Re: [Users] How to pxeboot ovrit node into memory automatically?

Hi Fabiand, =20 =20 I have a iSCSI partition on my stateless node. But the problem is I can't format the partition. The same partition can be formatted and mounted on a regular machine without problems.=20 =20 =20 [root@localhost ~]# mkfs.ext3 /dev/sda mke2fs 1.42.7 (21-Jan-2013) /dev/sda is entire device, not just one 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
