I've finally finished deleting all those nasty unreliable Seagate drives
from my array. During the process I crashed my server - over, and over,
and over. Completely gone - screen blank, controls unresponsive, no
network activity (no, I don't have root on btrfs - data only). Most
annoying, but I think btrfs survived it all somehow - it's scrubbing now.
Meanwhile, I did get lucky: At one crash I happened to be logged in and
was able to hit dmesg seconds before it went completely. So what I have
here is information that looks like it'll help you track down a
rarely-encountered and hard-to-reproduce bug which can cause the system
to lock up completely in event of certain types of hard drive failure.
It might be nothing, but perhaps someone will find it of use - because
it'd be a tricky one to both reproduce and get a good error report if it
did occur.
I see an 'invalid opcode' error in here, that's pretty unusual - and
again it even gives a file name and line number to look at. The root
cause of all my issues is the NCQ issue with Seagate 8TB archive drives,
which is Someone Else's Problem - but I think some good can come of
this, as these exotic forms of corruption and weird drive semi-failures
have revealed ways in which btrfs's error handling could be made more
graceful.
Meanwhile I remain impressed that btrfs appears to have kept all my data
intact even though all these issues.
