I have a machine that has 4 disks in a raid 10 using md. The machine
went through an unclean shutdown yesterday and when the box came up, I
saw errors like the following in the kernel log and the array no longer
[ 28.575149] md: raid10 personality registered for level 10
[ 28.610827] md: md0 stopped.
[ 28.688678] md: bind<sdu1>
[ 28.688981] md: bind<sdv1>
[ 28.689269] md: bind<sdw1>
[ 28.689566] md: bind<sdx1>
[ 28.689748] md: kicking non-fresh sdw1 from array!
[ 28.689890] md: unbind<sdw1>
[ 28.690036] md: export_rdev(sdw1)
[ 28.690175] md: kicking non-fresh sdv1 from array!
[ 28.690316] md: unbind<sdv1>
[ 28.690452] md: export_rdev(sdv1)
[ 28.690589] md: kicking non-fresh sdu1 from array!
[ 28.690730] md: unbind<sdu1>
[ 28.690866] md: export_rdev(sdu1)
[ 28.704706] raid10: not enough operational mirrors for md0
[ 28.704706] md: pers->run() failed ...
Anyone have some suggestions on what can be done to get the array
working again? There are a lot of virtual machines that are on the array
that I really don't want to have to go through and rebuild. Thanks in
advance for any advice you guys have.
