Run RAID on the remote iSCSI system and don't try to do RAID between two networked iSCSI volumes, it will hurt performance even more. > Why md0 is not activated when I reboot this server?

You must manually start the RAID volume after the iSCSI sessions are established. The exception would be if you were using a hardware iSCSI HBA in which case the devices wouldn't show up as iSCSI volumes they would show up as SCSI volumes and be available immediately upon booting, as the HBA would handle session management. nate
