Hi,
I just upgraded from 17.2.6 to 18.2.1 and have some issues with mds.
mds started crashing with
2023-12-27T13:21:30.491+0100 7f717b5886c0 1 mds.f9sn015 Updating MDS

and I could not bring it back again. As a workaround I was able to start
mds 17.2.6 and it somehow recovered.
Then I started 18 mds again, which soon after startup finds this corruption:
[
{
"damage_type": "dentry",
"id": 4247331390,
"ino": 1,
"frag": "*",
"dname": "lost+found",
"snap_id": "head",
"path": "/lost+found"
}
]
There are few corrupted files in some other directories ( leftovers from
several releases before I never managed to fix), and if I start mds
scrub there, mds crashes again, maybe because of corrupted lost+found.
If I try to remove lost+found, mds crashes again.
Do you have any hint how to recover from this?
Best regards,
Andrej
