If this is true ... Suppose you shutdown a system, remove the ZIL device, and power back on again. What will happen? I'm informed that with current versions of solaris, you simply can't remove a zil device once it's added to a pool. (That's changed in recent versions of opensolaris) ... but in any system where removing the zil isn't allowed, what happens if the zil is removed? I have to assume something which isn't quite sane happens. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
