After ovirt installation on host console I see this error every 5 minutes:
[ 1823.837020] device-mapper: table: 253:4: multipath: error getting device [ 1823.837228] device-mapper: ioctl: error adding target to table This may be caused by the fact that vdsm does not cleanup properly after deactivating storage domains. We have an open bugs on this.
You may have an active lv using non-existent multipath device.
Can you share with us the output of:
lsblk multipath -ll dmsetup table cat /etc/multipath.conf pvscan --cache > /dev/null && lvs
