* open-behind: translator to perform open calls in backgroundAnand Avati2013-02-068-1/+1006
| | | | | | | | | | | | | | | | | | | | This is functionality peeled out of quick-read into a separate translator. Fops which modify the file (where it is required to perform the operation on the true fd) will trigger and wait for the backend open to succeed and use that fd. Fops like fstat() readv() etc. will use anonymous FD (configurable) when original fd is unopened at the backend.

| | | | | | | | | | | | | | | | | | | | The convention followed is that any actor should return non-zero value only if it has not attempted to send the reply back. If an actor returns non-zero, rpcsvc_handle_rpc_call tries to send an error reply. Since, rpcsvc_submit_generic frees the rpc_req, its wrong to invoke it more than once on same rpc_req. When the transport is not connected, rpcsvc_dump used to pass the non-zero value it got from transport to rpcsvc resulting in memory corruption. Hence this patch makes rpcsvc_dump to return 0.

* 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 K2013-02-036-93/+265
| | | | | | | | | | | | | | | | | | | | | | 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.

Instead acquire ref and unref within lock migration function.
