There's a problem with mkraid creating a raid device where the individual devices are each over 2TB: [root@rad7 3dm2]# mkraid --really-force /dev/md0 DESTROYING the contents of /dev/md0 in 5 seconds, Ctrl-C if unsure! handling MD device /dev/md0 analyzing super-block couldn't get device size for /dev/sdb -- File too large mkraid: aborted. (In addition to the above messages, see the syslog and /proc/mdstat as well for potential clues.) The kernel (2.6.8-1) is able to read the device, although with a warning: Aug 26 16:38:59 localhost kernel: sdb : very big device. try to use READ CAPACITY(16). Aug 26 16:38:59 localhost kernel: SCSI device sdb: 4687368192 512-byte hdwr sectors (2399933 MB) I assume mkraid needs to do something like use READ CAPACITY(16). There's a similar problem with mdadm and I've discussed this with Neil Brown who plans to fix it. I don't know if mkraid is being actively maintained, but if someone does come up with a patch soon, then I would be willing to try it.
