I could not reproduce the problem so far. # df -h /mnt Filesystem Size Used Avail Use% Mounted on /dev/drbd11004 600T 534M 570T 1% /mnt # blockdev --getsize64 /dev/drbd11004 659686843969536 # ls -l /mnt total 192 drwxr-xr-x 15 raltnoeder raltnoeder 65536 Jul 3 13:22 drbd drwx------ 2 root root 131072 Jul 3 13:17 lost+found # This was tested with essentially a 9.0.14 version of DRBD, the version that I used had some modifications, but those were not related to the device size. Meta data was created with 1 peer slot. The DRBD resource uses about 20 GiB of RAM when it is active. It will use about another ~19-20 GiB per additional peer slot.
