I have not, but if memory serves, a double-dash in an LV name is used as an escape for something different. Look more closely at the "spellings". Though I think you may have confusion between what is a LV and what is a PV. On my (AlmaLinux) server, ceph-volume inventory shows devices like '/dev/nvme01', which is an LVM PV, and the OSD is known as ´/dev/mapper/nvme/osd7' where nvme is the vgname. So no fsids or UUIDs in the names. On 11/10/25 09:22, Francesco Di Nucci wrote:
Hi,
I have provisioned a Ceph cluster with cephadm and I'm having issues with "ceph-volume inventory" on OSD nodes.
It fails with errors like
# ceph-volume inventory --> RuntimeError: /dev/mapper/ceph--009df43a--5864--43ca--9507--59a9c1207e08-osd--block--410f9c5c--c83b--4208--9060--fffd4829ae96 not found.
Even though that device exists under /dev/mapper
I've tried rebooting and node creation with "vgscan --mknodes" but the result is still the same, but nothing. Has anyone encountered the same errors?
Thanks in advance
