[DRBD-user] Problem with drbd and lvm

[Alireza Nematollahi]

You can do BASH scripting...You can easily write a script to load DRBD module on startup and set it up (i.e. start the process and resources...)
Should be fairly simple. I've done it before.

thanks

Sorry for my mistake
I thought experiences instead of exercise.

Thanks for your information.

vgchange -ay is done in initrd during the booting.
Do you have some exercise with the script which should be written?
What should be written in this script?

Thank you in advance

I think it's because LVM volumes don't get activated on start up automatically. If you do lvscan after restart, you'll see that all volumes are inactive. I don't know if there's any way to activate them automatically, but you can do:         vgchange -ay

Then you can use your DRBD. One more thing. If you want, you can write a small BASH script to do the initializations for DRBD and LVM and put it as part of your Linux startup programs...

Hope this helps
