We recently had a long discussion in this list, about resilver times versus raid types. In the end, the conclusion was: resilver code is very inefficient for raidzN. Someday it may be better optimized, but until that day comes, you really need to break your giant raidzN into smaller vdev's. 3 vdev's of 7 disk raidz is preferable over a 21 disk raidz3. If you want this resilver to complete, you should do anything you can to (a) stop taking snapshots (b) don't scrub (c) stop all IO possible. And be patient. Most people in your situation find it faster to "zfs send" to some other storage, and then destroy & recreate the pool. I know it stinks. But that's what you're facing. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
