* Do not failover readdir in replicateAnand Avati2009-07-171-34/+18
| | | | | | | | | | | | Backport of http://patches.gluster.com/patch/561/ to release-2.0 Also, the failover version of afr_readdir_cbk is buggy and crashes when it is called after a failover inevitably Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 150 (AFR readdir should not failover to other subvolume) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=150
* server: don't check for 'loc->parent' in entrylk and inodelk callsAmar Tumballi2009-07-171-4/+2
| | | | | | | | | | | | the lock operation on entry or inode is going to happen on only one inode, and it doesn't need dentry (with info on parent) for the lock operation to complete. Hence, in server_{inode,entry}lk() calls after server_loc_fill, we -should not- be checking for parent inode. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 112 (parallel deletion of files mounted by different clients on the same back-end hangs and/or does not completely delete) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=112

* Add a random initial offset to the afr round robin indexErick Tryzelaar2009-07-161-0/+3
| | | | | | | | | | | | | | | This patch helps to distribute load across an afr cluster when you have clients with the same access patterns, such as in benchmarking or map-reduce. By randomly offsetting the initial read_child_rr, clients should distribute reads over the afr nodes on average. A better solution could be to randomly shuffle the children instead of chosing a different initial offset. This should average the reads better across the nodes, but I'm not sure if there are any other consequences to doing this. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* fuse-bridge: Export user.glusterfs-booster-mount xattrShehjar Tikoo2009-07-161-0/+3
| | | | | | | | | | | | | | | This needs to be exported in order to have the booster Mount Point Bypass technique work through libglusterfsclient. Booster uses the mount point to register with libglusterfsclient as a VMP. Subsequently, all file operations on the mounted GlusterFS mount point get redirected to libglusterfsclient. This fixes bug 136. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 136 (booster does not redirect ops on GlusterFS mount point into libglusterfsclient) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=136

| | | | | | | | | | | | | | | | each of the subvolume - This patch fixes bug #29. - Using separate copies of dictionaries also eliminates a potential bug in a setup consisting of afr with a posix and client, each having io-threads on top as children. Since posix_xattrop after performing required operations on the xattr array passed in dictionary, sets the result at the same key and in the same dictionary passed as input argument, there can be race conditions where in the results of the operation on posix-child can be sent to the other child as input argument for xattrop, which ofcourse is wrong.

* io-cache: prevent frames from getting woken up while page is getting validatedAnand Avati2009-06-031-1/+1
| | | | | | | | | | | | | | | | 1. A page will be put on the inode waitq if the 'freshness' has to be verified with an fstat() 2. while the fstat is in transit, other calls (like lookup) can update ioc_inode->tv, resetting the freshness (page still on inode waitq) 3. Another read request on the same page, after the updated freshness, will wake up the page frames neglecting the fact that the page is also waiting on the inode (waiting for the fstat completion) 4. once the page's frames are woken, the page becomes elegible for purging and can get destroyed for various reasons, leaving a destroyed page pointer in the inode's waitq 5. fstat returns and hits the destroyed page pointer causing a crash The fix is to all together disable cache hits when any page of the same inode is under validation. The otherwise cache hit will now be subjected to the ongoing validation by getting queued to the inode waitq. Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* unify getdents count reduced to 512 (from 1024)Amar Tumballi2009-06-031-1/+1
| | | | | | | | | | | | Thanks to Krishna <krishna (at) gluster.com> for pointing this out. When a unify self-heal of large directory (directory with lot of entries) is done, the getdents_cbk used to fail because of new limit of buffer size (128KB). Noticed that earlier it used to streach upto 4MB, hence the value 1024 worked fine. By reducing it to 512, noticed, we can fit in well within 128KB limit, and hence unify self-heal goes through.
