Solaris

I dont have much experience in moving slices, or SVM, so I am bit reluctant to do that on a production server....

What is stopping you to create a virtual machine and learn ?

they will give me an old v240 SUN server, and I will try on that

If there is a large directory hierarchy under /var, you could also use the existing slice 4 as /var/subdir (splitting /var into two filesystems). Note that this will only work if there are no hard links between files under /var/subdir and other parts of /var.

Mount slice 4 as /x, copy the current /var/subdir file hierarchy to /x, move /var/subdir to /var/oldsubdir, unmount /x, mount slice 4 as /var/subdir, resolve any differences you find between /var/oldsubdir and /var/subdir (which would only happen if files were being updated in /var/subdir while you were copying the old /var/subdir to the newly mounted partition), and then rm -rf /var/oldsubdir to free up the space that is now duplicated elsewhere.

Attention! s4 is marked with a flag, check with

Code:

swap -l

if it's used as a swap area.
If yes, you may not use it!!
Actually I would look if you can sacrifice the /export/home partition, this seems hardly used and over-dimensioned.

Is there more than one disk in that server? If so, you can use "liveupgrade" to create a new disk layout and after one reboot you are done with resizing everything to your needs...

for swap:

Code:

# swap -l
swapfile             dev  swaplo blocks   free
/dev/dsk/c1t0d0s4   32,28     16 4202672 4202672
/export/home/swapfile  -       16 4194288 4194288

two disk on the server
