For the sake of curiosity, is it safe to have components of two different ZFS pools on the same drive, with and without HDD write cache turned on?
How will ZFS itself behave, would it turn on the disk cache if the two imported pools co-own the drive? An example is a multi-disk system like mine which had UFS-mirrored root and a ZFS-raidz2 for data, then was upgraded to a ZFS-mirrored root with another ZFS pool for data (partially since grub doesn't do ZFS roots on zfs-raidz*). PS: for a system with 1 or 2 drives, is there any preference to either layout: 1) sliced with 2 zpools (root and data) 2) sliced with one zpool for all 3) whole-disk with 1 zpool for all (is that supported by GRUB for boot disks at all?) -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
