bricks/failing_xfs/data # gluster volume start failing_xfs - mount the volume and verify the functionality - make the storage fail (use device-mapper, or pull disks) # dmsetup table .. bz970960-xfs: 0 196608 linear 7:0 2048 # echo 0 196608 error > dmsetup-error-target # dmsetup load bz970960-xfs dmsetup-error-target # dmsetup resume bz970960-xfs # dmsetup table ... bz970960-xfs: 0 196608 error - notice the errors caught by syslog: Jun 24 11:31:49 vm130-32 kernel: XFS (dm-2): metadata I/O error: block 0x0 ("xfs_buf_iodone_callbacks") error 5 buf count 512 Jun 24 11:31:49 vm130-32 kernel: XFS (dm-2): I/O Error Detected.

* cluster/afr: Let two data-self-heals compete in new domainPranith Kumar K2013-07-034-23/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: At the moment data-self-heal acquires locks in following pattern. It takes full file lock then gets xattrs on files on both replicas. Decides sources/sinks based on the xattrs. Now it acquires lock from 0-128k then unlocks the full file lock. Syncs 0-128k range from source to sink now acquires lock 128k+1 till 256k then unlocks 0-128k, syncs 128k+1 till 256k block... so on finally it takes full file lock again then unlocks the final small range block. It decrements pending counts and then unlocks the full file lock. This pattern of locks is chosen to avoid more than 1 self-heal to be in progress. BUT if another self-heal tries to take a full file lock while a self-heal is already in progress it will be put in blocked queue, further inodelks from writes by the application will also be put in blocked queue because of the way locks xlator grants inodelks. So until the self-heal is complete writes are blocked. Here is the code: xlators/features/locks/src/inodelk.c - line 225 if (__blocked_lock_conflict (dom, lock) && !(__owner_has_lock (dom, lock))) { ret = -EAGAIN; if (can_block == 0) goto out; gettimeofday (&lock->blkd_time, NULL); list_add_tail (&lock->blocked_locks, &dom->blocked_inodelks); } This leads to hangs in applications. Fix: Since we want to prevent two parallel self-heals. We let them compete in a separate "domain". Lets call the domain on which the locks have been taken on in previous approach as "data-domain". In the new approach When a self-heal is triggered, it acquires a full lock in the new domain "self-heal-domain". After this it performs data-self-heal using the locks in "data-domain" as before. unlock the full file lock in "self-heal-domain" With this approach, application's writevs don't have to wait in pending queue when more than 1 self-heal is triggered.

| | | | | | | | | | | | | | | | | | - afr_local_copy should not be memduping locked nodes, that would mean that lock is taken in self-heal on those nodes even before it actually takes the lock. So removed memdup code. Even entry lock related copying (lockee info) is also not necessary for self-heal functionality, so removing that as well. Since it is not local_copy anymore changed its name. - My editor changed tabs to spaces.

* cluster/afr: post-op should complete before starting flushPranith Kumar K2013-07-033-36/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: At the moment afr-flush makes sure that a delayed post-op is woken up but it does not wait for it to complete the post-op before flush unwinds. These are the steps that are happening: 1) flush fop comes on an fd which wakes up a delayed post-op and continues with the flush fop. 2) post-op sends fsync on the wire. 3) flush completes and unwinds to fuse. 4) graph switch happens on the fuse mount disconnecting the old graph's client connections to bricks. 5) xattrop after fsync fails with ENOTCONN because the connections from old graph are taken down now. Fix: Wait for post-op to complete before starting to flush. We could make flush act similar to fsync (i.e.) wind flush as is but wait for post-op to complete before unwinding flush, but it is better to send flush as the final fop. So wind of flush will start after post-op is complete. Had to change fsync to accommodate this change.

* cluster/afr: Allow data/entry self heal for metadata split-brainVenkatesh Somyajulu2013-07-029-134/+285
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Currently whenever there is metadata split-brain, a variable sh->op_failed is set to 1 to denote that self heal got failed. But if we proceed for data self heal, even code-path of data self heal also relies on the sh->op_failed variable. So if will check for sh->op_failed variable and will eventually fails to do data self heal. So needed a mechanism to allow data self heal even if metadata is in split brain. Fix: Some data structure revamp is done in http://review.gluster.com/#/c/5106/ fix and this patch is based on the above fix. Now we can store which particular self-heal got failed i.e GFID_OR_MISSING_ENTRY_SELF_HEAL, METADATA, DATA, ENTRY. And we can do two types of self heal failure check. 1. Individual type check: We can check which among all four (Metadata, Data, Gfid or missing entry, entry self heal) got failed. 2. In afr_self_heal_completion_cbk, we need to make check based on the fact that if any specific self heal got failed treat the complete self heal as failure so that it will populate corresponding circular buffer of event history accordingly.

Fix: Perform changelog wakeup on anon-fd if the fd with same pid is not present in inode-list. Note: This approach is a short-term fix. A proper fix needs a new domain for taking metadata locks so that data/metadata locks don't compete with each other.

* glusterd: Disable transport before cleaning up rpc objectKrishnan Parthasarathi2013-06-183-19/+99
| | | | | | | | | | | | | | | | | | | | | | | | | Problem: rpc_transport object, which is part of rpc_clnt, is destroyed prematurely. This is because, rpc_transport object is ref'd by socket layer and rpc layer. These ref's, until the synctask'izing of operations, were unref'd sequentially in the epoll thread. With more threads at play, the sequential unref guarantee is off. Fix: Shutting down the transport before proceeding with cleaning up of rpc_clnt object would serialize the unref's on the rpc_transport object and thus eliminating the race. Also, we don't store the address of brickinfo in brick's rpc notify function, to avoid the possibility of referring a freed brickinfo. Instead we use a string based id to 'reach' the corresponding brickinfo.

| | | | | | | | | | | | | | | | | | | | | | | | | While looking at the newly introduced procedures FALLOCATE and DISCARD, it seems that these were added with already existing procedure numbers. This makes the protocol incompatible with existing roll-outs. It is very confusing when new procedures are added somewhere in the middle of the array. This will cause the number of existing procedures to change. It is much preferred to add new procedures at the end of the array. This changes not only corrects the enum that generates the procedure numbers, but also the ordering in the client and server fops-array for clarity. Correcting this greatly simplifies adding support for these new procedures in Wireshark and will prevent confusion to the people reading network traces (with or without Wireshark).

To ensure this, on rpc_clnt's last unref, we cleanup the corresponding rpc_transport object and complete the rpc_clnt cleanup later, in a bottom-up fashion. Introduced rpc_clnt_is_disabled, to allow higher layers to differentiate between the 'final'[1] disconnect triggered from upper layers, and a normal disconnect. This differentiation helps in cleaning up resources, at higher layers, in a race-free manner. [1] - 'final' here means that the rpc and the associated connection, is not going to be used anymore. eg - glusterd_brick_disconnect on volume-stop.
