    Proxmox Cluster from 5.1 to 5.4, eventually to 6.0

    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...

    Proxmox Cluster from 5.1 to 5.4, eventually to 6.0

    Thank you, do you think I may come across any issues when adding a node running pve 5.4 to a 5.1 cluster?

    Proxmox Cluster from 5.1 to 5.4, eventually to 6.0

    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...

    SSD / RAID question

    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...

    Slow vzdump backups to NFS

    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)...

    Node icon showing offline

    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...

    Node icon showing offline

    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...

    a VM to monitor traffic

    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.

    Proxmox with Synology iSCSI Performance

    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...

    HA Failover and resources

    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...

    Ceph and SSD's Questions

    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...
