As I can increase file system /opt

Brian Bergstrand — Thu, 06 Nov 2003 08:56:53 GMT

# bdf /opt

Note the device file from the output

# lvextend -L /dev/vg00/lv???

lv??? will be the device that represents /opt

Now, you will have to boot to single user mode and unmount /opt

# shutdown now

Wait for the transition

# umount /opt
# extendfs /dev/vg00/rlv???

If you have paid for OJFS, you skip the shutdown and unmount and use fsadm to extend the filesystem while it's mounted.

HTH.

if there space on your volume group vg00, then you can increase the size opt file system

Is correct?
First
# lvextend -L /dev/vg00/lv???

Second
Now, you will have to boot to single user mode and unmount /opt

Third

# shutdown -ry 0

Verification increase /opt

hi
1- check if you have space
# vgdisplay vg00
the free space(MB)= Free PE * 4

2- if you have a free space run bdf
to note the device file for opt
bdf | grep opt
you have an output like this:
/dev/vg00/lvolX ??? ???? ??? ??% /opt
3- you can increase opt file system online or you can go to single user mode
online mode
# lvextend -L new_size /dev/vg00/lvolX

#fuser -kc /opt
#umount /opt
# extendfs /dev/vg00/rlvolX
#mount -a

check the new size bdf

ofline follow the procedure of brian

Jose,

what you said is correct as long as you don't have onlineJFS. This product allows you to do this without unmounting the filesystem and without re-booting

check if you have it with "swlist | grep JFS"

Why exactly are you doing this? Is /opt full (or nearly full), or are you intending to install another application under /opt and you don't believe you have the space?

Have you any idea why /opt is full? Has it suddenly become full, or is it just that its grown as you've installed more products?

I usually install applications on their own filesystems mounted under /opt rather than just increase the size of /opt. That way if, for example, an application goes nuts and starts creating huge log-files, it won't affect other applications.

So, the things to consider:
1) Why /opt is full, and how quickly did it fill up. Do you have an application writing stuff there which can be cleared down, or is it just natural growth.
2) Are you installing a new application which will fill up /opt? You can either extend /opt as suggested by others in this thread, or create and mount a new filesystem under /opt and install your application there.

Regards

Col.
