Thank you. If you don't know the answer to this off the top of your head, I'll go attempt the internet, but thought you might just know the answer in 2 seconds ... Assuming the disk's write cache is disabled because of the slice (as documented in the Best Practices Guide) how do you enable it? I would only be using ZFS on the drive. The existence of a slice is purely to avoid future mirror problems and the like. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
