Yes it throws the following: This is the recommended LVM filter for this host: filter = [ "a|^/dev/disk/by-id/lvm-pv-uuid-DxNDT5-3NH3-I1YJ-0ajl-ah6W-M7Kf-h5uZKU$|", "a|^/dev/disk/by-id/lvm-pv-uuid-Yepp1J-dsfN-jLh7-xCxm-G7QC-nbaL-6rT2KY$|", "r|.*|" ] This filter allows LVM to access the local devices used by the hypervisor, but not shared storage owned by Vdsm. If you add a new device to the volume group, you will need to edit the filter manually. This is the current LVM filter: filter = [ "a|^/dev/disk/by-id/lvm-pv-uuid-3QbgiW-WaOV-ejW9-rs5R-akfW-sUZb-AXm8Pq$|", "a|^/dev/sda|", "r|.*|" ] To use the recommended filter we need to add multipath blacklist in /etc/multipath/conf.d/vdsm_blacklist.conf: blacklist { wwid "364cd98f06762ec0029afc17a03e0cf6a" } WARNING: The current LVM filter does not match the recommended filter, Vdsm cannot configure the filter automatically. Please edit /etc/lvm/lvm.conf and set the 'filter' option in the 'devices' section to the recommended value. Make sure /etc/multipath/conf.d/vdsm_blacklist.conf is set with the recommended 'blacklist' section. It is recommended to reboot to verify the new configuration. I updated my entry to the following (Blacklist is already configured from before): filter = [ "a|^/dev/disk/by-id/lvm-pv-uuid-DxNDT5-3NH3-I1YJ-0ajl-ah6W-M7Kf-h5uZKU$|","a|^/dev/disk/by-id/lvm-pv-uuid-Yepp1J-dsfN-jLh7-xCxm-G7QC-nbaL-6rT2KY$|","a|^/dev/sda|","r|.*|" ] although then it threw this error [root@ovirt-2 ~]# vdsm-tool config-lvm-filter Analyzing host...

I thought maybe it required a reboot although now it failed to reboot so I am physically going to check on it.
