* fuse-bridge: Handle graph-switch.Raghavendra G2012-02-215-75/+522
| | | | | | | | | | | | | | | | | The purpose of this patch is to let protocol/client know when its transports can be disconnected, without application running on gluster mount noticing any effects of graph switch. In order to do this, we migrate all fds and blocked locks to new graph. Once this migration is complete and there are no in-transit frames as viewed by fuse-bridge, we send a PARENT_DOWN event to its children. protocol/client on receiving this event, can disconnect up its transports.

* protocol/client,server: fcntl lock self healing.Mohammed Junaid2012-02-201-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently(with out this patch), on a disconnect the server cleans up the transport which inturn closes the fd's and releases the locks acquired on those fd's by that client. On a reconnect, client just reopens the fd's but doesn't reacquire the locks. The application that had previously acquired the locks still is under the assumption that it is the owner of those locks which might have been granted to other clients(if they request) by the server leading to data corruption. This patch allows the client to reacquire the fcntl locks (held on the fd's) during client-server handshake. * The server identifies the client via process-uuid-xl (which is a combination of uuid and client-protocol name, it is assumed to be unique) and lk-version number. * The client maintains a list of process-uuid-xl, lk-version pair for each accepted connection. On a connect, the server traverses the list for a matching pair, if a matching pair is not found the the server returns lk-version with value 0, else it returns the lk-version it has in store. * On a disconnect, the server and client enter grace period, and on the completion of the grace period, the client bumps up its lk-version number (which means, it will reacquire the locks the next time) and the server will distroy the connection. If reconnection happens within the grace period, the server will find the matching (process-uuid-xl, lk-version) pair in its list which guarantees that the fd's and there corresponding locks are still valid for this client. Configurable options: To set grace-timeout, the following options are option server.grace-timeout value option client.grace-timeout value To enable or disable the lk-heal, option lk-heal [on|off] gluster volume set command can be used to configurable options Change-Id: Id677ef1087b300d649f278b8b2aa0d94eae85ed2 BUG: 795386 Signed-off-by: Mohammed Junaid <junaid@redhat.com> Reviewed-on: http://review.gluster.com/2766 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>

* core: GFID filehandle based backend and anonymous FDsAnand Avati2012-01-204-296/+127
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | FUSE used to interpret the umask itself. That was a bad idea, since there are cases where umask is not applied, such as when extended POSIX ACLs are present and default ACLs are set on parent directory. Thus, FUSE was changed to pass umask to operation handler itself in case the fuse server is initialized with FUSE_DONT_MASK. In case FUSE supports it, gluster client sends mode unmasked and umask separately ( masked mode is still sent, for compatibility with old servers). the mode as-is for compatibility with older clients.

* glusterfsd: enable max fetch attemptsKaushal M2011-09-181-1/+7
| | | | | | | | | | | | | | Enables usage of 'volfile-max-fetch-attempts' option of glusterfsd. Also, adds an option to 'mount.glusterfs' for setting the max fetch attempts. For a server with multiple ips, each call to gf_resolve_ip6() returns a different ip. Since gf_resolve_ip6() is called for each fetch attempt, this change also enables rrdns support for gluster.

User can be given in numeric form, in which case it's treated as an uid directly, or else it's tried to be resolved to an uid with getpwnam(3). Implies --acl.

* fuse-resolve: prevent linking of inodes of different inode-tableAmar Tumballi2011-08-101-25/+31
| | | | | | | | | | | | | | | | | | This can happen in deep_resolve_cbk, which happens after a graph switch. Root cause was because the graph change happened while a FOP was in transit and by the time the call came back, the active translator of fuse is now changed. Fix is to make sure the resolve operation happens on a given inode table, instead of taking the latest graph of fuse for each operation Change-Id: Idd6e2d5c2d5fc5d571f7a1fbc174e210babf8a2b BUG: 3355 Reviewed-on: http://review.gluster.com/195 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Shishir Gowda <shishirng@gluster.com> Reviewed-by: Anand Avati <avati@gluster.com>
