RomRedel Posted March 11, 2022 Share Posted March 11, 2022 Hi, I just updated my unraid server to the version 6.10.0-rc3. Since then my /var/log is getting 100% full by one minute after boot.

JorgeB Posted May 19, 2022 Share Posted May 19, 2022 If not needed disabling IOMMU should get rid of that, BIOS update might also help. Quote Link to comment

Physical access to the machine is a bit difficult (no VGA monitor etc) so I can't really disable IOMMU in the BIOS. I've followed the instructions here and set it to `iommu=off` instead of `pt`, as I don't think I need it. I do have a GPU for Plex transcoding, but it's in a docker and not a VM. Parity check is running now so I can't reboot immediately, but I'll report back once it's done. Double thanks for your help -- yesterday your guide here saved me when the cache wouldn't mount. 1 Quote Link to comment
DrVenabili Posted May 19, 2022 Share Posted May 19, 2022 Update: unfortunately it didn't boot with iommu=off. Since I couldn't get the WebUI up there was no easy way of changing it back or trying iommu=pt, so I ended up restoring from a 6.9.2 flash backup from yesterday. Too bad for the built-in wireguard support, but I guess I'll stay on 6.9.2 for a while. Thank you again for your help JorgeB. Quote Link to comment
