I'm not sure if you're subscribed to -stable or not, so here's the thread: http://lists.freebsd.org/pipermail/freebsd-stable/2008-January/039791.html The problem folks are having are with using volumes greater than 1 TB. The BSD label cannot handle such large disks. Instead, if you are just using the disk for data you can newfs /dev/mfid1 directly and use it as a filesystem, or if you need to partition the disk you can use gpt(8) to do so. If you need to boot from such a large disk you will need to use the GPT boot code in HEAD (I will backport it to 6.x and 7.x soon). I've successfully used it to boot on 2 TB mfi(4) volumes. Unfortunately sysinstall doesn't support GPT at all, only the older MBR + BSD label method. Note that this problem has nothing to do with mfi(4) at all, but it is a limitation of the BSD label + MBR that applies to any volume = 2 TB. -- John Baldwin ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Hi John, It seems that the problem is exactly as you described as i was able to get everything working setting 2x146 disks as RAID1 and 4x146 as RAID5.

Seemed to work just fine. I haven't got any PERC6/i's in production at this stage so can really say about their stability/performance just that they appear to work just fine with the 10 minute test I just did.
