    • RE: Backblaze as Remote error Unsupported header 'x-amz-checksum-mode' received for this API call.

      @florent said in Backblaze as Remote error Unsupported header 'x-amz-checksum-mode' received for this API call.:

      ,
      requestChecksumCalculation: "WHEN_REQUIRED",
      responseChecksumValidation: "WHEN_REQUIRED"

      I (previously as @jr-m4) just tried the patch you suggested. And I can confirm that this does indeed make the backup complete successfully!
      Great work finding a solution that quicklly!

    • RE: Keycloak : OIDC auth working but SAML fails with Internal Server Error or Invalid Requester

      @dsmteam
      Unfortunately this is the limit of what I know regarding SAML. The Google Workspace variant, was cobbled together after many hours of experimenting.

      I wish you the best of luck. And if you do find a solution, please consider adding to the docs as well. As this is an area where we desperately need more comprehensive docs (as you're experiencing).

      @dsmteam
      Make sure to enter a newline at the end of the certificate field.

      The SAML docs online are lacking. But I've written these instructions for Google Workspace SAML. Maybe this could help? And feel free to add to the docs if you happen to find a solution. 🙂

      @R2rho
      Faulty gear always sucks. But who would've guessed that two separate systems would produce the same problems. That is highly unlikely, but never impossible.

      Good luck with the RMA

      Given that BIOS and everything is updated to latest version possible.
      First thing I do then with these kinds of symptoms, is to disable all kinds of power management and/or C-states in BIOS.
      Some combinations of OS and hardware, just doesn't work properly.
      If for nothing else, it's a easy non-intrusive test to do.

      Update: I see that your motherboard has an IPMI interface. If the issues happen again, after you've disabled power management/c-states. You could use the remote functionality of the impi, to hopefully get some more info from the sensors and stuff.

    • [Docs] Which is it? Continuous Replication or Incremental Replication?

      XO and the docs are conflicting with each other, with what the backup function should actually be called. See attached pic for example.

    • [BUG]? If you don't have a disk attached, snapshots don't get cleaned up automatically

      This is truly a niche sittuation. But I noticed that when I have VMs without any disks attached. The Rolling Snapshot schedule doesn't remove snapshots in accordance to the schedules Snapshot retention.

      So I'm guessing that the schedule only looks at cleaning up snapshots of disks. But since the snapshots are acctually of the entire VM. Then maybe this should be takin into account as well?

      If this is working as intended, then just ignore this post 🙂

    • [Suggestion] Don't try to attach passthrough devices when doing Healthchecks

      I finally have some new hardware to play with. And I'm noticing that the Healtcheck fails, due to the vGPU being busy with the acctual host.

      INTERNAL_ERROR(xenopsd internal error: Cannot_add(0000:81:00.0, Xenctrlext.Unix_error(4, "16: Device or resource busy")))
      

      My suggestion is that for the sake of Healthchecks should unassign any attached PCIe devices. If it is crucial that they are attached, then maybe have an opt-in checkbox either in the VM or next to the Healthcheck portion of backups?

    • RE: Backup / Migration Performance

      @zach
      XCP-ng is unfortunately quite slow on individual streams for storage. It kind of disappears when using lots of VMs. But looking at any one individual one, it is surprising.

      A good read is the write up on Understanding the storage stack in XCP-ng

    • RE: Disater recovery backups crazy slow

      @ludovic78
      In the case of such a power outage, the backup would fail anyway.
      And I'm also assuming that you have a separate share/dataset for those specific backups.
      Coble it together with the Health Checks, and it is semi-production at least.
      If it is for such a highly critical environment, that it wouldn't tolerate more than that. Then obviously you should open a support ticket 🙂
