Hi, Igor!
Service is UP.
This prevents ceph-bluestore-tool from starting, you should shutdown it
first.
I did not make separate devices.
blocks.db and blocks.wal are created only if they are on separate devices?
in general - yes. They make sense when using separate devices only...

Hi Andrey,
this log output rather looks like some other process is using
/var/lib/ceph/osd/ceph-8
Have you stopped OSD.8 daemon?
And are you sure you deployed standalone DB/WAL devices for this OSD?
Thanks,
Igor

Hello,
Some time ago I deployed a ceph cluster.
It works great.
Today I collect some statistics and found that the BlueFs utility is not working.

inferring bluefs devices from bluestore path

As far as I understand, blocks.db and blocks.wal are missing. I don’t know how it turned out.

Did as standard:
....
ceph-deploy osd create test-host1:/dev/sde
ceph-deploy osd create test-host2:/dev/sde
....
What now to do and whether it is necessary to repair it at all?
Assembled on luminous, yesterday updated to Nautilus.
