I configured my Blade 150 to have RAID1 mirrored system, but I didn't
take all the space yet:
# df -h
Filesystem          Size    Used   Avail Capacity  Mounted on
/dev/mirror/gm0a     19G    744M     17G     4%    /
devfs               1.0K    1.0K      0B   100%    /dev
# swapinfo

So, my question is that what is the correct way to make use of the rest
of the disk space? I didn't find this info in the handbook nor in FAQ.
