I read this earlier, that it's recommended to use a whole disk instead of a partition with zfs, the thing that's holding me back however is the mixture of different sized disks I have. I suppose if I had a 300gb per disk raid-z going on 3 300 disk and one 320gb disk, but only have a partition of 300gb on it (still with me), i could later expand that partition with fdisk and the entire raid-z would then expand to 320gb per disk (assuming the other disks magically gain 20gb, so this is a bad example in that sense :) ) Also what about full disk vs full partition, e.g. make 1 partition to span the entire disk vs using the entire disk. Is there any significant performance penalty? (So not having a disk split into 2 partitions, but 1 disk, 1 partition) I read that with a full raw disk zfs will be beter to utilize the disks write cache, but I don't see how. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
