you might just want to clone stuff to a new, big hdd and start from scratch. that's what i'd do; i'm lazy and it's a pretty complicated and convoluted partitioning/RAID layout you have.

So it seems that I am running a mix oF RAID0 and RAID1 on these two disk
RAIDED sets..
The following is how they are mounted on my system when in use..
Filesystem Size Used Avail Use% Mounted on
/dev/md0 2.0G 374M 1.5G 21% /
/dev/md5 28G 33M 27G 1% /home2
none 1004M 0 1004M 0% /dev/shm
/dev/md3 4.9G 34M 4.6G 1% /tmp
/dev/md4 25G 3.2G 20G 15% /usr
/dev/md2 4.9G 190M 4.4G 5% /var
/dev/sdc2 20G 9.8G 8.6G 54% /mnt
What would you recommend I do at this point to detach sda from sdb so
that I could use disk #2 while still having data preserved on disk#1?
Remeber that I can still boot my system on disk#3 which isn't RAIDED to
anyone..
Thanks for any advice!
Dan
