* gNFS: RFE for NFS connection behaviorSantosh Kumar Pradhan2013-11-141-0/+14
| | | | | | | | | | | | | | | Implement reconfigure() for NFS xlator so that volume set/reset wont restart the NFS server process. But few options can not be reconfigured dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be restarted.

* gNFS: NFS segfaults with nfstest_posix toolSantosh Kumar Pradhan2013-11-041-0/+4
| | | | | | | | | | | | | | | | | | | | | | Problem: nfs3_stat_to_fattr3() missed a NULL check. FIX: (1) Added a NULL check. (2) In all fop cbk path, if the op_ret is -1 and op_errno is 0, then handle it as a special case. Set the NFS3 status as NFS3ERR_SERVERFAULT instead of NFS3_OK. (3) The other component of FIX would be in DHT module and is on the way.

* gNFS: NFS daemon is limiting IOs to 64KBSantosh Kumar Pradhan2013-09-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Problem: Gluster NFS server is hard-coding the max rsize/wsize to 64KB which is very less for NFS running over 10GE NIC. The existing options nfs.read-size, nfs.write-size are not working as expected. FIX: Make the options nfs.read-size (for rsize) and nfs.write-size (for wsize) work to tune the NFS I/O size. Value range would be 4KB(Min)-64KB(Default)-1MB(max). NB: Credit to "Richard Wareing" for catching it.

* nfs3: Resolve entry vs. hash conflict at same dir depthShehjar Tikoo2011-09-071-15/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intro Note ========== The current code in hard fh resolution takes the first-match approach, i.e. which ever dirent either matches the hash or matches the gfid first is the one chosen as the result for the next step of fh resolution. In the latter case, i.e., dirent matches the gfid, we the next step is to conclude the fh resolution by returning the entry whose gfid matched. In the former, i.e., the hash matches the dirent, we choose the hash-matching dirent as the next directory to descend into, for searching the file to be operated upon. Problem ======= When performing hard fh resolution, there can be a situation where: o the hash of the primary entry,i.e. the entry we're looking for and the hash of another sibling directory, match. Note the use of "sibling", meaning both the primary entry and the hash matching one are in the same directory, i.e., their filehandle.hashcount will be same. o the sibling directory is encountered first during the dir search. Because of the current code described in "Intro", we'll end up descending into the sibling directory even though the correct behaviour is to ignore this and wait till we encounter the primary entry in the same parent directory. Once we end up descending into this sibling directory, the directory depth validation check fails. The check fails because it notices that the resolution is attempting to open a directory that is deeper in the fs tree than the file we're looking for. When this check fails, we return an ESTALE. So basically, a false-positive results in an estale to Specsfs. This is not a theoretical situation. Me and Avati saw this on specsfs test where sfs created terabytes-sized file system for its tests. The number of files was so huge in a single directory that the hashes of two entries ended up colliding.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revert "nfs3: Unref & unbind dir fd with inode lock on EOF" This reverts commit 4e6fb304ce41acbaf7c9ba67c06bf443e65082e8. The above commit (which unbinds fds at EOF) does not fix the original bug (1619) because a readdir from a second app could have already started before the readdir_cbk of the first app's readdir reaches NFS code. Hence the race still exists. Performing extra unrefs when EOF is received is not a reliable way of detecting that a client has performed a closedir (and to close the fd ourselves). Neither is interpreting a 0 cookies a new opendir. Clients can always use telldir/seekdir and hit EOFs twice. Due to the way NFS3 protocol is designed, it is just not possible for the server to reliably detect opendirs/closedirs performed by the client and map the corresponding readdirs to the same dir fd on the server side. The only reliable way of fixing this is to perform opendir/closedir at the cost of performance. Any optimization towards keeping dir fds open attempting to map them with application's opendir/closedir will either result in fd leaks or extra fd unrefs. Signed-off-by: Anand V.

* gfid: changes in inode managementAnand Avati2010-09-041-3/+0
| | | | | | | | | | | | | - incorporate usage of uuid (gfid) as the key for finding inodes - deprecate inode number/generation number based inode_get - undo code specific to generation numbers (attic list etc.) Signed-off-by: Anand V.

* nfs3: Return ESTALE when going beyond fh-hashcount or max-hashesShehjar Tikoo2010-08-311-7/+40
| | | | | | | | | | | | During fh resolution, if we go beyond the max hashes support by gnfs or if we go beyond the dir depth specified in the filehandle, then return ESTALE.

* nfs3: Unref dir fd once usage ends in hard fh resolutionShehjar Tikoo2010-08-311-3/+29
| | | | | | | | | | | | | | | | | | There are three conditions when a dir fd_t needs to be unrefed when: a. the inode being searched is found as the candidate entry, b. we have exhausted all the entries in the current dir, c. we decide to step into a child directory because of a hash match. This decision is made in nfs3_fh_resolve_check_response.
