Can anyone help me about extending the root LVM using the expert recovery shell after boot the system using internal OS DVD?
Currently I dont have any ignite backup.

Re: Need extend root lvm using expert recovery shell
1. Misspelling a backup device, thus filling /dev with a massive file.
2. Using / for general storage or worse, application storage.
3. Defective scripts that create thousands of small junk in /.
So, analyze the root directory and find out why / needs to be larger than 300-500 MB. Use this command:
du -kx / | sort -rn | head -20
The largest directories are at the top of the list. The two largest directories are /sbin and /etc. Here are examples of 4 versions of HP-UX simple installs:
11.00
/etc = 23 MB
/sbin = 11 MB
11.11
/etc = 63 MB
/sbin = 37 MB
11.23
/etc = 190 MB
/sbin = 98 MB
11.31 (PARISC)
/etc = 213 MB
/sbin = 113 MB
11.31 (Itanium)
/etc = 56 MB
/sbin = 170 MB
/dev is always less than 100 KB. IF larger, use this to find the mistakes:
find /dev -type f
No ordinary files are ever to be stored in /dev. If there are large files stored in /, they typically are there because root's HOME directory is /, the worst possible location. The HOME directory for root needs to be moved, along with all the "root-droppings" that are filling the / directory.
>> Currently I dont have any ignite backup.
Don't even think about resizing the root volume without an Ignite backup. All of the procedures to resize the root volume can seriously damage your system.

Re: Need extend root lvm using expert recovery shell
Most probably we will go reinstall the OS then restore all other VG configuration from backup.
But, Thanks all of you for nice post.

Re: Need extend root lvm using expert recovery shell
IF your VG00 is mirrored u can do it online. Procedure attached.
But take the ignite backup before.

Re: Need extend root lvm using expert recovery shell
You should ask him why he wants to increase root FS in 9Gb. He must have its application in dedicated FS other than root.

Re: Need extend root lvm using expert recovery shell
IMHO a totally wrong decision.
All data should be in another VG, not vg00.
Create a new VG on a new disk!
Hope this helps!

If you are the system administrator, remember that you will be blamed for the future problems, long after the SAP consultant is gone and forgotten.
