Adding new drives to ceph with ssd DB+WAL

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi - I am trying to add a new hdd to each of my 3 servers, and want to use a spare ssd partition on the servers for the db+wall.   My other OSDs are set up the same way, but I can't seem to keep CEPH from creating the OSDs on the drives before I can actually create the OSD

I am trying to use the commands

ceph orch device zap cube.robeckert.us /dev/sda --force
cephadm ceph-volume lvm create --bluestore --data /dev/sda --block.db /dev/sdc1


ceph orch device zap cube.robeckert.us /dev/sdb--force
cephadm ceph-volume lvm create --bluestore --data /dev/sdb --block.db /dev/sdc2

but by the time the cephadm container is loaded, it says  /dev/sda is in use, and I see  a new OSD created.




I did put in the
#ceph orch apply osd --all-available-devices --unmanaged=true
Command to tell it to not take the OSDs.

Does anyone have any suggestions?  Or is there a way to move the DB+WAL after the OSD is created?

Thanks,
Rob
