Ignite image

[panks]

Hi I tried to take the ignite system image of my server using make_net_recovery and it is failing due to insufficient space in /var. I have 8 GB of free space in /var but it is asking for 15GB of free space. I doubt how could be the sytem image is so big. One more thing it is happening for all my servers, so I am noty able to take their system image.

hi,

it does seem alot to ask for, but that depends upon the archive trying to be created. Something that size is going to take a long time to create and restore if needed.

Ignite is really meant just to create a system image of just you system and some software and config files, not your whole system and your users home directories full of there data for example.

what was the command used? useful to know what was included or excluded from the archieve? and also the size of the system your archiving?

I have used
/opt/ignite/bin/make_net_recovery -s -x inc_entire=vg00

This command.
My requirement is in case of system crash I should be able to recover it using this system image. I dont want to backup user data but I want to backup all the system config and the drivers that has been installed for SAN devices etc.
I short my system should be ready fro use and from there user can start restoring his data which is backed up on the tape devices through netbackup.

Can you provide a bdf so we can see how much is in vg00?

>My requirement is in case of system crash I should be able to recover ...

This seems the main purpose of ignite.

8 GB is very small for an Ignite network server. The amount of space you need depends on the command line you used to create the archive. First make sure you are using -x inc_entire=vg00 and do not use -A. Then add up the used column for all vg00 filesystems. It probably adds up to 15 GB. You could exclude /home but even this would not work eventually as other directories continue to grow.

A typical Ignite network server will have a separate disk volume for /var/opt/ignite, perhaps 200 to 500 GB. While you can save just one Ignite image, you may benefit from having at least 3 or 4 copies, especially when patching or significantly changing your system.

Hi,

Most of the time /home is huge size in that case you can exclude /home and take the ignite backup and take /home backup separately into other tape or other media.

make_tape_recovery -x inc_entire=vg00 -x exclude=/home
