/opt FS extention

[silusan]

Need to increase /opt file system from 8Gb to 10 GB. Can I do it without unmounting? How do I do it?

Thank you.

If you have Online JFS / Advanced JFS installed on your system, you can do this online.

# lvextend -L 10240 /dev/vg00/lvol5

# fsadm -b 10240m /opt

# bdf /opt 

If you do not have online JFS, you will have to boot to single-user mode, so that /opt is unmounted, and then do the following:

# vgchange -a y vg00

# mount /usr

# lvextend -L 10240 /dev/vg00/lvol5

# extendfs -F vxfs /dev/vg00/rlvol5

# mount /opt

# bdf /opt

The 'bdf' in both steps is just to verify the new size.

To check and see if you have the Online JFS / Advanced JFS license you can try the following:

1) Try the 'vxlicrep' command.  If it is installed you should see something like this --

# vxlicrep

2) Look for the Online JFS bundle of software:

# swlist -l product |grep -i online

3) If you execute the 'fsadm -b' command above and it works, then you have the appropriate software.  If it does not work, then you will have to use the 2nd set of steps above in single-user mode.
