* cluster/afr: Fail readv on data-split-brainPranith Kumar K2013-01-183-0/+23
| | | | | | | | | | | | | | | | | | Problem: Afr prevents opens on a file in split-brian but the fd that is already open still has the capability to perform both reads and writes to the file. Fix: Fail readvs on a file with EIO.

* glusterd: replace obsolete /usr/local reference for remote ssh/gsyncdKaleb S. KEITHLEY2013-01-181-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | See https://bugzilla.redhat.com/show_bug.cgi?id=895656 https://bugzilla.redhat.com/show_bug.cgi?id=764679 (GLUSTER-2947) https://bugzilla.redhat.com/show_bug.cgi?id=764623 (GLUSTER-2891) The comments in the bzs are a bit obtuse and/or vague. As near as I can make out we had, for a while, a "convenience symlink" to or from /usr/local/libexec/gsyncd, which no longer exists. And, lacking any comments in the code, I gather this is some sort of fallback or failsafe logic: if the first, normal attempt to invoke gsyncd fails then an attempt is made to ssh to the box and invoke it. In any event, there's nothing in /usr/local/... so it's unquestionably wrong to try to invoke anything there. BUG: 895656 Change-Id: I3b7ac7a049b91ce101b930599294830147cc60ad Signed-off-by: Kaleb S.

* afr: conditionally prioritize EIO errors over ENOENTBrian Foster2013-01-183-7/+12
| | | | | | | | | | | | | | | | | | | | | | | | The most important errno logic historically only prioritized ESTALE over ENOENT. Commit c8c0942d added EIO prioritization over ENOENT to ensure that split-brain was reported when it occurs in conjunction with bricks missing the file entry. The unintended side effect of this change is that (non split-brain) EIO errors reported from the bricks themselves are now reported to the client when the expectation is that afr should squash said errors in favor of marking the file inconsistent. The high-level problem is that EIO is overloaded with different meanings from different contexts. This commit adds an eio parameter to the errno priority logic to conditionally flag when EIO is of higher priority and should be propagated to the client.

* afr: replace afr_more_important_error with afr_most_important_errorBrian Foster2013-01-173-26/+18
| | | | | | | | | | | | | | | | | | | | | afr_more_important_error() is written to return whether a new errno should override an existing errno for high-level operations that could span multiple sub-operations. It specifically prioritizes ESTALE over EIO over ENOENT, and otherwise defaults to the latest error passed having priority. This change preserves current behavior, but rewrites the logic to return the higher priority error of the existing and new errno. The purpose of the change is to make the logic a bit more clear and set the stage for future changes to make the logic flexible based on context.

| | | | | | | | | | | | | | | | | | | | | | Problem: When fop fails post-op is always performed over the network irrespective of whether pre-op is piggybacked or not. Decrementing Pre-op-done count even for the piggybacked ones is wrong.

| | | | | | | | | | | | | | | | | | | | | - enable-pump option in the pump xlator is set during a replace-brick session. This was persisted in the volinfo->dict for volume file generation. It has two 'harmful' side-effects, a) It would lead to volinfo cksum divergence among peers in cluster (for the same version no.) during a replace-brick session. b) "enable-pump" key would appear in "gluster volume info VOLNAME". This key is used internally in volume file generation code to optionally load the pump xlator in the source brick. It is _not_ an volume option.

But it winds up deleting all the options irrespective of whether the pattern match was successful or not. The same is true with _copy_auth_opt(). FIX: Changed _delete_auth_opt() to delete the key ONLY if it matches either of the two patterns (auth.addr.*.allow and auth.addr.*.reject). Similarly, changed _copy_auth_opt() along the same lines.

* glusterd: log appropriate message when locking failsKrutika Dhananjay2012-12-1111-197/+379
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PROBLEM: When a transaction is already in progress, and the user tries to execute another glusterd operation, the second operation fails as glusterd fails to acquire lock. But to the user, a message like "Operation failed" does not give ample information about why the operation failed. FIX: Made glusterd_op_txn_begin use and initialise error string, which is needed to capture failure in the "lock" phase. Also made gd_sync_task_begin set error string appropriately when locking fails. In the process, I had to introduce error string in some glusterd_handle_* functions. And because I introduced error string in these handlers, I decided to also set them in places where these handlers could possibly fail. HOW I TESTED IT: For want of a better idea, I "commented out" the call to "glusterd_unlock", recompiled glusterd and ran two glusterd volume operations, one after the other. The second operation fails with the message "Another transaction is in progress. Please try again after sometime." as expected. The tests were performed on two volume ops : one of them synctask'ized (volume start) and the other NOT (volume create).

| | | | | | | | | | | | | | | | | | | | | | Problem: When create/mknod fails on some of the nodes, appropriate pending data/metadata changelogs are not assigned. This was not considered to be an issue because entry self-heal would do the assigning of appropriate changelog after creating new entries. But using the combination of rebalance and remove brick we can construct a case where a file with same name and gfid can be created in a dir with different data and link-to xattr without any changelog. Fix: When a create/mknod failure is observed mark the appropriate changelog on the new file created.

* afr: use data trylock mode in read/write self-heal trigger pathsBrian Foster2012-12-041-1/+8
| | | | | | | | | | | | | | | | | | | | | | Self-heal data lock contention between clients and glustershd instances can lead to long wait and user response times if the client ends up pending its lock on glustershd self-heal of a large file. We have reports of guest vm instances going completely unresponsive during self-heal of virtual disk images. Optimize the read/write self-heal trigger codepath (i.e., afr_open_fd_fix()) to trylock for self-heal and skip the self-heal otherwise to minimize the likelihood of a running/active guest of competing with glustershd on arrival of a brick. Note that lock contention is still possible from the client (e.g., via lookup).

An id is generated for each task when it is started and displayed to the user in cli output. The status of running tasks is also included in the output of "volume status" along with its id, so that a user can easily track the progress of an async task. Also, * added tests for this feature into the regression test suite. * added a python script for creating files, 'create-files.py', courtesy Vijaykumar Koppad (vkoppad@redhat.com) into the test suite.
