Hi,
am really new to gluster and have couple question that I
hope will be really easy to answer. Just couldn't find
anything on that myself.
I did set up replica 3 gluster over 3 nodes with 2TB SSD in
each node.
To have snapshot functionality I have created thin pool of
the size of VG (1.82TB) and then 1.75TB thin LVM inside on
each of the bricks.
It worked just fine until I scheduled creating hourly and
daily snapshots on that gluster volume. In less than 2 days my
thin volume got full and crashed.
Not refused creating new snapshots, but just died as LVM
couldn't perform any operations there anymore.
So my first question is how to prevent this from happening.
I could create smaller thin LVM, but I still have no control
how much space I would need for snapshots. I was hoping to see
some warnings and errors while creeating snapshots, but not
failed LVM/Gluster.
The second question is related but not that important. Is
there a way to schedule snapshot removal in cron? gluster
snapshot delete requires interactive confirmation and I don't
see any flag to auto-confirm snapshot removal.
