So with upgrading one should
Hi Frank,
we converted the OSDs directly on the upgrade.
1. installing new ceph versions
2. restart all OSD daemons
3. wait some time (took around 5-20 minutes)
4. all OSDs were online again.
So I would expect, that the OSDs are all upgraded correctly.
I also checked when the trimming happens,
I checked the cluster for other snaptrim operations and they happen all
over the place, so for me it looks like they just happend to be done when
the issue occured, but were not the driving factor.
