~~~ 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 Dulux-Oz _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
