Just a small drop-in: I have a Promise FastTrak133 with two Maxtor HDDs attached to it, and running smartmontools every 5 minutes, didn't notice any troubles or signs of instability. And, about data recovery, if there are two failing HDDs in a RAID5 array, and you had nr-spare-disks equal to zero, I *think* there is no chance to revover your data, because RAID5 is protecting you against at most one HDD failure. If I'm wrong, please correct me. ;) -- .----------------------------------------------------------------------------. | Pozdrav / Best Wishes, dsimic@urc.bl.ac.yu | LL The Choice of | | Dragan Simic RS.BA Hostmaster | LL GNU | | URC B.Luka / RSKoming.NET System/Network Admin | LLLL i n u x Generation | `----------------------------------------------------------------------------' - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
