Hi Manoj,

Please check what are the big files by below command and remove if not required,

#find /opt -xdev -size +50000 -exec ls -s {} \; |sort -n

Change this "+50000" as requirement
Hope this resolves ur issues

>Which one I can remove from these?

You can't. If you are out of space in /opt, you have to make more. Or create symlinks to other filesystems.

Otherwise you have to remove complete products.

if space is there in the vg then extend 200/300mb as per req.

Hi Manoj,

As Dennis suggested, do not delete files under /opt without removing the products, it could lead to things getting out of your hand.

Thanks

/opt consists of applications as a whole. Try not to remove anything in /opt.

Extend the size of the filesystem /opt with lvextend, fsadm. If you remove things from /opt, then you would have unwanted things under /etc/opt and /var/opt. Hope this info helps.

#vgdisplay vg00
calculate free space (free PE*PE size).If space is there in the vg then extend it.
check online JFS is there or not.If online JFS is there then you can do it online.

#lvextend -L XXXXM /dev/vg00/lvname
(XXXXM stands for the size in Mb)
#fsadm -F vxfs -b XXXXM /opt

Hey;

Another approach is to examine why the space utilization in /opt is growing. That should be pretty stable filesystem. If you're adding s/w products, then you probably need to grow the filesystem - that or remove any unneeded apps via swremove.

If you're *not* adding s/w and the space utilization is growing, then you need to find out which files are the ones growing. People have shown find commands to tell you which files are the largest - other arguments to find will tell you which files have been modified in the last X days:

find /opt -xdev -type f -mtime -7 -print

for instance will find all the files under /opt that have been modified in the last seven days.

HTH;

Hi all,

Thanks for the reply.

I just wanted to know whether i can delete any files from /opt without disturbing the running system.

Increasing fs is not in the consideration.
