  1. PBS PVE Fail Backup

    Hi, Don't see any followup to this - but we're having precisely the same problem. This is a brand new PBS installation - all updates are done - and the zpool layout is as follows: root@pbs-01:~# zpool status pool: PBS01-Datastore state: ONLINE scan: scrub repaired 0B in 00:17:24 with 0...
  2. Issue with OVS native VLAN tagging?

    Hi, We have an issue with OVS native VLAN tagging. For a subset of VMs - that should be natively tagged to VLAN 6 - we're unable to get the native VLAN tagging to work. When we hardset the network interface to VLAN6 for the affected VM, everything works fine, but for some reason, if we leave...
  3. Moving VM disks on hosts with no shared storage, but not using replication.

    Hi, To add to what Mira is saying.. You don't require shared storage in order to do either a live migrate or a migrate of shut-down VMs - the only difference is that with a live migrate you will be able to select the destination filesystem/dataset you would like the VM and its disks to be...
  4. NFS soft mount option in PVE Cluster Storage?

    Hi All, We have occasional issues across a 20-node cluster that has an NFS share configured as part of the cluster storage (i.e. in /etc/pve/storage.cfg). Basically every so often the NFS server becomes unresponsive - we use it for backups and not for running VMs - but this causes hosts to...
  5. VM IO drops to near 0

    Hi Aaron, I work with @Chaosekie so I'm adding my bit on this. The zpool status is from the PVE host - whilst your comments are valid, we don't have performance issues on the PVE hosts using RAIDZ2/3 pools - and data resilience is critical for us. We limit default VM disk IO to 80Mbytes / 5000...
  6. Updating Proxmox..

    Hi, We run a 20-node production cluster, with just over 1100 VMs. Hosts are typically Intel XEON Scalable processors, with between 768GB-1TB RAM, and between 1-2 RAIDZ3 SSD pools per host - with roughly 10TB usable per pool. We do not have separately installed OS pools i.e. the primary/first...
  7. Issue with intervlan comms between VMs on SAME host when firewall is enabled

    Hi, Any ideas on this? Nothing obvious we are missing? Kind regards, Angelo.
  8. Issue with intervlan comms between VMs on SAME host when firewall is enabled

    Hi, We're having a strange issue with inter-VLAN comms/networking between VMs on different VLANs on the same host. We have experienced the same issue on hosts setup with Linux OR OVS bridging - and because of the fact that we segment customer VMs into customer-specific VLANs, we manage VMs...
  9. VM CPU usage during backup

    Hi, We are busy having the same sorts of issues - to the point that a bunch of VM CPU loads hit 100% utilisation during backups (or close to that..) As regards the diagnostics on this, I get what @dietmar is saying about computing data checksums and compression, but surely this wouldn't...
  10. ZFS - error: no such device, error: unknown filesystem, Entering rescue mode

    Thnx Thomas, I can confirm the process works just fine.. :) Just a very small suggestion to add to the notes (it's not immediately obvious): you have to do an upgrade to 6.4 first before trying to run proxmox-boot-tool and make sure NOT to do a 'zpool upgrade' yet (last step). Stating the...
  11. ZFS - error: no such device, error: unknown filesystem, Entering rescue mode

    @fabian thanks for the info above. Just to confirm if my understanding is correct: 1. New 6.4 installations with ZFS will no longer have any issues with zpool upgrades and issues with GRUB on reboots - by default? 2. I'm assuming the howto on switching to this new boot mode will indicate...
  12. Baselining Proxmox Updates..

    Thanks @ness1602 Our issue is not updating each node :) - we just want to try and keep all hosts at the same update/'release' level. By the time we've migrated VMs between hosts to do updates (which can take a couple of weeks), we're already in a place where updates have been released in the...
  13. Baselining Proxmox Updates..

    Hi, We (currently) have a 15-node cluster and adding a number of additional nodes migrating from SmartOS. Each host has between 768GB-1.5TB RAM and either 1or 2 RAIDZ3 pools (with about 13TB of usable storage for each pool) - hosting between 50-100 VMs each, so we have fairly dense hosts...
  14. Proxmox Backup Server 1.0 (stable)

    Great news and congrats on the release :) We're excited to try this out.. Quick question - as regards datastore options: I'm assuming it's possible to attach NFS mounts, CephFS,RBD etc. as datastore options for PBS? Or must it only be local direct-attached storage? We'll start playing with...
  15. pmxcfs - dcdb failure

    Hi Oguz, Here you go: root@pve-11:~# ls -ali /var/lib/pve-cluster total 976 21984 drwxr-xr-x 3 root root 7 May 8 07:54 . 5 drwxr-xr-x 38 root root 38 May 7 10:49 .. 66979 drwxr-xr-x 2 root root 3 Apr 1 06:28 backup 66182 -rw------- 1 root root 962560 May 14...
