[wellylug] Where's my disk space gone revisited...

[Andrew Presant]

Thanks Chris,

I *think* I follow what you're doing, but I problem is I need to increase
the size of /var at the expense of /home and/or /usr

 Filesystem          1K-blocks      Used      Available  Use%   Mounted on
 /dev/hda5            505605    221997    257504     47%   /
 /dev/hda1            101089     22035       73835    23%    /boot
 /dev/hda3          4648896     34632    4378112     1%    /home
 none                     61048            0       61048     0%   /dev/shm
 /dev/hda2        12697360   4535656   7516696   38%    /usr
 /dev/hda6          1027768    850556    125004    88%   /var

Would your suggestion do this? I can't see it working as you seem to be
making a new partition, or am I missing something?

The only effect the current situation is having is I can't update the system
due to a lack of space on /var (for Red Hat up-to-date). The machine is a
just a web-server.

Making a guess I need to substitute /usr and /var/spool/up2date for your
examples... And remove the old /var/spool/up2date? Correct?

Cheers
Andrew
