Hello Linux RAID,
One of our servers using per-partition mirroring has a
frequently-failing partition, hdc11 below.
When it is dubbed failing, the server usually crashes
with a stacktrace like below. This seems strange, because
the other submirror, hda11 is alive and well, and this
should all be transparent thru the RAID layer? This is
what it's for?
After the reboot I usually succeed in hot-adding hdc11
back to the mirror, although several times it was not
marked dead at all and rebuilt by itself after reboot.
Also seems rather incorrect: if it died, it should be
marked so (perhaps in metadata on a live mirror)?
Overall, uncool (although mirroring has saved us many
times, thanks!)
