Did you read the reply I sent yesterday. The problem is that we can't know
how your RAID controller expands an RAID5 array.
If the old device looks like this:
+-----------------------+
+-----------------------+
and after growing it looks like this:
+--------------------------------------+
+--------------------------------------+
then you can use fdisk in expert mode to change the size of your drive in
the partition table and change the partition in this table. Then use
xfs_grows to grow the filesystem on the growed partition.
I don't know how to change the partition table because I have to read the
fdisk docs before I do it.
