  1. Storage types for HA and live migration

    well my initial plan was to use SLURM sitting on top of Proxmox for job submission/management so I may be able to use that in some way by defining different compute node pools confined to different physical servers
  2. Storage types for HA and live migration

    When you put it like that it makes perfect sense!!! Is there any software you know of that could run on top of VMs to duplicate a program running on a VM on one physical node to a VM on on another physical node so if one goes down there is redundancy. I have a feeling this is some kind of...
  3. [TUTORIAL] Create a Proxmox 6.2 cluster GlusterFS storage

    See references [1] and [2] Do the following on all nodes unless stated. (a) Prepare disks (Assumes the disk is /dev/sdd) fsidk -l /dev/sdd pvcreate /dev/sdd vgcreate vg_proxmox /dev/sdd lvcreate --name lv_proxmox -l 100%vg vg_proxmox mkfs -t xfs -f -i size=512 -n size=8192 -L PROXMOX...
  4. Storage types for HA and live migration

    I created a GlusterFS cluster across 3 nodes successfully, create a VM on one node and used the GlusterFS for storage. I set the VM as HA with 1 migrate/boot. I simulated a node failure (turn off / not shutdown). The VM migrates to another node but restarts rather than continues so all CPU/RAM...
  5. Pseudo HA using VM Replication in Proxmox

    Not exactly. I have configured a 5 node PVE cluster with VMs accessible via NAT. I created ZFS storage on each PVE node (using some of the hdisks) for VM disks. I then set up VM replication from node 1 to 2, 2 to 3 ... 5 to 1 every 10 mins and using HA could get VMs to migrate and (re-)start...
  6. Storage types for HA and live migration

    Thanks. I am very impressed with Proxmox so far. If we end up using it for production I would really like my organisation to get at least a basic subscription to support the great work you guys are doing! Thanks for now.
  7. Storage types for HA and live migration

    Thank you. I'll give that a try. Are there any other storage options (https://pve.proxmox.com/wiki/Storage) which could be used for " (virtual) hyper-converged"?
  8. Storage types for HA and live migration

    I have configured a 5 node PVE cluster with VMs accessible via NAT. I created ZFS storage on each PVE node (using some of the hdisks) for VM disks. I then set up VM replication from node 1 to 2, 2 to 3 ... 5 to 1 every 10 mins and using HA could get VMs to migrate and (re-)start automatically...
  9. Cluster: Host node ZFS redundancy with additional (storage) replication for VMs /CTs - best practice?

    Thanks for your answer. One of the disadvantages of RAIDZ for me is that you cannot extended the RAIDZ (number of drives used) on a node but with a zfspool across the physical cluster nodes (with storage replication) I think I can just add more physical disks to any node and the zfspool at any...
  10. VM / VM template local-lvm: Which disk is it using?

    Rebooting the server seemed to clear it. Now usage says: No
  11. VM / VM template local-lvm: Which disk is it using?

    I've tried: fdisk /dev/sdc d (delete partition) Select partition number (REPEAT) w (write changes) q (quit) and: vgreduce pve /dev/sdc but get message: Failed to find physical volume "/dev/sdc"
  12. VM / VM template local-lvm: Which disk is it using?

    OK I think I figured out that everything (i.e. all the VM and VM template storage) is on the SSD (sda) by running: # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 223.6G 0 disk ├─sda1...
  13. VM / VM template local-lvm: Which disk is it using?

    I have created some VMs and VM templates on a PVE node for testing. The node has a SSD and 4 SAS drives. I installed PVE on the SSD drive and assumed when i selected local-lvm as the VM disks the VMs would all use the SSD for storage too. When I look under Node > Disks now I see that the usage...
  14. Cluster: Host node ZFS redundancy with additional (storage) replication for VMs /CTs - best practice?

    I am looking at the option of configuring a PVE cluster with storage replication (using a ZFS pool across the cluster nodes) so VMs and CTs can be moved to another node if the original host node has a failure. This is probably a PVE independent question but: when I create the initial ZFS...
  15. [TUTORIAL] PVE 6.2 Private VM (NAT) network configuration setup

    I had been trying to create a private IP (NAT) setup for my VMs and managed to do it as follows, heavily relying on infomation in reference [1]. I have re-titled this as a Tutorial now: 1. In the Proxmox web interface for the host network configuration create a second bridge: vmbr1 with IP...
