* glusterd/snapshot: Fix for snapshot restore failureRajesh Joseph2014-06-131-9/+9
| | | | | | | | | | | | | | | | | | | Problem: If restore fails due to quorum failure then the subsequent restore fails. Cause: Volume store is backed up during prevalidate failure and it is reverted or cleaned based on failure or success of the commit phase. In case of quorum failure we were not reverting the backup. Fix: Take backup when all the validation is done including quorum check.

* glusterd/snapshot : Provide enable/disable option for snapshot auto-delete ↵Sachin Pandit2014-06-134-20/+226
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | feature. This patch provides an interface to enable or disable the auto-delete feature. Syntax : gluster snapshot config auto-delete <enable/disable> DETAILS : 1) When auto-delete feature is disabled, If the the soft-limit is reached then user is given a warning about exceeding soft-limit along with successful snapshot creation message (oldest snapshot is not deleted). And upon reaching hard-limit further snapshot creation is not allowed. Example : ------------------------------------------------------------------ |Case - 1: Upon reaching soft-limit | |Snapshot create : snap successfully created. |Warning : soft-limit of volume (vol) is reached. Snapshot creation |is not possible once hard-limit is reached. | |----------------------------------------------------- |Case - 2: Upon reaching hard-limit | |Snapshot create : snap creation failed. |Error : hard-limit of volume (vol) is reached, Hence it is not |possible to take further snapshots. Please delete few snapshots |of the volume (vol) before taking another snapshot. ------------------------------------------------------------------ 2) When auto-delete feature is enabled, then as soon as the soft-limit is reached the oldest snapshot is deleted for every successful snapshot creation (same as existing method), With this it is made sure that number of snapshot created is not more than snap-max-hard-limit.

| | | | | | | | | | | | | | | | | | | | | | | | Now this is how autodelete behaves: 1) Upon creation when the max-soft-limit exceeds, the oldest snapshot is deleted. i.e if hard limit is 100 and by default soft limit is 90. Whenever snap count reaches 90, every new create results in the deletion of the oldest snapshot. 2) If the snap limit (hard) is reconfigured and brought down the current snap count, then no snapshot is deleted and the next snapshot create fails as the current snapcount is more than the hard limit. 3) When soft limit is brought down: say max limit is 100 and by default soft limit is 90 and current snap count is 90. Now, soft limit is changed to 70 (70%). In this case the snapshot count remains 90 itself (i.e extra 20 snapshots more than the soft limit are not deleted) and for every new create the oldest snapshot is deleted.

* glusterd: Better op-version values and rangesKaushal M2014-06-098-42/+42
| | | | | | | | | | | | | | | | | | | | | | | | | Till now, the op-version was an incrementing integer that was incremented by 1 for every Y release (when using the X.Y.Z release numbering). This is not flexible enough to handle backports of features into Z releases. Going forward, from the upcoming 3.6.0 release, the op-versions will be multi-digit integer values composed of the version numbers, instead of a simple incrementing integer. An X.Y.Z release will have XYZ as its op-version. Y and Z will always be 2 digits wide and will be padded with 0 if required. This way of bumping op-versions allows for gaps in between the subsequent Y releases. These gaps will allow backporting features from new Y releases into old Z releases.

* glusterd: Preserve backward compatibility during sync and storeKaushal M2014-06-052-168/+386
| | | | | | | | | | | | | | | | | | | | | | | | | | The glusterd volinfo struct gained several new members to support the volume snapshot feature. These members are also being exported/imported during volume sync and being stored/restored. This export/import and save/restore explicitly required these members to be present, and would fail if they were not. This lead to the failure of backward compatibility, preventing new peers from correctly interacting with older peers (especially during a rolling upgrade). This patch contains changes needed to preserve the backward compatibility in the places specified. The snapshot members of the volinfo will now be exported/imported and stored only when the cluster op-version is >= 4, ie. all peers in the cluster support snapshot. No change is required for the restore code as, the new members will be left at the default zero values if corresponding entries are absent in the stored volinfo.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Currently rpc_connect calls the notification function on failure in the same thread, glusterd notification holds the big_lock and hence big_lock is released before rpc_connect In snapshot creation, releasing the big-lock before completeing operation can cause problem like deadlock or memory corruption. Bricks are started as part of snapshot created operation. brick_start releases the big_lock when doing brick_connect and this might cause glusterd crash. There is a similar issue in bug# 1088355. Solution is let the event handler handle the failure than doing it in the rpc_connect.

Hence during snapshot create and in-turn snapshot restore the barrier value is set to enable. Because of this further I/O on the mount point fails.

On a non-root setup, Gluster CLI would run as an unprivileged user, failing to execute the command. As a workaround (for testing), setuid(2) Gluster CLI executable or use the glusterd option to accept commands by unprivileged CLI process. The nature of cli commands are "system::" commands (for key management) and remote volume info fetching. Remote volume info fetching has been modified to use --remote-host gluster cli option rather than ssh and remote cli execution.

* glusterd: On gaining quorum spawn_daemons in new threadKaushal M2014-05-124-28/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | During startup, if a glusterd has peers, it waits till quorum is obtained to spawn bricks and other services. If peers are not present, the daemons are started during glusterd' startup itself. The spawning of daemons as a quorum action was done without using a seperate thread, unlike the spawn on startup. Since, quotad was launched using the blocking runner_run api, this leads to the thread being blocked. The calling thread is almost always the epoll thread and this leads to a deadlock. The runner_run call blocks the epoll thread waiting for quotad to start, as a result glusterd cannot serve any requests. But the startup of quotad is blocked as it cannot fetch the volfile from glusterd. The fix for this is to launch the spawn daemons task in a seperate thread. This will free up the epoll thread and prevents the above deadlock from happening.
