Sure that shared network storage like ceph, glusterfs, etc. can have problems, but local storage can have them too! :P You should understand, that it takes time to copy data from one cluster members local storage to other. Fabian - two-phase short-downtime migration for containers is planed ir...

I would use local and shared storage combined in your case. Critical VM's run on shared storage and non critical on local dir.

Today happened again! Now i figured out that there was an urbackup process running on that mailserver. But still - why does VM just stopped? Host or VM had no resources to manage incremental backup, so it just killed this VM!? Syslog for host machine ar VM as empty as last time. Any ideas?

Hi! I have 6 server proxmox cluster, each server installed on ZFS mirror, that is used for VM storage. The problem is, that today one VM was just shut down with no evident reason. After starting this VM back up, checked syslog on vm and host machine! VM is a mailserver - last message before...

Sorry - a bit misunderstood :) Thanks a lot - will make a kernel upgrade tonight.

Hi there! We have the same issue on our server cluster. Fabian - is this bug fixed in pve-kernel-4.4.35-2-pve that is available using dist-upgrade or it is better to install the version you built? Thanks in advance!

Hi, there! Today had a strange situation with image restore: 1. Source server was Proxmox 3.1 (pretty old, i know), everyday backup snapshot is made on NFS. 2. Today had a plan to migrate one qemu VM to new 4.2 proxmox cluster. 3. Stopped VM (Ubuntu web server), tried to make a fresh backup...

Looks like problem with Seagate SATA disks. I found this: http://forum.proxmox.com/threads/7466-Disk-IO-errors-on-all-sata-disks-disks-dropped-out?p=45908#post45908 So i guess i will try to update my ST1000NM0011 (1TB) x6 firmware. If nothing changes - will switch to WD.

No luck :( Problem still actual! Any ideas?! Anyone?

Hi there! I have the same problem, but with QEMU and the thing is that this problem appears only to VM, that are bigger than 25GB during backup process. VM's are Ubuntu 12.04.2 LTS 64bit. Will try to disable this USB3 feature and write down if problem is gone! pveversion -v pve-manager: 2.3-13...

Figured it out yesterday by myself :) The problem was, that there was no closing tag</clusternode> after defining each node. It works now! Thanks a lot, adamb!!! :)

Ok, tested my settup with: fence_ipmilan -l User -p Passwd -P -a 10.10.10.6 -T 4 -o off -v Server goes down. With: fence_ipmilan -l User -p Passwd -P -a 10.10.10.6 -T 4 -o on -v Server comes alive :) My cluster.conf.new looks like this, but it doesnt go through validation :( <?xml...

It's the first time i'm trying to use SM interface. In BIOS configured BMC interfaces for all nodes. Each has their IP address, subnet mask, gateway, user and password. All nodes has a patch cord to switch, but there is no indication of any kind of activity on that interface. Ok, installed...

So i have to install ipmitool on all nodes?! But how to configure this SM interface to have an IP, username and passwd?! Sorry about those stupid questions, but i just want to get this thing working!

Thanks! I will try this out and ask an advice if needed! :)

Hi, there! Could you give a hint how to do that?! I have 3 IBM X3550 servers with Proxmox 2.3 configured in cluster, but i would like to enable HA as well using SM interface. Thanks in advance.
