<div dir="ltr">Hello drbd community,<br><br>I am currently installing drbd9 with Proxmox 4.4. <br><br>The architecture is as follows:<br>- 2 servers (pve1 & pve2) cluster for Proxmox and a PC (pve3) to establish the quorum for proxmox cluster. <br>- On the 2 servers (pve1 & pve2), drdb9 is installed<br><br>On pve1, I initialised the drbd9 cluster and I added the pve2 (drbdmanage add-node command) to form the DRBD9 cluster. <br>I created a virtual machine 100 on pve1 and the volume vm-100-disk1 was created. <br><br>The results drbd-overview on nodes pve1 & pve2 are as below:<br><br>root@pve1:~# drbd-overview <br> 0:.drbdctrl/0 Connected(2*) Primar/Second UpToDa/UpToDa <br> 1:.drbdctrl/1 Connected(2*) Primar/Second UpToDa/UpToDa <br>100:vm-100-disk-1/0 Connected(2*) Primar/Second UpToDa/UpToDa<br><br>root@pve2:~# drbd-overview <br> 0:.drbdctrl/0 Connected(2*) Second/Primar UpToDa/UpToDa <br> 1:.drbdctrl/1 Connected(2*) Second/Primar UpToDa/UpToDa <br>100:vm-100-disk-1/0 Connected(2*) Second/Primar UpToDa/UpToDa <br><br>The following scenario was tested: <br><br>1.
When all nodes are running, I can migrate the virtual machine (both
online and offline) from pve1 to pve2 and from pve2 to pve1. <br><br>2.
When the virtual machine is on pve2 and I shutdown the server pve2, I
am able to move the container manually from pve2 the node pve1 and start
it. This works well and the volume vm-100-disk1 changed its state from
the secondary state to primary. <br><br>3. When the virtual machine is
on pve1 and I shutdown the server pve1, I am able to move the container
from node pve1 to pve2 but unable to start it. Moreover, the drdb
storage becomes unavailable and the drbd quorum is lost. <br><br>The log below error was found in the log: <br>Mar 11 21:52:19 pve2 pvedaemon[1291]: <root@pam> starting task UPID:pve2:00001695:00022F2F:<wbr>58C43953:vzstart:100:root@pam:<br>Mar 11 21:52:19 pve2 pvedaemon[5781]: starting CT 100: UPID:pve2:00001695:00022F2F:<wbr>58C43953:vzstart:100:root@pam:<br>Mar
