* glusterd: Improve debugging experience for glusterd locksKrishnan Parthasarathi2014-09-031-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | Today, when glusterd's internal locking mechanism fails with invalid type or when another competing lock is being held, the log message doesn't provide enough information directly as to which command saw this (first). Following is a snippet of how a failure would look in the log file. This would greatly assist in debugging.

* glusterd: Prevent rebalance starting with old clientsKaushal M2014-09-035-38/+81
| | | | | | | | | | | | | | | | | Glusterd will prevent rebalance from starting when clients older than glusterfs-v3.6.0 are connected to a volume. This is needed as running rebalance with old clients connected could lead to data loss in some cases. The DHT xlator on newer clients (>= 3.6.0) has been fixed to prevent the data loss issues.

* cluster/dht: remove specifying cached-subvol as part of name inRaghavendra G2014-09-021-12/+1
| | | | | | | | | | | | | | | | | | | | | | unlink. commit 667b2496c3f29e24ed359a05b0f44df0d1894969 introduced a functionality where we can specify the subvol where file is stored. As part of same commit, dht_unlink was also changed to accept cached-subvol as part of name. While it makes sense to specify subvol while creating file, there is no necessity for specifying the subvol during unlink, since the default unlink logic works fine with this functionality too. Also, this code in unlink doesn't work well when files get migrated by rebalance process. Hence removing it.

* cluster/dht: Modified test case to note rename failures as errorsShyam2014-09-021-13/+7
| | | | | | | | | | | | | | | | | | | | | | | | | The bug referenced in this change, had an race condition that is now fixed by the following commits that are posted for review. http://review.gluster.org/#/c/8563/ http://review.gluster.org/#/c/8570/ These changes would now make the winning client not fail a rename, in case it failed to rename the linkto file. Hence when one client wins the link race, and the other still deletes the linkto file, the rename failure by the winning client is not a critical failure, hence it resolves the issue posted in the bug. As a result modifying the test case to treat the rename failures as errors, to catch any future issues.

* cluster/dht: Rename should not fail post hardlink creationShyam2014-09-022-41/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | In the rename path, we wind the creation of newname hardlink and linkto file in dst hashed a the same time. If the linkto creation fails, but the link creation succeeds, we enter the failure code and cleanup the created newname hardlink. In the interim if another client looks up newname and finds it as a hardlink from FUSE, it could send an unlink for oldname instead of a rename. This combined with the above cleanup code could end up losing all the files copies, and thereby losing data. This fix separates these steps into 2 parts, creating the linkto first and then the link file, so that post link file creation no failures would cleanup the newname file. If linkto fails then link is not attempted, thereby not polluting the name space with newname.

* cluster/dht: Treat linkto file rename failure as non-critial errorShyam2014-09-021-8/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is a critical failure iff we fail to rename the cached file if the rename of the linkto failed, it is not a critical failure, and we do not want to lose the created hard link for the new name as that could have been read by other clients. NOTE: If another client is attempting the same oldname -> newname rename, and finds both file names as existing, and are hard links to each other, then FUSE would send in an unlink for oldname. In this time duration if we treat the linkto as a critical error and unlink the newname we created, we would have effectively lost the file to rename operations. Repercussions of treating this as a non-critical error is that we could leave behind a stale linkto file and/or not create the new linkto file, the second case would be rectified by a subsequent lookup, the first case by a rebalance, like for all stale linkto files Change-Id: Ia53ad8b43c3cf8f48ef5b43fd1fec4274e807556 BUG: 1130888 Signed-off-by: Shyam <srangana@redhat.com> Reviewed-on: http://review.gluster.org/8563 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

* storage/posix: Prefer gfid links for inode-handlePranith Kumar K2014-09-023-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: File path could change by other entry operations in-flight so if renames are in progress at the time of other operations like open, it may lead to failures. We observed that this issue can also happen while renames and readdirps/lookups are in progress because dentry-table is going stale sometimes. Fix: Prefer gfid-handles over paths for files. For directory handles prefering gfid-handles hits performance issues because it needs to resolve paths traversing up the symlinks. Tests which test if files are opened should check on gfid path after this change. So changed couple of tests to reflect the same. Note: This patch doesn't fix the issue for directories. I think a complete fix is to come up with an entry operation serialization xlator. Until then lets live with this.

This was written after countless hrs of effort to get a sane `pidof` working on either of the environments. `pidof` comes at the wake of lack of proper procfs support and also incompatible way of handling process names since glusterd/glusterfs are symbolic links to 'glusterfsd' - tests/utils/* directory should be part of 'PATH' to avoid abspath calculation using $(dirname) - cleanup() - rpcinfo command prints error on FreeBSD/OSX fix it Change-Id: I35f86273624cb279da1c8fae056ca27669e251d8 BUG: 1131713 Signed-off-by: Harshavardhana <harsha@harshavardhana.net> Reviewed-on: http://review.gluster.org/8499 Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com>

* Fix glustershd detection on volume restartEmmanuel Dreyfus2014-08-252-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | On NetBSD and FreeBSD, doing a 'gluster volume start $volume force' causes NFS server, quotad, snapd and glustershd to be undetected by glusterd once the volume has restarted. 'gluster volume status' shows the three processes as 'N' in the online column, while they have been launched successfully. This happens because glusterd attempts to connect to its child processes just between the child does a unlink() on the socket in __socket_server_bind() and the time it calls bind() and listen(). Different scheduling policy may explain why the problem does not happen on Linux, but it may pop up some day since we make no guaranteed assumptions here. This patchet works this around by introducing a boolean transport.socket.ignore-enoent option, set by nfs and glustershd, which prevents ENOENT to be fatal and cause glusterd to retry and suceed later. Behavior of other clients is unaffected.

Fix: - Remove resolution error handling in FUSE_FOP as it was only added to handle fd migration failures. - check in fuse_resolve_done for fd resolution failures and fail the fop right away. - loc resolution failures are already handled in the corresponding fops. - Return errno from state->resolve.op_errno in resume functions. - Send error to fuse on frame allocation failures. - Removed unused variable state->resolved - Removed unused macro FUSE_FOP_COOKIE Change-Id: I479d6e1ff2ca626ad8c8fcb6f293022149474992 BUG: 1126048 Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: http://review.gluster.org/8402 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
