Hi,
We would like to share our experience upgrading one of our clusters from
Nautilus (14.2.22-1bionic) to Pacific (16.2.10-1bionic) a few weeks ago.
To start with, we had to convert our monitors databases to rockdb in
order to continue with the upgrade. Also, we had to migrate all our OSDs
to bluestore, otherwise they wouldn't come up after upgrading. That
being said and done, once we finalized the upgrade, we bumped
into big performance issues with snaptrims. The I/O of the cluster was
nearly stalled when our regular snaptrim tasks run. IcePic
pointed us to try compacting the OSDs. This solved it for us. It seems
this was an already known issue and a fix is already integrated
in the upgrade process, however it didn't work for us.

We just wanted to share in case other people bump into same issues.
Greetings,
