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.

Five models include cards with four, eight, 12, and 16 internal ports, plus one groundbreaking SKU with eight external ports and dual path failover. The new controllers support RAIDs 0, 1, 5, 10, 50, 5EE, and the patented RAID 6/60, which Adaptec says can survive two simultaneous drive failures. investor.adaptec.com/ReleaseDetail.cfm?ReleaseID=233555 investor.adaptec.com/ReleaseDetail.cfm?ReleaseID=233556 http://www.processor.com/editorial/article.asp?article=articles%2Fp2912%2F02 p12%2F02p12.asp&guid=&searchtype=&WordList=&bJumpTo=True http://tinyurl.com/2kdzcb ^ permalink raw reply [flat|nested] 4+ messages in thread

Is no news good news? No, no news is no news. If someone has a patent, then that might be nice for them, but is of little interest to me. If anyone takes patent action against any one about any code in the kernel (or elsewhere in widely used FLOSS code) then that is a concern to lots of people and (providing it becomes know) I suspect that a lot of people will take interest. However unless and until that happens, my personal attitude to other people's patents is that they aren't my problem. BUGs are my problem not patents.
