Well, I just went and set up the system with kernel 2.2.2 (without any extra
patches) and raidtools-0.42, and it does the exact same thing.
It just keeps on accessing the dead drive, with increasing sector numbers in
the I/O error message - sort of like it is trying to continue to flush the
buffer cache or something.
With the 2.2.2 clean and 0.42 it looks like the raid1 module only detects
the failure once, unlike with 0.90 and the current patches for 2.2.0 - with
that combination, it keeps on detecting the failure.
Has _ANYONE_ had any success with this with a 2.2.x kernel?!?!?
It looks to me like if you lose an IDE bus that a drive is hooked up to - it
will never recover, but if you just lose a drive, it will. This seems to be
a major shortcoming, but might be livable. It looks like if I re-plug the
drive back in, it stays degraded, but it does recover and keep on accessing
the raid set.
Is there any chance of getting this thing to recover from a bus failure?
