Out of curiosity, how are you mapping the rbd? Have you tried using guestmount? I'm just spitballing, I have no experience with your issue, so probably not much help or useful. On Mon, 5 Feb 2024, 10:05 duluxoz, <duluxoz@gmail.com> wrote:
~~~ Hello, I think that /dev/rbd* devices are flitered "out" or not filter "in" by the fiter option in the devices section of /etc/lvm/lvm.conf. So pvscan (pvs, vgs and lvs) don't look at your device. ~~~
Hi Gilles,
So the lvm filter from the lvm.conf file is set to the default of `filter = [ "a|.*|" ]`, so that's accept every block device, so no luck there :-(
~~~ For Ceph based LVM volumes, you would do this to import: Map every one of the RBDs to the host Include this in /etc/lvm/lvm.conf: types = [ "rbd", 1024 ] pvscan vgscan pvs vgs If you see the VG: vgimportclone -n <make a name for VG> /dev/rbd0 /dev/rbd1 ... --import Now you should be able to vgchange -a y <your VG> and see the LVs ~~~
Hi Alex,
Did the above as you suggested - the rbd devices (3 of them, none of which were originally part of an lvm on the ceph servers - at least, not set up manually by me) still do not show up using pvscan, etc.
So I still can't mount any of them (not without re-creating a fs, anyway, and thus losing the data I'm trying to read/import) - they all return the same error message (see original post).
Anyone got any other ideas? <hopeful tone in voice> :-)
Cheers
