This statement triggers alarm bells because a fresh install for an RPI using the RaspberryPI Foundation RaspiOS (64bit image highly recommended!) and then running the well documented scripted installation approach should not require more than 30 mins.
Did you add other applications too?
My installation was a new installation already. Therefor don't want to do it all over again. Going to do a new setup with a new pi soon. Hopefully it will be resolved on the new installation. For not it's not limiting me, as everything still works.
Yeah, added some app using docker and OMV CMS.
