It was up and running. I should mention that the situation came about when I was testing OSD rebuild. So I had a previously autogenerated hybrid OSD, with SSD db, and HDD block dev. I then stopped the OSD, wiped HDD, .... did "ceph osd rm" and ceph auth rm. and then rebuilt with ceph-volume.. with the wrong flags. I belive I used: ceph-volume lvm create --block /dev/xxx --journal /dev/blahblah After that, ceph-volume lvm list claimed it was using the ssd again as db device. but ls -l on /var/lib/ceph/osd/XXXX only showed symlink for block dev. This was on nautilus. ----- Original Message ----- From: "Eugen Block" <eblock@nde.ag> To: "ceph-users" <ceph-users@ceph.io> Sent: Tuesday, April 6, 2021 5:20:40 AM Subject: [ceph-users] Re: which is definitive: /var/lib/ceph symlinks or ceph-volume? Is the OSD up and running? Do you see IO on the dedicated block.db LV when running a 'ceph tell osd.7 bench'? It sounds very strange, I haven't seen that. Zitat von Philip Brown <pbrown@medata.com>:
I am in a situation where I see conflicting information. On the one hand, ls -l /var/lib/ceph/osd/ceph-7 shows a symlink for block device, but no block.db
On the other hand,
ceph-volume lvm list claims that there is a separate db device registered for osd 7
how can I know which one is correct?
(This is currently ceph nautilus)
