@marcoi I don't have enough context to reply. You should open a new thread to discuss it, with details about your needs (always better to explain the needs before the technical solution).
Apologies for the late response - life got in the way!
I tried your tweaks and these appear to have solved the issue. The VM has been stable for over a month, which also included a reboot or two to install updates. Thanks for the help.
Dear all,
I needed to do a complete new installation of xcp-ng 8.3 LTS. I have backups of all VMs incl. the pool metadata. The latest daily backup was done on 09th of December and now, if upgrade the fresh installed xcp-ng to v35 release, the metadata backup can't be restored. Either by XenOrchestra or with "xe pool-restore-metadata" the restore is possible, always same error: "failed: restore incompatible version".
Any ideas what I'm doing wrong?
