MySQL How to grow my files System?
Dear Gurus of Unix.
When I Put this command:
Code:

I observe that my Hard Disk has 40GB
but when I run this command
Code:
# df -h

/dev/dsk/c0d0s0        494M   410M    34M    93%    /

#

I observe that I only use 16 GB

The question is:
Why I have three files System with the same name swap?
Code:
# df -h | grep swap
swap                   153M   896K   152M     1%    /etc/svc/volatile
swap                   610M   458M   152M    76%    /tmp
swap                   152M    24K   152M     1%    /var/run

and how to use all 40 GB of my hard disk?

Regards
Andres

Not direct answer, but some pointers to proceed.

1. What is swap space: All about Linux swap space | Linux.com

2. Check whether you have partitions ... with those 40 gig, or search about linux partitioning..
if already created, then you can use those ... how ? by creating files and directories in those partitions ...

This is a Solaris system, not Linux. So don't get bogged down over the specifics of Linux swap - it's the concept that's important.

The reason you see "swap" for those file systems is Solaris uses swap for those file systems - they're effectively temporary RAM disks.

And that looks like just about the worst Solaris disk partitioning I've ever seen. If there's an available slice, you can perhaps create a new file system on that slice and somehow use it, but it won't be easy. If possible, you'd be better served doing a clean reinstall and repartitioning your disk with something like 4 GB of swap and the rest all in the root file system.

Because unless you have other reasons for partitioning your file systems (for example, like wanting a separate /var file system so logs don't fill up your root file system), it's a lot easier to manage if you just give the whole disk to /. Splitting the disk into multiple partitions is likely to make whatever space issues that do pop up appear sooner as they have a smaller dedicated partition.

check using the format command.
Code:
# format c0d0s2

check if you still have unused space that you can assign to slice 4.

is there a reason because you have that much slices???
my suggestion is to create a flash-archive and rebuild your server with a new slice-concept ;-)

This may help you understand Solaris virtual file systems (They used be called pseudo file systems) and why thy use swap space if it is available: http://download.oracle.com/docs/cd/E...dl0/index.html.

As for reducing the number of slices or the claim that this is a worst disk partitioning scheme, I respectfully disagree. I suggest that you read http://download.oracle.com/docs/cd/E...dks/index.html

Note that if you are running on x86, not SPARC, there might be other primary partitions than the Solaris one on that disk. You should try by figuring out that first before fiddling with slices.
