All OSD´s and Monitors are up from what I can see.
I read through the troubleshooting like mentioned in the ceph documentation for PGs and came to the conclusion that nothing there would help me, so I didn´t try anything - except restarting / rebooting OSD´s and Monitors.
How do I recover from this, it looks to me that the data itself should be safe for now, but why is it not restoring?
I guess the problem may be the crushmap.
Here are some outputs:

This is the crushmap I created and intended to use and thought I used for the past 2 months:
- pvestorage1-ssd and pvestorage1-platter are the same hosts, it seems like this is not possible but I never noticed
- likewise with pvestorage2
