And is it possible to add 1 new disk to raidz configuration without backups and recreating zpool from cratch.You can add a disk to a raidz configuration, but then that makes a pool containing 1 raidz + 1 additional disk in a dynamic stripe configuration (which ZFS will warn you about, since you have different fault tolerance then) eg.
You can do that, but then if /tmp/4 fails (in the example), you loose all of the data on that disk. If you were running raid5, you probably care about data-loss and cost -- and this configuration only cares about cost.
