atacontrol.c commit on 25-Jan-2006, lines 413-427. Code was added to allow creation of RAID0+1 on ATA controllers available at the time. This code is checking for the user supplied strings "RAID0+1" and "RAID10" and treating them both the same. As a result, RAID10 arrays cannot be created on devices that support both levels -- unknown if there are any such devices supported by atacontrol. RAID10 and RAID0+1 are not the same thing. The comment in the commit implies that the author thinks they are. >How-To-Repeat: >Fix: 1. On controllers only supporting one of the two levels (0+1 or 10), display and expect the correct string. 2. Separate the two so that, if there are any controllers that do support both, the correct one can be chosen. ata_ioc_raid_config in sys/sys/ata.h will also need modified to support both AR_RAID01 and AR_RAID10. >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
