Short answer, yep, I have done it. I don't know exactly what you are looking for, or what tools you need. The follow is my very recent experience. I have a FC4 x86_64 that I have been using for awhile. I have a raided OS (raid 1on using the two separate IDE controllers) and raided data drives (9 in a RAID6 on SATA controllers) I had replace the original OS drives with larger ones. I wanted to take the new larger drives’ capacity and put that in the ext3 fs on the raid 1. Last night I did this on the system; mdadm --grow /dev/md0 --size=max But I had older resize2fs, it does not support ext resize on a live mount filesystem, and since this partition was my / partition... I rebooted my system with knoppix and did; mdadm --assemble /dev/md0 /dev/hda1 /dev/hdc1 fsck.ext /dev/md0 resize2fs /dev/md0 And reboot back to operational without any problems. My data raid6 is on a XFS. It support live filesystem expansion (xfs_growfs while mounted). I have not done anything with my xfs in knoppix but I am sure some tools are in there too. This is not a thorough test of tools on knoppix on my 64bit system but from my experience, I can boot into it and assemble my raid within it.
