Re-allocate disk space
I am running out of space, and would like to reallocate some "wasted" space.

Here is what I see:

Code:
> df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/dsk/c0t0d0s0     5.4G  4.5G  860M  85% /
swap                  2.0G  1.3M  2.0G   1% /etc/svc/volatile
swap                  2.0G  432K  2.0G   1% /tmp
swap                  2.0G   40K  2.0G   1% /var/run
/dev/dsk/c0t1d0s7     8.4G  515M  7.8G   7% /home
/dev/dsk/c0t0d0s7     2.1G  1.5G  483M  76% /export/home

I do not need the information or partition of: /dev/dsk/c0t1d0s7 8.4G 515M 7.8G 7% /home

But I do not want to lose the info or reformat the entire machine.
Is there a way I can edit the vfstab or are there and utilities I can use to get rid of /dev/dsk/c0t1d0s7 /home and reallocate it between my slice0 and slice7 /export/home ?

Code:
"vfstab" 13 lines, 479 characters 
#device         device          mount           FS      fsck    mount   mount

Incredible, the OP isn't using SDS so most of the information in the link you posted is irrelevant.
Ippy98, it is probably possible to growfs s0 assuming s7 is contiguous to it, which it is likely. However, that operation is pretty risky for anyone not familiar with the process so I would suggest you to first make sure you have a reliable backup.

Was a good thought, but doesn't look like growfs will work either Smilie

The following conditions prevent you from expanding file systems:
When acct is activated and the accounting file is on the target device.
When C2 security is activated and the logging file is on the target file system.
When there is a local swap file in the target file system.
When the file system is root (/), /usr, or swap.

This doesn't prevent to grow root (/). You simply need to boot using another root device. The simpler is booting on an installation CD/DVD.
