Thanks Phil,
fsck is finding lots and lots of problems. Figure I'll just run fsck -p
and see what happens... not sure what choice i have...
examine output attached here...
Re re-growing, I was hoping that running on a newer mdadm (4.1) might
fix the problem, and if i still encountered it, perhaps running the
following might unstick it:
echo frozen > /sys/block/md0/md/sync_action
echo reshape > /sys/block/md0/md/sync_action
But, I personally have no idea what happened (really), nor why... :-(
thanks,
allie
