You can probably get your data back... but really you should have
asked for
help as soon as strange things started happening!
Possibly, but I don't like to bother others when I don't need to. And in
the beginning
I didn't connect this behavior whit kernel but with some hardware disk
issues.
Moreover reporting bugs on list is hmm... inconvenient. Please, back
Bugzilla
online ASAP.
If you have all important data backed up then just upgrade to 3.1.2
and make
the array again from scratch.
Probably this is best way...
If you want to try to recover the array please report that output of
"mdadm
--examine" on all of the devices.
...but I paste output of this commands below. If some of system survive,
I can
make it up faster. Of course, if it isn't to complicated or take too much of
your time to describe it.
