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

Hello *,

I would like to activate DRBD with LVM for online replication.

 

HDD-> LVM-> DRBD is layout of usage LVM together with DRBD

Problem is that after restart drbd is not started automatically
