Fact is, asking a broken drive to do SMART stuff may be the straw that breaks the camel's back. Immediately upon using smartctl -a, /dev/hde started making repetetive clicking sounds every half second or so, and the ide driver spammed syslog spectacularly. It's only worked sporadically since (no more than a few minutes at a time), even when power-cycled. > with a promise controller and maxtor disks. i used to query the SMART oddly enough, it _is_ a maxtor disk on a promise controller (PDC20626, I believe). > i've since switched from promise to 3ware, and now i can't use smartctl to > query the data.

I've heard noises about 3ware support in very recent releases of smartmontools, iirc. > mdadm can do it for you ... you need to know exactly which disk was in > which position in the raid. then you recreate the raid using "missing" in > the slot where /dev/hde belonged. then you'll have a degraded array, so > md won't try rebuilding it. then you can copy off the data. seriously? Did you read the whole thread? mdadm will do the right thing even though /dev/hdg was 3% into a resync when /dev/hde died? That would be lovely. > you need to know the exact numberings, and the exact commands you used > to create the array in the first place. How might I go about figuring this out? I got a 120G drive yesterday that's large enough to capture raw images of all the raid disks, so I can try different combinations of commands. What I can't do is look at the logs, because the non-raid portion of the now-dead /dev/hde held the root, /usr, and /var partitions.
