Description Jonathan Earl Brassow 2011-09-16 16:04:46 UTC
Make it possible to take a snapshot of RAID targets (RAID 1/4/5/6).

Comment 1 Jonathan Earl Brassow 2011-09-16 16:12:48 UTC
Release criteria (test requirements):

Ensure that snapshots can be taken of each of the different RAID types (raid1, raid4, raid5, raid5_ls, raid5_la, raid5_rs, raid5_ra, raid6, raid6_zr, raid6_nr, raid6_nc) - that they can be created and remove.  In short, the same snapshot testing should be performed on RAID that is performed on linear or other devices.

Comment 4 Jonathan Earl Brassow 2012-01-27 23:41:01 UTC
All userspace code is in place for snapshots as of the 2.02.89 release.  The kernel has a know issue however.  That is filed under bug 785182 and is blocking this bug.

Comment 8 Jonathan Earl Brassow 2012-04-23 18:19:32 UTC
    Technical note added. If any revisions are required, please edit the "Technical Notes" field
    accordingly. All revisions will be proofread by the Engineering Content Services team.

New Feature to 6.3.  No documentation required.

Bug 732458 is the bug that requires a release note for the RAID features.  Other documentation is found in the LVM manual.

Operational bugs need no documentation because they are being fixed before their initial release.

Comment 13 Corey Marthaler 2012-05-23 21:14:58 UTC
Basic snapshot regression tests have now passed on raid origin volumes with the latest kernel/lvm rpms. Marking verified.
