Filesystems, Disks and Memory

Below is a list of the file system on my Sun system. How can I transfer more disk space from the "/space" partition to the "/" partition with out rebuilding?

/ /dev/dsk/c0t0d0 6191949 5736718 393312 94%
/proc /proc 0 0 0 0%
/dev/fd fd 0 0 0 0%
/etc/mntta mnttab 0 0 0%
/var/run swap 69922 2 69920 1%
/tmp swap 69922 3 69920 1%
/space /dev/dsk/c0t0d0 12529779 232078 12172404 2%
/home/faculty /export/home/fa 6191949 5736718 393312 94%

Hi,

What do you use for kind of a diskmanager?

Veritas Volume manager ?
SDS/ODS
Or just plain FS ?

df -kl, will let me know what you use.

It's most of all easy to grow an FS, shrinking however is a little harder. Also Online JFS would be something nice to have.
Waiting for your reply.

When this box was built, someone took Sun's default layout. This puts /var, /usr, and /opt all in root. I think that all 3 are a mistake, but /var is especially bad. Anyone can create files in /var/tmp.

Make sure that you don't have a lot of junk in /var. Have you cleaned it up?

Im not really sure what disk manager im using. Here is the output of the df -kl command:

$ df -kl

thanks

Hi,

This shows you that you have no volume manager at all.

It's going to be quiet hard to change this. It can only be done using "format" and increase/decrease the specified slice.

I strongly recommend to not do this. It will not be safe to do. As Perderabo already told. It's not the best install. Please see if you can re-install or else add an extra root-disk.

also Veritas Volume manager should be free of use for the rootdg (rootdisks).

First off what is the best way to check the size of a directory and its content? Secondly what can be cleaned out of /var?

Also, what is the best way to configure the File System when installing a new OS?
