Hi, I am still pretty new to DRBD and am having some trouble. I was able to successfully load DRBD and run it on my servers a week ago, and the tests ran fine. I tried to unmount one of my filesystems and detach, but got an error, device is busy. I tried to force the unmount by killing the process but that didn't work, so I used the command "umount -l /..." Then when I tried to run "drbdadm down r1" I get this error: /dev/drbd1: State change failed: (-12) Device is held open by someone Command 'drbdsetup /dev/drbd1 down' terminated with exit code 11 Even though I already unmounted it. I don't really know whats causing it, and where to start looking to fix it... Then weird thing is i also have drbd running on another resource, r0, which works perfectly fine, but r1 seems to give me trouble attaching and detaching. Any help would be great. Thanks, Allen
