Re: PARTITION PROBLEM

[Michael Loftis <mloftis@wgops.com>]

This is tricky.  Yes and no.

The RAID5 is hidden by the hardware.  your DISK expanded to 102G, but your 
partitions and possibly your partition table say only 68G.   *IF AND ONLY 
IF (IFF)* the partition you want to expand is not adjacent to (cylinder 
wise) other partitions (IE it is at the end of the disk) you *should* be 
able to change the size of the partition, then use xfs_growfs to make it 
fit the new partition size.

Backup your data first.  It should work OK, but I am in NO way taking 
responsibility if it screws up. ;)
