Hello,
Just thought I would give a little update to this as I hate leaving unsolved threads.
I took the advice above, one host at a time. I moved all VM's to a spare host, used the "apt update && apt dist-upgrade" commands to update the host from 5.1 to 5.4 which went smoothly. The cluster ran...
Hello.
I am looking to upgrade a production cluster of 8 nodes without restarting the virtual machines inside them, I do not use any form of Proxmox failover/fencing management and storage is NFS completely separate to the cluster. I read on the Proxmox docs that to get to 6.0, I first need to...
Hello,
I am running proxmox 3.4.13 and am having issues with two virtual machines hanging on vzdump. Storage is LVM over iSCSI

In my experience with consumer SSD's, I set the SSD's to JBOD on the hardware raid controller and software raid-1 SSD's as unless you have an expensive/new raid card you may have speed/support issues. Also I tend to leave 10-20% of the SSD free to allow for dead blocks as you wear out the SSD...
Hello
I am trying to backup virtual machines (LVM over iSCSi storage) in online mode but they are very slow. I have tested storage, network and cpu performance but can not work out what it is.
I have a dedicated machine with 22x 300GB SAS disks in raid 10 when I test with DD (if=/dev/zero)...
It is hard to say now as it healed itself some how but I do also like to leave an answer here if I do fix something as I hate it when people ask for help and then do not post how they solved. But earlier today:
I did run pvecm status and clustat and both were fine.
I did not test multicast...
Hello,
We recently added a 4th node to our cluster but had some issues due to us using our own wildcard certificate which I resolved by restoring the original cert on all nodes and then adding the node.
But the issue I am now having is that the icon is showing as offline on "queenie" and the...
We use ntop, installed on each proxmox node and then we use a NetFlow/sFlow collector.
We also use PRTG to monitor the uptime of all our nodes, storage and virtual machines using snmp protocol.
PRTG will send us SMS messages if a server goes down or using too much resources.
Hello and thank you for reading.
Currently we have a cluster/ha/fencing of 5 identical Proxmox nodes running roughly 20 virtual machines. Each node is an IBM x3650 M4 with 512Mb Cache and BBU with Raid 1 SAS drives (just for OS), bit overkill. We store all of our Virtual Machines on a Synology...
Re: Starting VMs on first node after second node failure on 2-node Proxmox cluster (D
Hello,
Seems like your logical volume is not activated.
Try this:
vgchange -a y vg0
Hello,
I have been running Proxmox for roughly two years now in production, know it quite well and working very well. We are currently putting together a new improved cluster of 5 nodes together with HA and fencing which is all up and running perfect in our office test rack.
Is there a way to...
Thanks Rob, I have not played with this yet but what if I had Proxmox installed in 2x SSD Raid1 and also used that for Journel or does the Journel need a dedicated disk?
EDIT: I think I have answered my own questions with this url for anyone else interested in reading...
