Hi:
With yet another gluster disk failure / gluster collapse, it appears I
lost the "main" backing image for one of my vm servers. I have snapshots
still in tact (or at least, appear to be), but the main image is gone.
Is there a possibility of recovering data from gluster? When you say lost -
are the files deleted from all bricks?
The main server process stores a backup at regular intervals in its
disk,
and that would have been changed data, so it would be in the snapshot
rather than the base image. Is there any way to recover this one .tar.gz
file from the snapshot with the missing main image? This is a backup of
dynamic data, and without it, I will have lost several customers data, some
of which cannot be recreated/regenerated.
Are these qemu snapshot or gluster volume snapshot?
it also appears that my backup (gluster geo-replication) did not work
(had
crashed a while ago, and has a very old backup of this image).
