Hi Harald,
We have 2 clusters upgraded to Pacific, they're working well although we
had an issue triggered by Proxmox 7 cluster instability and Ceph didn't
recover very well. (see my previous posts)
You won't hit data-lossing bug if you don't trigger it after upgrading,
that is the current understanding here and on Ceph user mailing list.
Anyway I recommend not to upgrade to Pacific yet, we stopped upgrading
clusters we manage until Pacific is more mature.
Cheers

Hi,
the ceph release packages site has a big red warning not to upgrade
from earlier versions to Pacific.
So when I haven't updated to Pacific yet, should I wait or is it safe
to upgrade for what ever reason?

DO NOT UPGRADE TO CEPH PACIFIC FROM AN OLDER VERSION.
A recently-discovered bug (https://tracker.ceph.com/issues/53062) can
cause data corruption. This bug occurs during OMAP format conversion
for clusters that are updated to Pacific. New clusters are not
affected by this bug.
The trigger for this bug is BlueStore’s repair/quick-fix
functionality. This bug can be triggered in two known ways:
manually via the ceph-bluestore-tool, or
automatically, by OSD if bluestore_fsck_quick_fix_on_mount is set to
true.
The fix for this bug is expected to be available in Ceph v16.2.7.
DO NOT set bluestore_quick_fix_on_mount to true. If it is currently
set to true in your configuration, immediately set it to false.
DO NOT run ceph-bluestore-tool’s repair/quick-fix commands.

thanks
Harald
