It's not easy to say something useful here but maybe this: don't panic
now! It's my experience that in critical situations it's VERY important
not to get nervous an mess things up.
I'm just wondering whether your filesystem corruption is related to the
disk crash. If yes, it means the 3ware controller did not do his job. So
if it's like that I would not trust it anymore and I suggest NOT to
replace the broken disk immediately. If you replace the disk and the
3ware doesn't start up correctly, you may loose all data.

I think your unmounting problem may be related to knfsd. I have a server
running samba and knfsd for several HP/UX, Solaris, Linux and Windows
clients and on this machine I have never been able to unmount /home. I
went to single user, tried to find any files with lsof, removed all nfs
related kernel modules but still could not unmount it. I'm just
wondering what will happen if I have to shutdown it, it has 249 days
uptime and it's a quit busy server on Mandrake 7.0 / 2.2.14 with ext2fs.
