Re-size root

Hi Experts,

Could you please explain how to resize root file system through Ignit backup?. I have enough space on my VG to extend the root, but i request for the steps.

I know to take backup of root through "make_tape_recovery –AIv –d /dev/rmt/0m", i need the steps after this.

Thanks in advance

Re: Re-size root

Hi:

# /opt/ignite/bin/make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn

This will make a recovery tape of the entire contents of vg00. The '-I' option will provide an interactive prompt when you boot from the tape.

Put the tape in the tape drive and reboot. Interrupt the boot process during the 10-seconds you have to interact with it. Search for sequential media representing the tape and boot (again) from that. Specify "N" when asked to interact with the IPL.

When Ignite loads, choose a Media-Only instatllation and select the Advanced mode. This allows you (via the Filesystems tab) to specify the size of the logical volumes of vg00.

Be sure to select only one disk as your boot disk. This is done via the "Add/Remove Disks" when you have visited the Filesystem tab. Ignite will warn you that you have an LVM signiture on your current boot disk, but you will undoubtedly want to use that again. Hence, ignore the warning.

On the System tab, there is a question of when to collect your final system parameters (i.e. IP address, hostname, DNS server, etc.). My preference is to toggle "Ask at first boot" which causes '/sbin/set_parms' to run after the first of two reboots.

You can choose (or not) to import your non-vg00 volume groups using the "Additional" link on the "Basic" tab.

Regards!
