Thanks for that... To confirm the RAID1 matters because RAID 10 is RAID 0 (stripe) over RAID 1 (mirrors)? I don't mind having to revert to BIOS for rebuild in the event of a hd fault, but I wouldn't mind understanding a little more about the lack of error handling. Do you mean if one disk in the underlying mirror set fails that dmraid will 1) ignore and not notify 2) fall over in a big heap 3) notify, keep running but not rebuild 4) not handle inconsistencies without reversion to BIOS? 2008/5/16 Daniel O'Connor <darius@xxxxxxxxxxx>: > On Fri, 16 May 2008, Jonathan wrote: >> >From my understanding the RAID should be supported by dmraid ok >> >> 1) Is this correct? >> 2) Will it work "out of the box" or will I need to do complicated >> things? ;) 3) Anything I should know?
