Extending / filesystem using online JFS

[Sudeesh]

Hello all,

I have a system where the / filesystem is almost 95% used. Can I use lvextend and fsadm the normal way? Or is thr any special procedure to extend root ?

Your help will be much appreciated.

No, the / partition cannot be extended the normal way. / is one of the filesystems that MUST be contiguous.

How big is /. / should NOT normally grow in size. Check your /dev directory and make sure there are no regular files that are very large. A common problem is typing a tape device file incorrectly. Using om instead of 0m for example.

Also try 'du -ksx / | sort -n' and see what it returns.

Hi Sudeesh,

This is not an esay question, yes it is possible but / (root) filesystem needs to be contiguous.

Check this thread for both lvm and ignite options.
