Then the 6 disks as JBOD and use it within a RAIDZ2 array. Or, 6 disks in JBOD, add them a 3 ZFS mirror vdev's. Rgds, -- --047d7b6dcb7c0022b304e4dbbb53 Content-Type: text/html; charset=UTF-8

2 smallest disks in RAID1 configuration for booting.

Then the 6 disks as JBOD and use it within a RAIDZ2 array.

Or, 6 disks in JBOD, add them a 3 ZFS mirror vdev's.
