I mistyped the storage allocation for an additional virtio drive for one of our vm guests and now I cannot get rid of the thing. I have discovered that this is probably, indeed almost certainly, related to udev but the few work arounds I have found all seem to fail for me. Does anyone here know how to remove these things? When I try this: # for i in {1..200}; do udevadm control --stop-exec-queue ; lvremove -f /dev/vg_vhost01/lv_vm_inet05.harte-lyne.ca_01; udevadm control --start-exec-queue; done I get hundreds of these: Logical volume vg_vhost01/lv_vm_inet05.harte-lyne.ca_01 is used by another device. # lsof /dev/vg_vhost01/lv_vm_inet05.harte-lyne.ca_01 # I recall that I ran into this before and I have a sinking feeling that the 'fix' was to reinstall the then new virtual host OS. I have (re-)opened a bug report: https://bugzilla.redhat.com/show_bug.cgi?id=855409 But if anyone has a recipe to deal with this I would be grateful if you would share it. -- *** E-Mail is NOT a SECURE channel *** James B.
