Hi,
how exactly does ceph report that there’s no CephFS? If your MONs were
down and you recovered them, is at least one MGR also up and running?
Can you share ‚ceph -s‘ and ‚ceph fs status’?

Hi,
I've had a complete monitor failure, which I have recovered fro
My ceph -s output is this:
cluster:
id: bfe08dcf-aabd-4cac-ac4f-9e56af3df11b
health: HEALTH_ERR
1/3 mons down, quorum omicron-m1,omicron-m2
6 scrub errors
Possible data damage: 1 pg inconsistent
Degraded data redundancy: 626702/20558920
There’s no MDS running, can you start it?

I added an MDS, but there was no change in either output (apart from
recognising the existence of an MDS)

This sounds rather risky; will this definitely not lose any of my data?

I don’t understand, what happened to the previous MDS? If there are
cephfs pools there also was an old MDS, right? Can you explain that
please?

Both the MDS maps and the keyrings are lost as a side effect of the monitor
recovery process I mentioned in my initial email, detailed here

.

Alright, I didn't realize that the MDS was affected by this as well.
In that case there's probably no other way than running the 'ceph fs
new ...' command as Yan, Zheng suggested.
Do you have backups of your cephfs contents in case that goes wrong?
I'm not sure if a pool copy would help in any
With that first command, I get this error:
Error EINVAL: pool 'cephfs_metadata' already contains some objects. Use an
empty pool instead.
What can I do?

Nevermind, it works now. Thanks for the help.
