Yes, it is possible. The way to do it is to create an Ignite make_tape_recovery backup, then boot from the tape, size your logical volumes as needed and then finish reloading your system.

However, the root partition should be static and not growing. If it is growing, then the better approach is to find out why and fix the problem.

The root partition is full because mistakes have been made. You'll need to find the big directories (not necessarily big files) and put the files in the right location. Use these commands:

ll -d /* | sort -rnk5 | head -20
du -kx | sort -rn | head -20

Post the results and we can show you what should be moved or removed. As a hint, /dev must never be at the top of the list, only /etc and /sbin.

Hi,

So many discussions on root full:

etc etc etc....
Or search forum with root keyword... You will get whole list.

Bottom line of all threads is:

Root should be static
Application writing to / sholud allocated with dedicated FS.
Free up space by removing olg log, crash, tmp files before you attempt for extend.
/ extend on the fly is not possible
You should hold firm backup if you attempts for the same.

The temp. solution would be , try to find the large files and trip it

find / -size +50000 -xdev -exec ll {} \;

null those files, if they are log files which are not required.

Look for a large text file in /dev - a common mistake is mistyping a tape device name. There should not be any ordinary files in /dev.

Actually, you can extend / on the fly while the system is up if the following conditions exist:

1. You have OnlineJFS installed.
2. There are contiguous extents available on the root disk that contains /dev/vg00/lvol3 (/) since / must be contiguous.

I have done this on 11.23 systems where / filled up without any downtime.
