Hello linux-raid, I have tried several cheap RAID controllers recently (namely, VIA VT6421, Intel 6300ESB and Adaptec/Marvell 885X6081). VIA one is a PCI card, the second two are built in a Supermicro motherboard (E7520/X6DHT-G). The intent was to let the BIOS of the controllers make a RAID1 mirror of two disks independently of an OS to make redundant multi-OS booting transparent. While DOS and Windows saw their mirrors as a singular block device, Linux (FC5) accessed the two drives separately on all adapters. Is this a bug or a feature of the kernel driver support? (I did not try vendors' binary drivers, if there are any). -- Best regards, Jim Klimov mailto:klimov@xxxxxxxxxxx - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
