[ceph-users] Re: Upgrade CEPH 14.x -> 16.X + switch from Filestore to Bluestore = strange behavior

Hi,

I can't say that we upgraded a lot of clusters from N to P, but those that we upgraded didn't show any of these symptoms you describe. But we always did the Filestore to Bluestore conversion before the actual upgrade. In SUSE Enterprise Storage (which we also supported at that time) this was pointed out as a requirement. I just checked the ceph docs, I can't find such a statement (yet).

Hi, Thanks for your answer. Maybe we should have to the switch from FS to BS before but for me, Pacific was the last version of Ceph supporting FS. So we were supposed to have “time”. Olivier
