Hi, when specifying the db device you should use --block.db VG/LV not /dev/VG/LV Zitat von Andrei Mikhailovsky <andrei@arhont.com>:
Hello everyone,
I am running ceph version 15.2.8 on Ubuntu servers. I am using bluestore osds with data on hdd and db and wal on ssd drives. Each ssd has been partitioned such that it holds 5 dbs and 5 wals. The ssd were were prepared a while back probably when I was running ceph 13.x. I have been gradually adding new osd drives as needed. Recently, I've tried to add more osds, which have failed to my surprise. Previously I've had no issues adding the drives. However, it seems that I can no longer do that with version 15.2.x
Here is what I get:

I have tried to find a solution, but wasn't able to resolve the problem? I am sure that I've previously added new volumes using the above command.
lvdisplay shows:
--- Logical volume --- LV Path /dev/ssd3/wal5 LV Name wal5 VG Name ssd3 LV UUID WPQJs9-olAj-ACbU-qnEM-6ytu-aLMv-hAABYy LV Write Access read/write LV Creation host, time arh-ibstorage4-ib, 2020-07-29 23:45:17 +0100 LV Status available # open 0 LV Size 1.00 GiB Current LE 256 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 253:6

How do I resolve the errors and create the new osd?
Cheers
Andrei
