Hi, 0. I have two hosts running debian jessie from /dev/sdb. 1. I followed the user guide and created a drbd resource directly on a partition (/dev/sda1). 2. On top of my resource (/dev/drbd2), I created a LVM volume group (VG1) and a logical volume (data2). I created an ext4 filesystem on data2. Step 1 was done on two hosts (proxmox2, primary and proxmox3, secondary). Step 2 was replicated by drbd from proxmox2 to proxmox3 with the exception that the entries under /dev were not (/dev/VG1 and /dev/mapper/VG1-data2). While fiddling and trying to find a way to create the entries under /dev on proxmox3, I tried to demote proxmox2:data2 from primary to secondary but it complains that root at proxmox2:# drbdadm secondary data2 data2: State change failed: (-12) Device is held open by someone Command 'drbdsetup secondary data2' terminated with exit code 11 The user-guide covers the early steps but ignores the complications. I am new to drbd but I'd be willing to contribute to a more complete user guide if I manage to finish my configuration ;-) Cheers. Marc
