I have an ubuntu installation, 10.10 currently, with a rocketraid 1742 card, 4xSATA300 expanded to a few esata boxes. I used OCE to grow the softraid from 6 drives to 7. Linux sees the disk, showing approximately 1TB of unused space.

When I setup the raid, I setup an XFS partition using all possible space.

Without destroying the data, how can I grow the partition to use all possible space on the disk now?

I've read where you need xfs_utils and the xfs_growfs command. I've run that, with -d tag to 'grow' and used various commands to try to specify block size manually. No matter what I put in, it gave a response :


meta-data=/dev/sdb1 isize=256 agcount=7, agsize=183127946 blks
= sectsz=512 attr=2
data = bsize=4096 blocks=1220853646, imaxpct=5
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0
log =internal bsize=4096 blocks=32768, version=2
= sectsz=512 sunit=0 blks, lazy-count=0
realtime =none extsz=4096 blocks=0, rtextents=0
data size unchanged, skipping

any and all help is appreciated!

Are you using the same partition table? (/dev/sdb1 the same as before?) In this case you might try gparted.

thanks for your reply.

i believe one of my initial tries were to use gparted. under /dev/sdb1 in gparted, it shows an 'unallocated' 1tb space. this is how i assume it should show. the only options for the drive, however, is information and manage flags and unmount. checking gparted's list of 'supported filesystems' xfs support is checked under GROW on xfs.

even an unmount does nothing to allow resize to be available.

I found this post but the steps are quite scary (recreating partition table!):

not sure if you really want to try it
