* gfapi: add __THROW [(__attribute) ((__nothrow__))] to fn decls for C++ users.Kaleb S. KEITHLEY2013-12-032-111/+124
| | | | | | | | | | | | | | | | | | Off hand I don't know of anything written in C++ that is or could be a user of gfapi. Never the less, it's possible that one could exist, or be written, and marking the library entry points is a) friendly, b) possibly allows the C++ compiler to generate better code, and c) is a good practice when writing APIs that might be consumed by C++ applications. Considering we already take the first step and use __BEGIN_DECLS/__END_DECLS to be C++ friendly, we should take the extra step Change-Id: Ib319ecaa452a46f258a9c6e8c7221454d2fefd0f Signed-off-by: Kaleb S.

| | | | | | | | | | | | | | | | The logfile fd is not closed even after calling glfs_fini, hence in smb mount if connection to glusterfs volume fails at a point after the log file was opened, the fd would remain open until the process dies.

* glusterfs: zerofill supportM. Mohan Kumar2013-11-102-0/+71
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for a new ZEROFILL fop. Zerofill writes zeroes to a file in the specified range. This fop will be useful when a whole file needs to be initialized with zero (could be useful for zero filled VM disk image provisioning or during scrubbing of VM disk images). Client/application can issue this FOP for zeroing out. Gluster server will zero out required range of bytes ie server offloaded zeroing. In the absence of this fop, client/application has to repetitively issue write (zero) fop to the server, which is very inefficient method because of the overheads involved in RPC calls and acknowledgements. WRITESAME is a SCSI T10 command that takes a block of data as input and writes the same data to other blocks and this write is handled completely within the storage and hence is known as offload . Linux ,now has support for SCSI WRITESAME command which is exposed to the user in the form of BLKZEROOUT ioctl. BD Xlator can exploit BLKZEROOUT ioctl to implement this fop. Thus zeroing out operations can be completely offloaded to the storage device , making it highly efficient. The fop takes two arguments offset and size. It zeroes out 'size' number of bytes in an opened file starting from 'offset' position. This patch adds zerofill support to the following areas: - libglusterfs - io-stats - performance/md-cache,open-behind - quota - cluster/afr,dht,stripe - rpc/xdr - protocol/client,server - io-threads - marker - storage/posix - libgfapi Client applications can exloit this fop by using glfs_zerofill introduced in libgfapi.FUSE support to this fop has not been added as there is no system call for this fop. Changes from previous version 3: * Removed redundant memory failure log messages Changes from previous version 2: * Rebased and fixed build error Changes from previous version 1: * Rebased for latest master TODO : * Add zerofill support to trace xlator * Expose zerofill capability as part of gluster volume info Here is a performance comparison of server offloaded zeofill vs zeroing out using repeated writes. [root@llmvm02 remote]# time ./offloaded aakash-test log 20 real 3m34.155s user 0m0.018s sys 0m0.040s [root@llmvm02 remote]# time ./manually aakash-test log 20 real 4m23.043s user 0m2.197s sys 0m14.457s [root@llmvm02 remote]# time ./offloaded aakash-test log 25; real 4m28.363s user 0m0.021s sys 0m0.025s [root@llmvm02 remote]# time ./manually aakash-test log 25 real 5m34.278s user 0m2.957s sys 0m18.808s The argument log is a file which we want to set for logging purpose and the third argument is size in GB . As we can see there is a performance improvement of around 20% with this fop.

* gfapi: object handle based API extensionsR.Shyamsundar2013-10-1110-25/+2952
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is an ongoing effort to integrate NFS Ganesha ( https://github.com/nfs-ganesha/nfs-ganesha/wiki ) with GlusterFS as one of the file system back ends. Towards this we need extensions to gfapi that can handle object based operations. Meaning, instead of using full paths or relative paths from cwd, it is required that we can work with APIs, like the *at POSIX variants, to be able to create, lookup, open etc. files and directories. Hence the objects are the files or directories themselves and we give out handles to these objects that can be used for further operations. This code drop is an initial implementation of the proposed APIs. The new APIs are implemented as glfs_h_XXX variants in the file glfs-handleops.c to mirror glfs-fops.c style. The code leverages holding onto inode references and doling these out as opaque/cookie type objects to the callers, to enable them to be used as handles in other operations. An fd based approach was considered, but due to the extra footprint that the fd structure and its counterparts would incur, this was dropped to take the approach of holding inode references themselves. Tested by extending glfsxmp.c to invoke and exercise the added APIs, and further tested with a reference integration of the same as an FSAL with NFS Ganesha.

CBKs are required only for the management connection, and the actors of protocol/client are NOP functions. This supposed-to-be NOP function dispatch tabble is actually ending up pointing to the actor table of glusterfsd or gfapi. These functions, even though set wrongly, are not even expected to be called through the protocol/client callback path. Glusterd however sends the FETCHSPEC (and other) notify callbacks to *all* connected clients unconditionally, and there is a small period of time when protocol/client is connected to glusterd for PORTMAP query. If the FETCHSPEC callback notify is issued in this window of time, we end up calling the wrong actor in the client side resulting in a crash.

* log: set ident to openlogBala.FA2013-08-131-1/+2
| | | | | | | | | | | | | | | | | | | | at syslog side, log message is identified by its properties like programname, pid, etc. brick/mount processes need to be identified uniquely as they are different process of gluterfsd/glusterfs. At rsyslog side, log separated by programname/app-name with pid works but bit hard to identify them in long run which process is for what brick/mount. This patch fixes by setting identity string at openlog() which sets programname/app-name as similar to old style log file prefixed by gluster, glusterd, glusterfs or glusterfsd Change-Id: Ia05068943fa67ae1663aaded1444cf84ea648db8 BUG: 928648 Signed-off-by: Bala.FA <barumuga@redhat.com> Reviewed-on: http://review.gluster.org/5541 Reviewed-by: Vijay Bellur <vbellur@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com>

| | | | | | | | | | | | | | | Performing syncop_create() on a pre-existing file can result in opening the linkfile if DHT has a linkfile for the file. This is because dht_create() will perform the op on the hashed_subvol() and overwrite the layout in dht_create_cbk.

Block de-allocation is implemented via fallocate() (as requested via fuse and passed on to the brick fs) but a separate fop is created within gluster to emphasize the fact that discard changes file data (the discarded region is replaced with zeroes) and must invalidate caches where appropriate.

| | | | | | | | | | | | | | | | | | | | Samba opens vfs_gluster.so with dlopen(..,RTLD_LOCAL). This makes the symobls in the shared module and the library it exclusively links against (specifically gfapi) not resolvable from the .so files which are opened in turn within (like xlator .so files) unless explicitly linked against the dependent libraries. This is not otherwise required in case of glusterfsd as the main executable symbols are always available for resolution from dlopen()'ed shared objects, making Samba's vfs_glusterfs requirement unique, but luckily not incompatible.

Instead of performing a wasteful ->lookup() fop for every component in every API call, build in speculation logic to consider the previous resolution result temporarily, and if it results in ESTALE either later in the path resolution or in the FOP, then retry resolution with ->lookup() at every level and retry the FOP. This is the same optimistic resolution/retry logic Linux kernel resolver is proposing to use.
