I have a ceph node that has an os filesystem going into read only for what ever
reason[1].
1. How long will ceph continue to run before it starts complaining about this?
Looks like it is fine for a few hours, ceph osd tree and ceph -s, seem not to
notice anything.
2. This is still nautilus with majority of ceph-disk and maybe some ceph-volume
disks
What would be a good procedure to try and recover data from this drive to use
on a new os disk?
