Today tried:
stop all mds again.
- Forced mds up with ceph mds repaired
- starting mds leads to another crash, with mds not starting.
ceph-post-file: 3775769f-dc90-4ce8-a0b8-6f2bfea14d6c
then I tried to follow the disaster recovery page:
https://docs.ceph.com/docs/nautilus/cephfs/disaster-recovery-experts/#disaster-recovery-experts
I run:
cephfs-journal-tool --rank=pawsey-sync-fs:0 event recover_dentries summary
cephfs-journal-tool --rank=pawsey-sync-fs:0 journal reset
cephfs-table-tool all reset session
Now the mds starts and I can see files with serveral errors in the logs.
This is private though, I posted it there:
ceph-post-file: 6f9f6a57-52ea-4657-878e-0e60e5a069c2
2020-02-10 05:36:36.457 7f8afab48700 0 mds.0.cache.dir(0x609) _fetched

file path" auth v4466 s=2997 n(v0 rc2020-01-16 01:39:10.112907 b2997
1=1+0) (ifi
So the files seems to be there somewhere, but when I mount the
directory, I cannot see them:
There should be a directory in the / but I can see only the files. The
directory seems to be a number:
root@xxxxxxx:/mnt/cephfs# ls -la

How do I recover my files?

Dear all
Running nautilus 14.2.7. The data in the FS are important and cannot
be lost.
Today I increased the PGS of the volume pool from 8k to 16k. The
active mds started reporting slow ops. (the filesystem is not in the
volume pool). After few hours the FS was very slow, I reduced the
backfill to 1 and since the situation was not improving, I restarted
the MDS (no other standby MDSs. it was a single mds).
After that the crash. The mds does not goes back up with this error:

Rebooting did not help
I asked #CEPH OFTC and they suggested to bring up another "fresh"
mds. I did that, and they do not start, going to standby. LOGS:

Can anyone give me some help?
Any command run like journal repairs do not work as they expect the
MDs to be up.
Thanks
