Increase space in /var
Hi

Please can I have some help in increasing
Code:
/var

in my
Code:
solaris 10

server.
At the moment the size configured is small and I need to expand it:

Code:
 df -h

How is this disk partitioned?

It looks like /dev/dsk/c1t0d0s4 isn't currently mounted. Can you expand slice 3 to add the space currently allocated to the slice 4, or is slice 4 being used but just not currently mounted?

s4 is probably empty (not used).
In order to give a suggestion for expanding partitions, we need your partition map
Code:
/usr/sbin/prtvtoc /dev/dsk/c1t0d0s0

Hello!

this is my partition map:

*   14087 accessible cylinders

* Flags:
*   1: unmountable
*  10: read-only

There are no unused blocks on your disk; all blocks are allocated to existing partitions.

If you want to increase the size of /var and you want to keep it on this disk, you'll have to back up all of the partitions on your disk, reformat it with a larger partition for /var and a smaller partition for one or more of your other filesystems, and then reload the partitions you modified from your backups.

Thank you very much, I will do that,

But tell me what about space in slice 4?
# 7  
Old 01-08-2016
Slice 4 isn't being used, but to make it part of /var it would have to contain blocks adjacent to slice 3. You could merge slice 0 and slice 4 to grow /, but you can't use the blocks in slice 4 to grow slice 3.

You could move slices 0 and 1 to use lower numbered blocks (keeping the same sizes) and and expand slice 3 using blocks no longer being used at the end of the current slice 1 to expand the start of slice 3.
