* afr: serialize modification of {entrylk,inodelk}_lock_countAnand Avati2013-02-071-53/+54
| | | | | | | | | | | | | | Typically this lock was not needed in practice, but with http://review.gluster.org/3842, this code gets executed in multiple threads for different servers and we lose a count. This results in leaked lock and a hang for a future transaction.

* dht: better layout-optimization algorithmJeff Darcy2013-02-072-22/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This method deals with the case where swapping might gain a bigger overlap for the xlator currently under consideration, but sacrifices even more from the xlator we're swapping with. For example: A = 0x00000000 - 0x44444443 (new 0x00000000 - 0x55555554) B = 0x44444444 - 0x77777776 (new 0x55555555 - 0xaaaaaaa9) C = 0x77777777 - 0xffffffff (new 0xaaaaaaaa - 0xffffffff) Here, the new range for B has a bigger overlap with the old C than with the old B (0x33333333 vs. 0x22222222 to be precise) so looking only at that might lead us to swap. However, such a swap turns the new C's overlap from 0x55555556 (vs. old C) to *zero* (vs. old B). In other words, we've gained 0x11111111 for B but lost 0x55555556 for C, so it's a bad idea. The new algorithm accounts for all effects of the swap, so it not only avoids bad swaps but can make some good ones that would have been missed previously. For example, if swapping a range X with a later range Y would not increase the overlap for X we would previously have skipped it even if the swap would increase Y's overlap without affecting X's. This is the normal case when we're adding a new brick (which initially has zero overlap with any old range) so finding more good swaps is probably even more important than avoiding bad ones. Also, the logic in dht_overlap_calc was completely broken before, causing integer overflows instead of providing correct values, so no matter what higher-level algorithm was in place the GIGO effect would have resulted in bad decisions.

* cluster/dht: ignore EEXIST error in mkdir to avoid GFID mismatchAnand Avati2013-02-031-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In dht_mkdir_cbk, EEXIST error is treated like a true error. Because of this the following sequence of events can happen, eventually resulting in GFID mismatch and (and possibly leaked locks and hang, in the presence of replicate.) The issue exists when many clients concurrently attempt creation of directory and subdirectory (e.g mkdir -p /mnt/gluster/dir1/subdir) 0. First mkdir happens by one client on the hashed subvolume. Only one client wins the race. Others racing mkdirs get EEXIST. Yet other "laggers" in the race encounter the just-created directory in lookup() on the hash dir. 1. At least one "lagger" lookup() notices that there are missing directories on other subvolumes (which the "winner" mkdir is yet to create), and starts off self-heal of the directory. 2. At least on some subvolumes, self-heal's mkdir wins the race against the "winner" mkdir and creates the directory first. This causes the "winner" mkdir to experience EEXIST error on those subvolumes. 3. On other subvolumes where "winner" mkdir won the race, self-heal experiences EEXIST error, but self-heal is properly translating that into a success (but mkdir code path is not -- which is the bug.) 4. Both mkdir and self-heal assign hash layouts to the just created directory. But self-heal distributes hash range across N (total) subvolumes, whereas mkdir distributes hash range across N - M (where M is the number of subvolumes where mkdir lost the race). Both the clients "cache" their respective layouts in the near future for all future creates inside them (evidence in logs) 5. During the creation of the subdirectory, two clients race again. Ideally winner performs mkdir() on the hashed subvolume and proceeds to create other dirs, loser experiences EEXIST error on the hashed subvolume and backs off. But in this case, because the two clients have different layout views of the parent directory (because of different hash splits and assignements), the hashed subvolumes for the new directory can end up being different. Therefore, both clients now win the race (they were never fighting against each other on a common server), assigning different GFIDs to the directory on their respective (different) subvolumes. Some of the remaining subvolumes get GFID1, others GFID2. Conclusion/Fix: Making mkdir translate EEXIST error as success (just the way self-heal is already rightly doing) will bring back truth to the design claim that concurrent mkdir/self-heals perform deterministic + idempotent operations. This will prevent the differing "hash views" by different clients and thereby also avoid GFID mismatch by forcing all clients to have a "fair race", because the hashed subvolume for all will be the same (and thereby avoiding leaked locks and hangs.)

* protocol/client: Periodically attempt reopensPranith Kumar K2013-02-035-93/+263
| | | | | | | | | | | | | | | | | | | | | | If the brick is taken down and the hard disk is replaced and the brick is brought back up, the re-opens of the open-fds will fail because the file is not present on the brick. Re-opens are not attempted even if the files are re-created by self-heal until the brick is brought down after the files are re-created and brought back up. This is a problem with a VM-store in a replica-setup. Until the fd is re-opened the writes will never happen on the brick where the hard-disk is replaced. To handle this situation gracefully, client xlator is enhanced to perform finodelk, fxattrop, writev, readv using anonymous fds if the file is yet to be re-opened. If the fop succeeds then client xlator attempts re-open.

* cluster/afr: if a subvolume is down wind the lock request to nextRaghavendra Bhat2013-01-291-15/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | When one of the subvolume is down, then lock request is not attempted on that subvolume and move on to the next subvolume. /* skip over children that are down */ while ((child_index < priv->child_count) && !local->child_up[child_index]) child_index++; In the above case if there are 2 subvolumes and 2nd subvolume is down (subvolume 1 from afr's view), then after attempting lock on 1st child (i.e subvolume 0) child index is calculated to be 1. But since the 2nd child is down child_index is incremented to 2 as per the above logic and lock request is STACK_WINDed to the child with child_index 2. Since there are only 2 children for afr the child (i.e the xlator_t pointer) for child_index will be NULL. The process crashes when it dereference the NULL xlator object.

| | | | | | | | | | | | | | | | | | Generally inode-write fops do transaction.unwind then transaction.resume, but writev needs to make sure that delayed post-op frame is placed in fdctx before unwind happens. This prevents the race of flush doing the changelog wakeup first in fuse thread and then this writev placing its delayed post-op frame in fdctx. This helps flush make sure all the delayed post-ops are completed.
