Hi Fabiand, =20 =20 I have a iSCSI partition on my stateless node. But the problem is I can't format the partition.

Proceed anyway? (y,n) y =20 /dev/sda is apparently in use by the system; will not make a filesystem here! =20 =20 =20 =20 The error message doesn't seem to make sense as the iSCSI partition isn't used by any other machine. =20 =20 =20 Any idea why this isn't working in a stateless node?=20
This doesn't seem to be a stateless problem. Please run findmnt /dev/sda to see if it's mounted. Please also consider to ask your questions on users@ovirt.org or node-devel@ovirt.org - there are more people there to answer. node-devel@ovirt.org is especially good for Node stuff. - fabian
