Yes this option should be exactly what you are looking for. You specify a comma separated list of glob expressions and vdsm will instruct lvm to ignore all devices which are not matched by your list. See: https://www.centos.org/docs/5/html/Cluster_Logical_Volume_Manager/lvm_fil... for more background information on the LVM filters.

I want vdsm to leave alone the VGs called ovirt and kvmvg. lvm_dev_whitelist = [ "r|^/dev/kvmvg|", "r|^/dev/ovirt|" ]

I restarted vdsmd and did not get any error. I also tried to write some bollocks to vdsm.conf, restarted and searched for an error in vdsm.log. surprisingly that also seems to work !?! so the general question actually is: how can i make sure that vdsm.conf options are read correctly. where and when is this checked? what to look for in vdsm.log (or even other log files?) thanks Jojo LINBIT VIE
