Rodel,

How did the RAID adapter enlarge the partition? In fact partition is not
the right name because it has enlarged the block device on which you
partitions are stored. If it simplay appended more blocks at the end of
the device, you have to modify your partition table to respect the new
physical size. Then you have to grow the partition where you XFS
filesystems sits on. And then, you can grow the XFS filesystem with
xfs_growfs. You can do the first two steps with fdisk, but maybe there is
an easier way. I'm sure there is someone on this list who can tell you
exactly how to do it with fdisk, sfdisk or whatever.
