I'm able to mount the newest problem child with abort_recovery but not the original trouble maker.  I've made several tries at truncating the last_rcvd file but no luck.  The system has about 30 seconds after being mounted before locking up.

Run "e2fsck -f" when OST is unmounted, using latest e2fsprogs from Sun.
