Check your /etc/ drbdmanaged.cfg file and make sure that the storage type defined there, is configured properly. Is it thin or thick LVM? If it's thin LVM how did you create it ? - The control volume is happy and connected to the other nodes? > > Yes > LV Path /dev/drbdpool/.drbdctrl_0 > LV Name .drbdctrl_0 > VG Name drbdpool > LV Path /dev/drbdpool/.drbdctrl_1 > LV Name .drbdctrl_1 > VG Name drbdpool > root@dmz-pve1:~ # drbdadm status > .drbdctrl role:Primary > volume:0 disk:UpToDate > volume:1 disk:UpToDate > dmz-pve2 role:Secondary > volume:0 peer-disk:UpToDate > volume:1 peer-disk:UpToDate > dmz-pve3 role:Secondary > volume:0 peer-disk:UpToDate > volume:1 peer-disk:UpToDate > root@dmz-pve1:~ # drbd-overview 2>/dev/null > 0:.drbdctrl/0 Connected(3*) Prim(dmz-pve1)/Seco(dmz-pve2,dmz-pve3) > UpTo(dmz-pve1)/UpTo(dmz-pve2,dmz-pve3) > 1:.drbdctrl/1 Connected(3*) Prim(dmz-pve1)/Seco(dmz-pve2,dmz-pve3) > UpTo(dmz-pve1)/UpTo(dmz-pve3,dmz-pve2) > > Yes, control volumes seem to be OK and drbd nodes too, but that's unrelated to the storage which you have dedicated to DRBD (/etc/drbdmanaged.cfg).

This means you need to check drbd pool status, and use drbdmanage add-resource, drbdmanage add-volume commands in CLI to add/remove DRBD volumes. If that does not work, then proxmox gui will not work as well. Y
