gerard6110 Posted July 2, 2020 Share Posted July 2, 2020 Hi, After installing 6.9.0.beta22 and updating the VMs (as per SpaceInvader One video), I can no longer connect to my Windows 10 VMs (via remote desktop). With nVidia video passthrough, I have no VNC. Before updating the VMs I still could. The only change would be virtio to virtio-net. Manually changing it back to virtio did not help, obviously. So what else has changed? Also, when booting the VMs they run at 100% (all 6 cores assigned to it). Of course I could go back to 6.8.3 stable but wish to stay on this one. Any thoughts?

gerard6110 Posted July 2, 2020 Author Share Posted July 2, 2020 ... as a follow-up: Restored 6.8.3 and then no VMs at all, as Libvirt Service failed to start. Quote Link to comment
gerard6110 Posted July 2, 2020 Author Share Posted July 2, 2020 It appeared that after restore my system got destroyed! libvirt.img gone and a complete share AllDomains gone! Not amused. Quote Link to comment
gerard6110 Posted July 2, 2020 Author Share Posted July 2, 2020 ... and also Docker Service failed to start. Also here file and Share gone! Quote Link to comment
gerard6110 Posted July 2, 2020 Author Share Posted July 2, 2020 ... after further investigation it appeared that my complete nvme cache (with 2 nvme's) was gone; not mounted! Quote Link to comment
gerard6110 Posted July 2, 2020 Author Share Posted July 2, 2020 ... pfffew: restoring the flash drive put me back in business. So definitely: backing up flash before going to 6.9.xxx! Quote Link to comment

From the beta release notes: Quote Note: When you upgrade a server which has a cache pool defined, a backup of config/disk.cfg will be saved to config/disk.cfg.bak, and then cache device assignment settings are moved out of disk.cfg and into a new file, config/pools/cache.cfg. If later you revert back to a pre-6.9 Unraid OS release you will lose your cache device assignments and you will have to manually re-assign devices to cache. As long as you reassign the correct devices, data should remain intact. Quote Link to comment
gerard6110 Posted July 5, 2020 Author Share Posted July 5, 2020 (edited) To Johnnie: Thanks for the explanation. As going back to pre 6.9 is therefore quite an issue (because of the major system changes), my suggeston would be that upgrading to 6.9 would only be allowed after a backup of the flash drive; at least a big warning to be displayed, like "WARNING: If you have a cache pool, a flash backup is mandatory, because if going back to pre 6.9 after upgrading to 6.9 you WILL loose your cache pool and therefore possibly all your dockers and VMs (if you have setup your system following our advice; on the cache only)".
