* gNFS: avoid double fd unref in opendirSantosh Kumar Pradhan2013-09-241-3/+1
| | | | | | | | | | | | | | | | Noticed that the fd_unref was called on the fd regardless of the return value at nfs3svc_opendir_readdir_cbk(), hence removing an extra unref in the negative case in nfs_inode_opendir_cbk, which fixes the spurious fd_unref().

* glusterd: Don't reset rebalance status on add-brickKaushal M2013-09-191-9/+0
| | | | | | | | | | | | | | | | | | | | | | Backport of 67c28b19355c47e96d1420405cc38753a3e5f9be from master 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.

* glusterd: Calculate volume op-versions only on set/resetv3.4.1qa2Kaushal M2013-09-133-6/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/5568 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.

| | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/5715 Earlier, a peer running a higher op-version couldn't be probed into a cluster running at a lower op-version. This created issues when trying to expand an upgraded cluster. This patch changes this behaviour. The cluster no longer rejects a peer being probed if its op-version is higher than the cluster op-version. The peer will reduce its op-version if it doesn't have any volumes. If the peer contains volumes and needs to reduce its op-version, it fails the handshake and the probe fails.

* cluster/dht: assign layout onto missing directories tooAnand Avati2013-09-101-4/+28
| | | | | | | | | | | | | | | | | | | | | | | | The current self-healing algorithm is ignoring missing directories for assigning new layout. When lookup() is racing against mkdir() or when self-healing a half-done mkdir(), the layout assignment split must happen based on the final number of directories, and not the currently existing number of directories (because we finish mkdir() of missing directories before hash layout assignment). Without this fix, concurrent mkdir() and lookup() will step on each others feet, create a messed up layout on disk, and end up with different in-memory layouts. Once two clients have different in-memory layouts, creation of subdirectory will not arbitrate on the same hashed subvolume and will result in GFID mismatch of the sub-directory.

* build: declare lvm_lv_from_name() if it is missing from lvm2app.hv3.4.0beta4Niels de Vos2013-06-271-0/+6
| | | | | | | | | | | | | | | | | | | | | The bd-xlator can not be built successfully on certain Debian distributions due to a missing declaration of lvm_lv_from_name(). This function is available for linking, but it does not exist in the header file. This change adds a detection for lvm_lv_from_name() in both the library for linking, and the declaration in the header file. If the 1st is missing, the bd-xlator can not be built, and if only the 2nd one is missing, we'll declare lvm_lv_from_name() ourselves. This makes it possible to build the bd-xlator on the affected Debian distributions too.

* glusterd: Disable transport before cleaning up rpc objectKrishnan Parthasarathi2013-06-183-19/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/5000 Problem: rpc_transport object, which is part of rpc_clnt, is destroyed prematurely. This is because, rpc_transport object is ref'd by socket layer and rpc layer. These ref's, until the synctask'izing of operations, were unref'd sequentially in the epoll thread. With more threads at play, the sequential unref guarantee is off. Fix: Shutting down the transport before proceeding with cleaning up of rpc_clnt object would serialize the unref's on the rpc_transport object and thus eliminating the race. Also, we don't store the address of brickinfo in brick's rpc notify function, to avoid the possibility of referring a freed brickinfo. Instead we use a string based id to 'reach' the corresponding brickinfo.

* dht,posix: support for case discoveryAnand Avati2013-06-082-0/+139
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is support for discovering a filename in a given directory which has a case insensitive match of a given name. It is implemented as a virtual extended attribute on the directory where the required filename is specified in the key. E.g: sh# getfattr -e "text" -n user.glusterfs.get_real_filename:FiLe-B /mnt/samba/patchy getfattr: Removing leading '/' from absolute path names # file: mnt/samba/patchy user.glusterfs.get_real_filename:FiLe-B="file-b" In reality, there can be multiple "answers" as the backend filesystem is case sensitive and there can be multiple files which can strcasecamp() successfully. In this case we pick the first matched file from the first responding server. If a matching file does not exist, we return ENOENT (and NOT ENODATA). This way the caller can differentiate between "unsupported" glusterfs API and file not existing. This API is used by Samba VFS to perform efficient discovery of the real filename without doing a full scan at the Samba level.

While this approach works fine, the implementation assumes loc->gfids to be populated at the time of the comparison, but loc may have gfid in loc->inode->gfid instead of loc->gfid which was leading to order mismatches and dead-locks. Fix: Implemented loc_gfid which gives gfid by checking both loc->gfid, loc->inode->gfid. Used this for ordering the blocking entrylks.
