If the disk has VTOC label, there is no "c1t0d0".. ZFS will see that you're "kinda" referring to the whole disk and change it into EFI. With the second version, you're using a slice (that just happen to cover all of the disk) and it won't change to EFI and won't mess around with the write cache for additional performance. /Tomas -- Tomas Ögren, [EMAIL PROTECTED], http://www.acc.umu.se/~stric/ |- Student at Computing Science, University of Umeå `- Sysadmin at {cs,acc}.umu.se _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
