I've got an (externally hosted) production server running Ubuntu LTS. It serves webpages (rails) and has an svn repository accesible through Apache, and a PostgreSQL db.

I've got ssh access to the server and root privileges.

Most of the "interesting" stuff is located in /var/ : svn repositories are inside /var/svn, web pages under /var/www, etc.

Yesterday I was curious about how much disk space had it left, so I did the following:

$ df -h

Filesystem            Size  Used Avail Use% Mounted on
/dev/md1              950M  402M  500M  45% /
varrun                990M   64K  990M   1% /var/run
varlock               990M     0  990M   0% /var/lock
udev                  990M   76K  989M   1% /dev
devshm                990M     0  990M   0% /dev/shm
/dev/md5              4.7G  668M  4.1G  15% /usr
/dev/md6              4.7G  1.4G  3.4G  29% /var
/dev/md7              221G   28M  221G   1% /home
none                  990M  4.0K  990M   1% /tmp

My 'var' partition, which holds most of the interesting part, is only 4.7G big. The /home/ partition, on the other hand, is 221G, but it is mostly unused.

I should have checked the disk layout before starting installing stuff.

Ideally I would need /var/ and /home/ to be "switched" - /home/ should be the one with 4.7G, and /var/ the one with 221G.

Is there a way to solve this without having to reinstall the whole thing?
