  1. Is there any way that iSCSI can offer snapshots & HA

    Hi Everyone, We've been struggling moving away from a mal-performing CEPH cluster at a customer site for a little while now, however, our NAS supports iSCSI and NFS, but not CEPH or ZFS over iSCSI. Is there truly no solution to include HA, Live Migration, and PBS Live Backups using an iSCSI...
  2. Upgrade from 7.0.10 Kernel 5.11.22-7 to 7.2.4 Kernel 5.15.35-1 Cannot Process Volume Group PVE

    Why Hello There! This evening I performed a regular upgrade to a client's long-standing (~2 years) hyperconverged PVE cluster. This cluster has some history but for the most part has been trouble free. The cluster is made up of homogeneous hardware, all Gen8 HPE Proliant servers with one node...
  3. Application Aware Processing for Linux and Windows database servers - Tmanok

    Hi Proxmox Team! Not sure if I asked a similar question recently, couldn't find it if I did but I know that this has been troubling me a lot lately. After working with Veeam long ago and recently supporting an organization that relies on it heavily, I was reminded that it offers Application...
  4. Specify storage for guest replication

    Hi PVE Team, I was reading the admin guide and revisited local guest replication with two hosts having local-zfs and a question came up. How would you specify a secondary storage. For example, if my node has local-zfs and another JBOD eSAS enclosure running attached-zfs or similar, how would...
  5. Proxmox Security Hardening Guidance?

    Hi Everyone, Does anyone know of official publications or resources regarding security hardening of Proxmox projects? PVE, PBS, PMG, client tools, etc... There seems to be a lack of documentation on the matter and I'm interested in seeing it pursued. I'm sure that a lot could be pulled from...
  6. Why don't VMs update certain hardware settings on reboot?

    Hi PVE Staff and Community, This has been a bane of mine for a while and I'm not sure if there is something I can do to "fix" it. Whenever I change a VM config (normally in the WebGUI) to provision a different number of resources, e.g. CPU cores, memory, etc, the VM only receives those...
  7. Windows Server Backup Shows 20+GiB dirty between backups within a couple hours!

    Hi Everyone, Something startling has occurred that I cannot seem to figure out. While reviewing backup logs, a specific Windows Server was backing up more data than expected, so I manually ran my backup task to PBS before today's nightly backup. After a successful backup of 170GiBs, I noticed...
  8. Plans to add Backup Storage Usage limit instead of retention numbers?

    Hi Everyone, Recently a thought crossed my mind while tuning a Proxmox Backup Server at one site and a Proxmox Virtual Environment server at another site: sometimes it is difficult to gauge the amount of disk space required while configuring backup retention. Some backup solutions, such as...
  9. [SOLVED] Renaming node ambiguity in documentation

    Hi Everyone, In the documentation https://pve.proxmox.com/wiki/Renaming_a_PVE_node there is a section that describes moving a node's /var/lib/rrdcached/db/pve2-node (and pve2-storage) sub-directory contents to the new hostname. However, I am unsure if it also needs rrdcached/db/pve#-* to be...
  10. Compression accelerator for PVE Backups

    Hey Everyone, PCIe accelerator cards of all shapes and sizes interest me, mostly because CPUs are these hulking beasts that handle significant amounts of processing and they are constantly taxed from "side" or "auxiliary" workloads outside of their primary tasks. Take a hypervisor, proxmox...
  11. Sharing Proxmox Helper Scripts

    Hey everyone, Found some nifty PVE setup scripts today on Reddit that I plan on utilizing very soon. https://tteck.github.io/Proxmox/ Have not tested these yet, however a few admins online used them with success and apparently it saved them quite a bit of time. Personally, I will use them...
  12. [SOLVED] Display Off-site PBS Host IPs

    Hey all, Simple question: Is there a way to see a local PBS instance [Public] IP from a remote? local (off-site) <-- Pulls from <-- remote (on-site) In short, I know the on-site (remote) PBS IP, but not the off-site (local) PBS IP. Checking /var/log/auth.log, /var/log/wtmp.log...
  13. [SOLVED] Understanding Garbage Collection with Remotes

    Hi Everyone, I am trying to understand garbage collection a bit better, I'll lay out two scenarios and ask you what happens so that I can better understand. PVE --> Backs up to --> Local PBS Remote PBS <-- Pulls from Local PBS 1. Garbage Collection on Local PBS: Keep last 10 Garbage...
  14. PVE GUI Reporting higher CPU usage than VM is reporting

    Hi Everyone, Running a standard Debian VM with a webserver and qemu-guest-agent, I'm wondering why PVE sees ~6-8% CPU usage when the VM is idle and the VM itself internally sees 0.1-1.8% while idle. Here are two screenshots showing PVE GUI and VM Top or htop at the same time to better...
  15. [SOLVED] Reconnect Proxmox Backup Server to PVE Cluster

    Hi Everyone, My local Proxmox Backup Server stopped networking for some reason (possibly a driver issue?) while running as a VM under BHyve, so I issued a systemctl restart networking and things returned to normal. However, the Proxmox Virtual Environment cluster now shows the PBS repository as...
  16. Log rotation failed - should I be concerned?

    Good morning! My newly updated PBS 1.1-13 system encountered an error last night regarding log rotation. The root disk is 64GB with not much used, and I don't see any obvious issues. () 2021-10-07T00:00:00-07:00: starting task log rotation 2021-10-07T00:00:00-07:00: task log archive was not...
  17. [SOLVED] Console welcome banner incorrect IP

    HI everyone, This could easily affect more than PBS (e.g. PVE) without me having seen this behaviour before, but PBS 2.0-10 welcome banner on console is stating the old/original IP that it was installed with. After moving it to a new physical location on a different network, on a different...
  18. Sync Task Status Error

    Hi everyone, Every time that I issue a sync job and wish to view the task window, the log is blank and the status tab shows the attached error (Bad Request (400) parameter verification errors parameter 'upid': value may only be 128 characters long). After the sync job is done, and I got to...
  19. Limit number of backups sent to remote (off-site) backup server

    Hi Everyone, Perhaps I've missed something in the forum or in the manual, but is there a way to reduce or limit the number of backups sent to a remote PBS? For example, say my on-site backup server had 8TiB and was used for A LOT of backups, but my off-site was say 4TiB usable, could the sync...
  20. LXC Backups getting stuck

    This has been an issue on a specific cluster of mine for quite some time and I'm still not sure why even after many updates, my LXC containers never backup (creating a backlog of backup tasks). A scheduled backup, suspend or snapshot, to an NFS drive, will stall before it even begins while it...
