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
Nir
See above:
[root@ovirt01 etc]# lsblk

Are you sure this is the correct host that the multipath error came from?
There are no multipath devices in this host and no ovirt storage domains lvs.
Nir
Yes this is the host. I'm sure.
I've not yet configured ovirt storage domains (only installed ovirt on host and
self hosted engine VM)
