Hi All,
I have a problem and I hope that someone can help me.
I have a 3 node cluster with Proxmox 4.4 and DRBD 9.06.1 with
drbdmanage 0.99.4 working in production from 2016 and for some reason I
don't like to update to the new version for the moment .
Now Proxmox is still working but
Hi,
In /var/lib/drbd.d of my DRBD9 nodes there are not only files .res,
like drbdmanage_vm-106-disk-1.res, but also files .res.q, like
drbdmanage_vm-105-disk-1.res.q
What are they and what they are for? Can be eventually manually removed?
Thanks,
Michele
To DRBD's guys:
After removing and restoring one VM (vm106) I found a strange
situation on my 3 nodes PVE with DRBD9
on the Primary node:
root@mpve2:~# drbdadm status
.drbdctrl role:Primary
volume:0 disk:UpToDate
volume:1 disk:UpToDate
mpve1 role:Secondary
volume:0

Thanks Yannis,
unfortunatly drbdmanage resume-all nor drbdmanage restart get no effect.
I'm afraid I'll have to delete and recreate resources...
Why? Have you ane issue with your resources, apoart of "pending actions" ?
Do you think that "pending action" is not an issue?
So I'll try to move the VM's between nodes, just to be sure, and if
it'll work I will leave things as they are...

The same problem I had some days ago creating a KVM on a node not
primary, the creation failed but, after some attempts I found with
"drbdmanage a" 6 disk created and I had to remove them with
"drbdmanage remove-resource -f"
It seems a problem related with the VM creation on node not primary.
So why when I used "drbdmanage remove-resource -f
vm-101-disk-6" and others like this the resources
was removed and these are not more on the disks?
The resources not only disappear on the list
produced by "drbdmanage a" but are not on disks
with "locate".
Robert, please let us better know,

I'm freaking out!.
In my previous message I sent the syslog about drbdmanaged startup at
boot time, hoping for help.
Moreover today, starting servers, not only I had to make drbdmanage
restart but after done it , checking drbdsetup status I found a
problem on vm-104:

Thanks, Rob,
I understand that you use PVE and DRBD only for testing and not in
production, right?

Hi all,
I've set a cluster of 3 servers with Proxmox 4.2 and DRBD9; Proxmox
on 2 RAID1 HDD and DBRBD9 on 4 RAID 10 HDD.
DRBD9 use a complete mesh network configuration, with 2 dedicated
Ethernet interfaces for each node, connected with cross patch (no
switch connections).
