[WBEL-users] Resizing RAID devices

[Alon]

Looking at my available space on the server, I see that I'm reaching levels 
that are somewhat troublesome.
/usr
has 6GB of 'leftovers' so it could be nicely be pushed to /backup  (/backup 
holds two days back of /home and /var).


Filesystem            Size  Used Avail Use% Mounted on
/dev/md0              981M  279M  653M  30% /
/dev/md5               26G  9.5G   15G  40% /backup
/dev/md4               26G   12G   13G  50% /home
none                 1000M     0 1000M   0% /dev/shm
/dev/md3              2.0G   69M  1.8G   4% /tmp
/dev/md1              9.7G  1.7G  7.6G  18% /usr
/dev/md2              9.7G  3.2G  6.0G  35% /var


Is it possible to resize the partitions?
I don't mind rebooting from a setup disk if needed, I just never resized 
using a diskdruid or alike.
If this is possible, I need to resize both HDs' partitions to match. (both 
HDs are of 80GB SATA).
the question is, do I do that as RAID devices or do I need to remove the 
RAID configuration and then do a resize on each one of them?
