Hi all
I've just setup a new system with 11 x 7-drive RAIDz2 VDEVS. Running iozone to
benchmark and test the system, it seems it's running horribly slow. iostat -xd
shows one (or two) drives slowing down the bunch, and zfs-stats.sh (by
Alasdair, grab it from http://karlsbakk.net/zfs-stats.sh )
Hi all
I have installed a new server with 77 2TB drives in 11 7-drive RAIDz2 VDEVs,
all on WD Black drives. Now, it seems two of these drives were bad, one of them
had a bunch of errors, the other was very slow. After zfs offlining these and
then zfs replacing them with online spares, resilver

until your spares are no longer in use.

Thanks for the clarification. Wouldn't

Thanks for the clarification. Wouldn't it be nice if ZFS could fail
over
to a spare and then allow the replacement as the new spare, as with
what
is done with most commercial hardware RAIDs?
If you use zpool detach to remove the disk that went bad, the spare
is promoted to a proper
