Ah, yeah, that looks bad to me. And since it is on a write, that probably means the drive has also ran out of the sectors it has reserved for automatically replacing failed ones. You could probably run some additional tests using smartctl, but I think it is probably just time to get a replacement drive.
Does all of this suggest a complete and total drive failure? :-) I orginally built this md4 array as a Raid 5 from three of the cheepest drives that I could find (Maxtors). Then a couple of months later, one drive died. So I converted the remaining to into a raid 1. Now this one seems to have died. I guess I am learning my leason about buying cheep hardware. Fortunately I have a back-up of everything on this array.
Yeah, probably. I don't know why exactly, but it seems quite common that when you buy several drives of the same make/model at the same time (and thus, they probably come from the same lot), if one fails, you can expect others to fail soon afterwards. It seems like you are better off buying from different manufacturers in this case. -Richard -- gentoo-user@gentoo.org mailing list
