I think it is, I already changed the lvm.conf with: preferred_names=["^/dev/mpath/","^/dev/mapper/mpath","^/dev/[hs]d","^/de v/rbd"] But this is still out commented # filter = [ "a|.*/|" ] -----Original Message----- Cc: ceph-users Subject: RE: [ceph-users] Device /dev/rbd0 excluded by a filter. A quick google shows this: You need to change your /etc/lvm/lvm.conf device name filter to include it. May be that your LVM filter is not allowing rbdX type disks to be used. ---- On Mon, 27 Apr 2020 17:49:53 +0800 Marc Roos <M.Roos@f1-outsourcing.eu> wrote ---- It is a new image. -vvv says "Unrecognised LVM device type 252" Could this related to rbd features not being enabled/disabled? -----Original Message----- Cc: ceph-users Subject: Re: [ceph-users] Device /dev/rbd0 excluded by a filter. This normally means you have some form of partition data on the RBD disk.
