* core: utilize mempool for frame->local allocationsAmar Tumballi2012-02-211-9/+9
| | | | | | | | | | | | | | | in each translator, which uses 'frame->local', we are using GF_CALLOC/GF_FREE, which would be costly considering the number of allocation happening in a lifetime of 'fop'. It would be good to utilize the mem pool framework for xlator's local structures, so there is no allocation overhead.

* core: GFID filehandle based backend and anonymous FDsAnand Avati2012-01-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. What -------- This change introduces an infrastructure change in the filesystem which lets filesystem operation address objects (inodes) just by its GFID. Thus far GFID has been a unique identifier of a user-visible inode. But in terms of addressability the only mechanism thus far has been the backend filesystem path, which could be derived from the GFID only if it was cached in the inode table along with the entire set of dentry ancestry leading up to the root. This change essentially decouples addressability from the namespace. It is no more necessary to be aware of the parent directory to address a file or directory. 2. Why ------- The biggest use case for such a feature is NFS for generating persistent filehandles. So far the technique for generating filehandles in NFS has been to encode path components so that the appropriate inode_t can be repopulated into the inode table by means of a recursive lookup of each component top-down. Another use case is the ability to perform more intelligent self-healing and rebalancing of inodes with hardlinks and also to detect renames. A derived feature from GFID filehandles is anonymous FDs. An anonymous FD is an internal USABLE "fd_t" which does not map to a user opened file descriptor or to an internal ->open()'d fd. The ability to address a file by the GFID eliminates the need to have a persistent ->open()'d fd for the purpose of avoiding the namespace. This improves NFS read/write performance significantly eliminating open/close calls and also fixes some of today's limitations (like keeping an FD open longer than necessary resulting in disk space leakage) 3. How ------- At each storage/posix translator level, every file is hardlinked inside a hidden .glusterfs directory (under the top level export) with the name as the ascii-encoded standard UUID format string. For reasons of performance and scalability there is a two-tier classification of those hardlinks under directories with the initial parts of the UUID string as the directory names. For directories (which cannot be hardlinked), the approach is to use a symlink which dereferences the parent GFID path along with basename of the directory. The parent GFID dereference will in turn be a dereference of the grandparent with the parent's basename, and so on recursively up to the root export. 4. Development --------------- 4a. To leverage the ability to address an inode by its GFID, the technique is to perform a "nameless lookup". This means, to populate a loc_t structure as: loc_t { pargfid: NULL parent: NULL name: NULL path: NULL gfid: GFID to be looked up [out parameter] inode: inode_new () result [in parameter] } and performing such lookup will return in its callback an inode_t populated with the right contexts and a struct iatt which can be used to perform an inode_link () on the inode (without a parent and basename). The inode will now be hashed and linked in the inode table and findable via inode_find(). A fundamental change moving forward is that the primary fields in a loc_t structure are now going to be (pargfid, name) and (gfid) depending on the kind of FOP. So far path had been the primary field for operations. The remaining fields only serve as hints/helpers. 4b. If read/write is to be performed on an inode_t, the approach so far has been to: fd_create(), STACK_WIND(open, fd), fd_bind (in callback) and then perform STACK_WIND(read, fd) etc. With anonymous fds now you can do fd_anonymous (inode), STACK_WIND (read, fd). This results in great boost in performance in the inbuilt NFS server. 5. Misc ------- The inode_ctx_put[2] has been renamed to inode_ctx_set[2] to be consistent with the rest of the codebase.

* cluster/afr: Make local->child_up immutablePranith Kumar K2011-09-211-35/+21
| | | | | | | | | | | | | | | | | | | | | | | Afr transaction performs lock, pre-op, op, post-op and unlock steps in that order. The child_up[] is overloaded with the information of where all the first two steps succeeded. This works perfectly fine for Transaction, but the locking/unlocking part of the code is re-used by data self-heal. In that each loop_frame does lock, rchecksum, read-from-source and write-to-sinks, unlock steps. Rchecksum fop assumes that the fop needs to happen on one source + all sinks and sets the call_count to that number. But if the lock step fails on any of the sinks it will mark the child_up of that child to 0, which will result in call_count mismatch and the frame will hang thinking that some more cbks need to come. When this happens loop_frame will never go to unlock step leading to hangs on that file.

* cluster/afr: Make data selfheal trigger to be configurable.Pranith Kumar K2011-09-081-12/+10
| | | | | | | | | | | | | | | | | | | | By default, lookup triggers data self-heal but that is not the preferred way of operating replicated volumes. We would like the data self heals to be triggered in open instead. Number of back-ground self-heals allowed is 16 and lookups block until self-heal is completed. We want to prevent blocking in fops. We can not make lookups independent of self-heal frames because when there are gfid conflicts the decision of which file is correct is determined in self-heal phase. So in afr, lookup self-heal is going to guarantee name space consistency and open/fd fops will take responsibility for data consistency, these are non blocking. The user needs to set the option cluster.data-self-heal "open" for this behavior.

* replicate: Set setxattr wait-count to child-count to avoid raceShehjar Tikoo2010-07-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | A race is seen during a compilebench load against NFS where a NFSv3 MKDIR is immediately followed by a LOOKUP on the new directory. By the time this lookup comes in, the setxattr issued by distribute for the mkdir has not returned yet from all the replicas. Since replicate returns a reply for setxattr after receiving reply only from one subvol, the MKDIR is unwound from distribute. When the LOOKUP is received at distribute, the setxattr has still not completed at the second replica, whereas that is where the lookup is sent by replicate. Finding that the xattr is missing from the dir, distribute returns ESTALE to NFS, which return NFS3ERR_STALE to nfs client. This patch changes replicate setxattr behaviour by forcing replicate to wait for all children rather than one to call back before unwinding the stack.

| | | | | | | | | | | | | | | | | | | | | | | This patch brings in partial support for self-heal of open fds. The precondition is that the fd should have been opened successfully during the initial open() (or create()), and we assume that protocol/client has successfully reopened the fd when the subvolume comes back up. It works by doing an "up/down flush" (a dummy flush transaction to do post-op wherever necessary) and then triggering data self-heal on the file in the post-post-op hook of the dummy flush transaction. This ensures that any writes that come in during self-heal will wait until self-heal completes. The up/down flush is also done when a subvolume goes down, so that post-op is done on all subvolumes where pre-op was done. Signed-off-by: Vikas Gorur <vikas@gluster.com> Signed-off-by: Anand V.
