Hi Michael, thank you for your response. > So it's not an LSI MegaRAID, but an Intel Controller? It is LSI MegaRAID chip but connected to Intel's I/O Controller Hub (southbridge). On FreeBSD 8.3 gmirror is not configured: # gmirror list gmirror: Command 'list' not available. # gmirror status gmirror: Command 'status' not available. It is somehow enabled through some driver in kernel: # grep ar0 /var/run/dmesg.boot ar0: writing of DDF metadata is NOT supported yet ar0: 952720MB <DDF RAID1> status: READY ar0: disk0 READY (master) using ad4 at ata2-master ar0: disk1 READY (mirror) using ad6 at ata3-master It is probably "soft-RAID", but I prefer to use it though appropriate driver instead of classical software RAID configured through OS. As I said, I'm not that familiar with FreeBSD - how I can check which driver "created" /dev/ar0? Thanks, Bosko
