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.
