* geo-rep: logrotate: Logrotate handlingAravinda VK2013-10-035-17/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In existing georep logrotate was implemented by handling SIGSTOP and SIGCONT, gsyncd was failing to start again after SIGSTOP. New approach uses WatchedFileHandler in logging, which tracks the log file changes or logrotate. Reopens the log file if logrotate is triggered or if same log file is updated from other process. As per python doc: http://docs.python.org/2/library/logging.handlers.html: The WatchedFileHandler class, located in the logging.handlers module, is a FileHandler which watches the file it is logging to. If the file changes, it is closed and reopened using the file name. A file change can happen because of usage of programs such as newsyslog and logrotate which perform log file rotation. This handler, intended for use under Unix/Linux, watches the file to see if it has changed since the last emit. (A file is deemed to have changed if its device or inode have changed.) If the file has changed, the old file stream is closed, and the file opened to get a new stream.

* glusterd: Calculate volume op-versions only on set/resetKaushal M2013-09-293-6/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The volume op-versions are calculated during a volume set/reset, reading a volume from disk and importing a volume during probe or volume sync. The calculation of the volume op-version depends on the clusters op-version as some features are enabled automatically depending on the clusters op-version. We also don't store the volume op-versions persistently and don't export the volume op-versions during sync. Due to this, there can occur cases which will lead to inconsistencies in volumes in different peers. One such case is below, Consider, a cluster made up 3 peers P1, P2 and P3, operating at op-version N. The cluster has two volumes V1 and V2, which have volume op-versions N (since volume op-version cannot be greater than cluster op-version). We have, Cluster-op-version = N V1 op-version = N V2 op-version = N A set operation on V1 causes the clusters op-version to be bumped up to N+1. Assume that there exist some features that are automatically enabled on op-version N+1. The op-version of V2 remains at N as no operation has been performed on it. So, Cluster op-version = N+1 V1 op-version = N+1 V2 op-version = N Now, we probe a new peer P4. On the new peer we will have the following op-versions, Cluster op-version = N+1 V1 op-version = N+1 V2 op-version = N+1 This happens because we don't send volume op-versions during the sync after probe. P4 will freshly calculate the op-version of V2 (assuming features have been auto enabled due to the cluster op-version being N+1) as N+1. Another case is when glusterd on a peer restarts. Assume P3 was restarted, glusterd will recalculate the volume op-versions during the restore state. Again, op-version of V2 will be calculated as N+1 assuming auto enabled features. This will lead to inconsistency in the volume representation in memory and on disk, as glusterd will assume the volume contains auto enabled features, but the volfiles don't contain them as they were not regenrated. These kind of issues can be solved by calculating the volume op-version only when features are enabled and disabled (ie. during volume set/reset), persisting the volume-op-versions and exporting/importing them.

When setting a global option, like 'nfs.*' options, glusterd used to modify the volinfo for all the volumes, but would store only the volinfo for the named volume. This lead to mismatch in the persisted and the in-memory representation of those volumes, which lead to problems like peers being rejected because of volume mismatches.

| | | | | | | | | | | | | | | | | | | | | | | | Problem: Incorrect NFS ACL encoding causes "system.posix_acl_default" setxattr failure on bricks on XFS file system. XFS (potentially others?) doesn't understand when the 0x10 prefix is added to the ACL type field for default ACLs (which the Linux NFS client adds) which causes setfacl()->setxattr() to fail silently. NFS client adds NFS_ACL_DEFAULT(0x1000) for default ACL. FIX: Mask the prefix (added by NFS client) OFF, so the setfacl is not rejected when it hits the FS.

* glusterd: Adding transaction checks for cluster unlock.Avra Sengupta2013-09-201-3/+12
| | | | | | | | | | | | | | | | | | | | | | While a gluster command holding lock is in execution, any other gluster command which tries to run will fail to acquire the lock. As a result command#2 will follow the cleanup code flow, which also includes unlocking the held locks. As both the commands are run from the same node, command#2 will end up releasing the locks held by command#1 even before command#1 reaches completion. Now we call the unlock routine in the code path, of the cluster has been locked during the same transaction.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | Earlier disk space check had an issue which didn't provide the needed functionality to avoid migration when the destination had lesser available space, scenario we need to avoid is stated below : During rebalance `migrate-data` - Destination subvol experiences a `reduction` in 'blocks' of free space, at the same time source subvol gains certain 'blocks' of free space. A valid check is necessary here to avoid errorneous move to destination where the space could be scantily available. This patch provides a proper fix in place by subtracting necessary file blocks from destination and adding those blocks to source.

| | | | | | | | | | | | | | | | | | | | The rebalance status was being reset to 'Not started' when add-brick was performed. This would lead to odd cases where a 'rebalance status' on a volume would show status as 'not started' but would also include the rebalance statistics. This also affected the showing of asynchronus task status in 'volume status' command. By not resetting the status prevent the above issues from happening. Since we use the running/not-running of the rebalance process as the check when performing other operations we can safely leave the rebalance stats collected on an add-brick.

Checking for inode utilization on dst relative to src is of no use because dst is already storing linkfile and inode is already consumed no matter what. We might as well perform the rebalance and save on an inode on the src node.
