Hi Vinay:

The safest way to do this is to take an Ignite backup of your server; boot from the Ignite tape and reinstall using Ignite's Advanced Installation menu(s). You can resize any or all vg00 logical volumes this way quite easily and safely.

Shalom,

1) You can not extend root, it must be contiguous.

2) You can back up your vg00 with Ignite, restore Ignite backup and then intervene and set / larger in the restore.

3) I think if you look around in / you will find something that does not belong there.

I agree with Steve - there must be something in there that doesn't belong. The most famous problem comes from a regular file in the /dev directory, caused when someone mistypes a tape device name during a backup. Check with "find /dev -type f" - you should not see any regular files.

Other than that one common error, you will need to do some careful checking. Run "du -sk /* |sort -n" to see where the most space is used up. Use "find / -name core" to look for coredumps.

The root file system should be relatively static and yours is plenty big enough - you just need to remove some junk that doesn't belong.

Hi ,

Which is your OS version?

As everybody told, the safest method is

1. Check if there any files which can be removed.
2. Taking an restring the ignite backup.

Still there are menthods to extend the root volume.

1. As it should be contigeous, only thing you can do is reduce the size of next volume ( probably /tmp) and increase the /

1. boot in lvmmaitenance.
2. remove /tmp
3. extend /
extend the filesystem
4. recreate /tmp
do lvlnboot
and copy back the backup /tmp if required

Other method is using DRD ( 11.23 onwards)
