* glusterd: Changed op_sm_queue locking mechanism to accomodate nested calls ↵Krishnan Parthasarathi2012-02-031-1/+8
| | | | | | | | | | | | | | | | | | | | | | | to op_sm Today if an rpc call made inside an op_sm can fail due to a disconnected peer, resulting in the rpc callback to be called in the same stack with appropriate status set. All glusterd rpc cbks move the state machine based on the status returned by the rpc layer, which would result in a nested call to op_sm. With the current scheme of locking, glusterd would end up in a deadlock situation The new scheme will fail the nested glusterd_op_sm (). This prevents the deadlock. It would work without any change in overall behaviour, as the current op_sm () call in execution wouldn't return until all events in the queue are processed.

This patch makes sure that xattrop is done for all the afr subvol keys after a new entry is created in entry-self-heal. 1) Added matrix create/cleanup functions 2) Impunging a new file does multiple xattrops on the source subvol, one per sink. The code can do a single xattrop after the entry is created on all the sinks. 3) Missing entry self-heal uses one frame per sink to heal the file. This leads to multiple xattrops on the source subvol. That code is changed now to use one frame which will create the file on all subvols.

No other patches can be uploaded without a build failure now.

| | | | | | | | | | | | | | | | | | | * the trusted.glusterfs.pump.{start|pause|commit|status|abort} xattrs have been moved out of trusted domain. This enables separation of xattrs used as gluster-internal commands (handled by pump) for replace-brick, which are not set in the back-end, from xattrs set on the replace-brick source and destinations bricks. * macros definitions from pump.h and glusterd.h, #defining these xattrs have been merged and put into libglusterfs/src/glusterfs.h Change-Id: I87b8bfbf045aa140f5d3f0c9baa9b2e79f87b67b BUG: 783049 Signed-off-by: Rajesh Amaravathi <rajesh@redhat.com> Reviewed-on: http://review.gluster.com/2663 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Amar Tumballi <amar@gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>

* core: GFID filehandle based backend and anonymous FDsAnand Avati2012-01-2030-1445/+2183
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
