* features/locks: Clean up logging of cleanup in DISCONNECT codepathKrutika Dhananjay2014-06-114-69/+126
| | | | | | | | | | | | | | | | | | | Now, gfid is printed as opposed to path in cleanup messages. Also, refkeeper update is eliminated in inodelk and entrylk. Instead, the patch ensures inode and pl_inode are kept alive as long as there is atleast one lock (granted/blocked) on an inode. Also, every inode is unref'd appropriately on a DISCONNECT from the lock-owning client.

* feature/changelog: Add timeout to changelog barrier.Kotresh H R2014-06-104-6/+99
| | | | | | | | | | | | | | | | | | | This patch introduces configurable 'changelog-barrier-timeout' in changelog. The default changelog-barrier-timeout is set to 120 sec which is same as barrier-timeout of barrier translator. On this timeout, all the barriered fops are unbarriered. It is safe to have this internal timeout for changelog barrier to prevent it from indefinite barrierring of fops if barrier disable notification does not come from snapshot for some reason.

* features/gfid-access: calloc gfid and set in xdataRavishankar N2014-06-081-5/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: the gfid passed to ga_fill_tmp_loc() was a stack variable which the function set in the xdata dictionary. Accessing it in a later point in time gave unexpected values. This was easy to hit when AFR was involved like so: ga_mknod()--->xxx-->afr_mknod(): In afr_mknod transaction, once the stack-winds for the lock-phase are sent, the gfid in xdata becomes out of scope. When we send the actual op i.e. afr_mknod_wind(), the gfid in xdata is stale, causing posix to set junk gfids on the files. Fix: calloc the gfid and set it in the dict. Thanks to Pranith for the RCA!

* cluster/dht: Fix min-free-disk calculations when quota-deem-statfs is onKrutika Dhananjay2014-06-021-4/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: As part of file creation, DHT sends a statfs call to all of its sub-volumes and expects in return the local space consumption and availability on each one of them. This information is used by DHT to ensure that atleast min-free-disk amount of space is left on each sub-volume in the event that there ARE other sub-volumes with more space available. But when quota-deem-statfs is enabled, quota xlator on every brick unwinds the statfs call with volume-wide consumption of disk space. This leads to miscalculation in min-free-disk algo, thereby misleading DHT at some point, into thinking all sub-volumes have equal available space, in which case DHT keeps sending new file creates to subvol-0, causing it to become 100% full at some point although there ARE other subvols with ample space available. FIX: The fix is to make quota_statfs() behave as if quota xlator weren't enabled, thereby making every brick return only its local consumption and disk space availability.

| | | | | | | | | | | | | | | | | | | | | | | | Problem: Assume the directory structure /quota_limit_dir/subdir and quota_limit_dir is set with some limit. When quota-deem-statfs is enabled the output of 'df /quota_limit_dir' would display quota modified values wrt to quota_limit_dir where as 'df /quota_limit_subdir/subdir' would display the quota modified values wrt volume root (/). This behaviour is not expected since, when mounted with subdirectory admin doesn't want users to know information above the subdirectory mounted. Solution: Any subdirectory within a quota_limit_dir would show the modified values as in the /quota_limit_dir. It searches for the nearest parent that has quota limit set and modifies the statvfs wrt that.

* barrier : fsync call over NFS should be barriered when barrier is enabledAtin Mukherjee2014-05-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | barrier_fsync was not getting hit when fsync call is issued from the application over NFS mount. Investigation reveals that NFS doesn't send an explicit fsync call to the glusterfs server, however NFS converts it with a stable write with O_DSYNC flag, so for a fsync call over NFS mount point, barrier feature always needs to check for writev and its correspoding flags. So to meet all the coditions of write with O_SYNC and fsync getting blocked when barrier is enabled the check has been modified with following: if (!((flags | fd->flags) & (O_SYNC | O_DSYNC))) Point to be noted here is we need to check both fd's flag and the explicit flag as for NFS write fd->flags is 0.

* glusterfs-server : barrier timeout tuning fixAtin Mukherjee2014-04-221-12/+70
| | | | | | | | | | | | | | | | | | | | | | | | | Problem : Reconfiguration of barrier timeout through gluster volume set shows a success but it never changes the default timeout value which is 120 seconds. After digging into the code deeper, it was found that timeout is never modified in reconfigure() as the first check i.e. whether barrier is already enabled or disabled always fails since barrier option is not modified in this request. Fix : Introduced notify() in barrier translator which will take care of the rpc request to enable/disable barrier. reconfigure() will simply set barrier enable/disable and timeout options blindly without any validation. Please note this patch only contains the changes in barrier translator however from complete code flow perspective the caller in the glusterfsd mgmt should call notify instead of reconfigure to fix this problem.
