RE: XFS on x86_64 Linux Question

["Daniel Korstad" <dan@korstad.net>]

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. 

 

Dan.
