[ovirt-users] Re: new host addition, Cannot find master domain

could you run it again, but instead of "--include 253" use number you get when run cat /proc/devices |grep device-mapper| cut -f 1 -d ' ' i.e. INC=`cat /proc/devices |grep device-mapper| cut -f 1 -d ' '` && /usr/bin/lsblk --raw --noheadings --paths --inverse --include $INC --nodeps --output type,name,mountpoint sorry, I was interested in LV tags, i.e. the command should be lvs --readonly --config 'devices {filter=["a|.*|"]}' --options vg_name,vg_tags /dev/sdb yes, it won't be overwritten until you run "vdsm-tool config-lvm-filter" and confirm you want to overwrite it
