Hello, solaris Internals wiki contains many interesting things about zfs. But i have no glue about the reasons for this entry:
In Section "ZFS Storage Pools Recommendations - Storage Pools" you can read: [i]For all production environments, set up a redundant ZFS storage pool, such as a raidz, raidz2, or a mirrored configuration, regardless of the RAID level implemented on the underlying storage device.[/i] (see <http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide#Storage_Pools>) In our environment we use EMC based storage subsystems which are protected by RAID1 (mirrored disks). What's the reason for building an upper level zfs mirror on these already mirrored disks? Or do I misinterpret solaris internals wiki?
