This isn't weird. By using 'atacontrol create' yourself, you have a pure-software RAID same as you would have with ccd(4). The difference from defineing it in your software-assist "RAID" BIOS is that you can boot off the RAID. With the pure-software RAID you cannot[*].
[*] Unless your PATA/SATA "RAID" controller just happens to understand the metadata used by 'atacontrol create'. A 'atacontrol create' RAID1 (mirror) might also be bootable, I'm not sure about that; but a RAID0 (stripe) certainly isn't. There are many new SATA "RAID" controllers that our ATA driver doesn't yet understand the metadata. Soren is working on support for these newer chipsets. -- -- David ([EMAIL PROTECTED]) _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
