    • RE: Why do I see this message?

      @olivierlambert

      I work with enterprise companies and they NEED those reminders to let them know they should be using the supported version. I don't really see them as annoying at all.

    • RE: XCP-ng 8.3 public alpha 🚀

      @olivierlambert

      This was a full backup not a delta so that makes sense. I think I need more of my lab servers to be on 8.3 so I can do some more testing. I did not find any issues and nothing broke using it so I need to try harder. 😉

    • RE: XCP-ng 8.3 public alpha 🚀

      I did some testing with the 8.3 and it all went smooth except for one thing. We did a backup of a VM on 8.3 and if we try and restore it to version 8.2 I get the error

      "IMPORT_INCOMPATIBLE_VERSION"
      

      which makes sense and it's just a lab system so nothing critical. Is there a way to bring it back to 8.2 or should I update the rest of my lab to 8.3? 🙂

    • Enable NBD Backups for a network

      I am running xo-server 5.109.0 & xo-web 5.111.0 and I have enabled NBD from the UI and verified that the parameter is showing on that network. This is the network on which XO is talking to XCP-NG .

      xe network-param-list uuid=12eaf1ae-9596-723e-a534-4d5a101ec4b4

                       purpose (SRW): nbd
      
      

      I know I also have to be using the multiple data blocks on for the backup repository but I do have a few other questions:

      • Because the NBD option is now in the XO UI do I still need to edit the XO config.toml file & restart XO to enable or is that automatic?
      • Are there any firewall changes on the XCP-NG host or does this work over 443?
      • Does it matter if XO is running in another pool?
      • In the Xen Orchestra 5.76 Blog Post it was mentioned the "Lock" in the new "NBD" row which I see but is there some change I need to make?

    • RE: Change default filter in VMs list from current "power_state:running"

      @bullerwins

      It's a wonderful feature, you can have customized filters for VM, storage, Templates, and Pools. Combine that with using lots of tags and it makes larger deployments very manageable.

    • RE: Forgot password for the webgui

      @isener

      I think the XO-CLI has to be registered with XO to get it working and seeing as you are locked out that is not an option. Maybe someone here will offer a way to edit the database if not I would just delete and rebuild XO.

    • RE: XCP / XO and Truenas Scale or Core

      @mauzilla
      Just an FYI, I have not tested the latest Scale 22.12 RC1 for performance but the previous versions of scale under some conditions was quite a bit slower. I have a video covering this topic here with the benchmarks and methodology used for testing.

    • RE: Delta Backups deleting .vhd files during merge operation

      @Gheppy

      The current version of TrueNAS-13.0-U3.1 has been stable for me, but this issue has persisted when doing Delta backups with SMB
      & TrueNAS, even older versions.
      https://xcp-ng.org/forum/topic/6148/delta-backup-showing-success-no-delta-saved

      My resolution to the issue was to move the backups over to NFS and they work well. Also, since I am using the newer "Store backup as multiple data blocks instead of a whole VHD file" option NFS is generally a bit faster with handling small files.

      I rebooted and I have tested both tcp:// and udp:// and it's not sending anything. Also checked using ss -t to and I don't see any TCP connection going to the logging server. Support # is 44423

    • XO logs to external syslog

      I really like this feature but I am having some issues getting it to work. I assume this goes in the config.toml file located in /opt/xo/xo-server for XO Community or /usr/local/lib/node_modules/xo-server for the XO Appliance.

      [log.transport.syslog]
      target = 'tcp://syslog.example.org:514'
      

      I have tested on both XO community and XOA and nether worked and I don't have any error messages in the log files stating the config is incorrect. I have rsyslog setup and working so I know it's able to reach and send to the log server and send data. Also, I assume this can this be done via UDP as well but changing the prefix to udp://?

    • RE: Change Management Interface VLAN`

      @kevdog

      Not really sure what your goal is, but for simplicity I recommend keeping the main interface on the native VLAN. If you are doing this for security, then you should use separate physical interfaces to keep the network segmented.

    • RE: Restoring Full Backup Error: Stream_vdi.Invalid_checksum

      I really think there is some bug in the TrueNAS Core SMB stack that I am fighting here because this issue
      https://xcp-ng.org/forum/topic/6148/delta-backup-showing-success-no-delta-saved?_=1666089968101
      I had reported before was only happening on TrueNAS Core via SMB. Also this is solved sine XO that extra integrity checking feature was added to the delta backups.

      No encryption on this remote. And if I have time before I leave I will test importing the XVA with CLI and see what error I get.

    • RE: Restoring Full Backup Error: Stream_vdi.Invalid_checksum

      I am going to be out of town until next week, but I can keep the backups so we can arrange a time to test it.

      I have done a few more tests, I setup a Synology using SMB and it backs up and restores just fine. I also moved the existing backups over to an NFS share and that previously created backup gives the same Stream_vdi.Invalid_checksum error with the same block number on restore.
