DRBD9 Status - With Proxmox 4.1.22

[mliebherr]

Hello,

i have a 3-Node Setup. Oversudden i can not create new vm anymore. The error is:

TASK ERROR: create failed - drbd error: Not enough free space

See my screen shots attached.

If i sum up all the disks, i should have 849GB used. But my drbdpoll is 2.46TB big.

root@node01:~# vgdisplay

Where does proxmox get the drbdpool size from? Something seems to be wrong here.


** UPDATE **

root@node03:~# drbdmanage list-nodes
+---------------------------------------------------------------------------------------------+
| Name | Pool Size | Pool Free | | State |
|---------------------------------------------------------------------------------------------|
| node01 | 2571264 | 2075781 | | ok |
| node02 | 2571264 | 10027 | | ok |
| node03 | 2571264 | 0 | | ok |
+---------------------------------------------------------------------------------------------+

Looks like node03 Pool Free is zero. I wonder why? How can i look this up?

Thanks,
Michael

*** UPDATE2 ***

lvresize --poolmetadatasize +512M /dev/drbdpool/drbdthinpool ; drbdmanage update-pool

on all nodes seems to help. But i dunno if this is the way to fix it :-(
