The fileserver froze on me this morning, and again this afternoon. Best
guess has always been drive spin-down; this is apparently a known problem
with some newer SATA drives and some older kernel and possibly BIOS
configurations. Various attempts to fix it with hdparm
failed miserably. Installing acpid, while clearly necessary,
didn't help either.
The current attempt uses a newer kernel (2.6.21) from 64studio.com. It certainly improves the
results back from hdparm -i, but it's not clear that I
was able to keep the drive from powering down. We'll see. The fact that
a similar drive has been happy under UbuntuStudio (2.6.22) is
encouraging. I can go that route if I have to; Ubuntu's not that far off
of Debian.
If it stays up for a day or two, I'll start thinking of other places to use the 500GB IDE drive I bought at Fry's on my way home from work. If it doesn't, I get to start thinking of other places to put a couple of 400GB SATA drives. Preferably someplace where I don't mind running a bleeding-edge kernel.
