Hi!
I'm running Ubuntu 7.10 x64. Currently, my system is setup as follows:
- / is in a Raid 1 array (/dev/md0) consisting of two partitions -
sda1 and sdb1 (ca. 148 GB);
- swap in Raid 0 (/dev/md1) - sda2 and sdb2 of ca. 1 GB each giving me
2 GB in total:
- sda and sdb are two disks of 160GB:
- I do not have a separate /home file system.
I would like to correct this situation by doing the following:
- resize the partition containing the / file system to 27 GB keeping
it in RAID 1 (/dev/md0);
- create a new partition of 120GB to mount /home, also in RAID 1 (/dev/md2);
- change swap from a RAID 0 to a RAID 1, resizing it to 2GB (/dev/md1).
Can this be done without reinstalling everything from scratch?

I would really appreciate your help. If you need further info from me
please just say so and I will try to post it as soon as possible.
Thanks.
