make one partition with two existing ?

[Frank Bonnet]

Hello

I have a raid 5 array ( HP hardware managed ) that contains the 
following partitions

-- Filesystem       Size    Used   Avail Capacity  Mounted on
/dev/aacd0s1a    1.9G    306M    1.5G    17%    /
devfs            1.0K    1.0K      0B   100%    /dev
/dev/aacd0s1g     10G    7.2M    9.3G     0%    /tmp
/dev/aacd0s1e    609G    559G    1.5G   100%    /mnt
/dev/aacd0s1d     97G     12G     77G    14%    /usr
/dev/aacd0s1f    610G    5.3G    556G     1%    /var

What I would like to do is

1 - delete the /mnt partition
2 - extend the /var partition with the free space left by /mnt

Is it faisable without destroying the /var data ?

Thanks a lot
