Help with Software RAID needed

2011-04-23 Thread Jo Galara 
I just got my new dedicated server, running Debian Lenny 64bit.
It has 2x500gb Software RAID but df -hT only shows a few GB for each
partition:

# df -hT
FilesystemTypeSize  Used Avail Use% Mounted on
/dev/md1  ext33.7G  339M  3.4G  10% /
tmpfstmpfs2.0G 0  2.0G   0% /lib/init/rw

/dev/mapper/vg00-home
   xfs4.0G  4.2M  4.0G   1% /home
none tmpfs2.0G 0  2.0G   0% /tmp




fdisk -l shows the correct sizes:

How can I increase the size of the partitions?

You're using LVM. What does
# pvdisplay

show?
