I tried a consistency check of the mirrored set using Windows(!) and motherboard "original" tools; the first time it said that the mirror set was not initialized (I still don't understand how to initialize the mirror using dmraid), while dmraid never reported this "uninitialized" status. I initialized the array and came back to Linux, did some I/O, then checked again and everything seemed fine. dmraid always said "mirror ok". The first time I built the mirros (from the controller's BIOS), I thought a first-time-auto-rebuild would happen in background. Apparently I was mistaken). Now I see those "wrong # of devices in RAID set" messages and feel uncomfortable, afaik they have always been there. My controller: 00:11.0 RAID bus controller: ATI Technologies Inc SB700/SB800 SATA Controller [RAID5 mode] Hope someone can shed some light on this.
