after installation I first wanted to test the failover by taking one LUN away from the system. So far i have NOT replicated the /boot sector via sfdisk to /dev/mapper/LUN2_part1, but I think for this scenario this should not be necessary
when I take /dev/mapper/LUN1 away from the system (where the /boot sector ist), everything works fine. I can still write files to the file system and i can still do commands in my ssh session. Then I gave the system /dev/mapper/LUN1 back. Now I wanted to test to take away the other LUN and just reboot the system - this is where I fail.
when I take away /dev/mapper/LUN2, where the /boot sector is currently NOT replicated, ssh freezes and i cannot state any commands.
