Hi,
After investigating the logs I believe that there were few issues that
might have caused this unstable behavior.
1) Looks like the DB still contained some leftovers from the already fixed
bug which was causing duplicate entries. Even after the date of engine
upgrade I still saw some "Duplicate key" errors. I suggest cleaning the DB
(if that is possible).
2) Also saw a few other known (and already reported) issues that also might
have caused the problem. The issues are going to be fixed in the coming
4.4.9 version, resulting in more stability.
I asked our QE team to inform me if they encounter this 'disks stuck in
FINALIZING' issue, so I'll be able to try and investigate it locally.
But again, this issue might be caused by either some DB leftovers or issues
that we are already WIP fixing them.
If you opened a bug, please send the link to it here.
Thank you in advance.
Pavel
