+++ This bug was initially created as a clone of Bug #1267950 +++ We need a way to pause tiering to take snapshot. A file cannot be in the middle of promotion/demotion when a snapshot is taken. If a file is in the middle of migration, abort the migration and rollback any in-progress work. Implement a CLI for this and to resume migration. --- Additional comment from Vijay Bellur on 2015-10-13 21:24:12 EDT --- REVIEW: http://review.gluster.org/12304 (cluster/tier: WIP add pause tier feature (required for snapshots)) posted (#3) for review on master by Dan Lambright (dlambrig@redhat.com) --- Additional comment from Vijay Bellur on 2015-10-14 23:11:23 EDT --- REVIEW: http://review.gluster.org/12304 (cluster/tier: add pause tier for snapshots) posted (#4) for review on master by Dan Lambright (dlambrig@redhat.com) --- Additional comment from Vijay Bellur on 2015-10-16 11:36:14 EDT --- REVIEW: http://review.gluster.org/12304 (cluster/tier: add pause tier for snapshots) posted (#5) for review on master by Dan Lambright (dlambrig@redhat.com) --- Additional comment from Vijay Bellur on 2015-10-19 14:24:17 EDT --- REVIEW: http://review.gluster.org/12304 (cluster/tier: add pause tier for snapshots) posted (#6) for review on master by Dan Lambright (dlambrig@redhat.com) --- Additional comment from Vijay Bellur on 2015-10-21 10:27:52 EDT --- REVIEW: http://review.gluster.org/12304 (cluster/tier: add pause tier for snapshots) posted (#7) for review on master by Dan Lambright (dlambrig@redhat.com) --- Additional comment from Vijay Bellur on 2015-10-21 12:20:15 EDT --- REVIEW: http://review.gluster.org/12304 (cluster/tier: add pause tier for snapshots) posted (#8) for review on master by Dan Lambright (dlambrig@redhat.com) --- Additional comment from Vijay Bellur on 2015-10-21 18:44:40 EDT --- COMMIT: http://review.gluster.org/12304 committed in master by Dan Lambright (dlambrig@redhat.com) ------ commit 36974c36fa4231df3f0e9428a9da6d1aa33348ab Author: Dan Lambright <dlambrig@redhat.com> Date: Mon Oct 5 19:52:02 2015 +0000 cluster/tier: add pause tier for snapshots Snaps of tiered volumes cannot handle files undergoing migration. We implement a helper mechanism to "pause" migration. Any files undergoing migration are aborted. Clean up is done to remove sticky bits and data at the destination. Migration is restarted after snap completes. For testing an internal switch is added.
