Red Hat Bugzilla – Bug 1274101
need a way to pause/stop tiering to take snapshot
Last modified: 2015-11-17 01:01:01 EST
+++ 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.

Migration is restarted after snap completes. For testing an internal switch is added.
