FreeBSD morninglightmountain.hacktor.net 8.0-CURRENT FreeBSD 8.0-CURRENT #2: Mon Apr 27 22:37:12 UTC 2009 root@morninglightmountain.hacktor.net:/usr/obj/usr/src/sys/MORNINGLIGHTMOUNTAIN sparc64
I did a "dd if=/dev/zero of=/dev/ad1 bs=1m count=1", but that doesn't change anything.
writing a new label does not help either :
morninglightmountain# sunlabel -w ad1 auto
morninglightmountain# gpart show ad1
=> 0 48338640 ad1 VTOC8 (149G)
0 48338640 - free - (23G)
