Just a feeling but I'd say that the imbalance in OSDs (one host having many more disks than the
rest) is your problem.

Assuming that your configuration keeps 3 copies of each VM image then the imbalance probably means
that 2 of these 3 copies reside on pve-3111 and if this host is unavailable, all VM images with 2
copies on that host become unresponsive, too.

Check your failure domain for Ceph and possibly change it from OSD to host. This should prevent that
one host holds multiple copies of a VM image.


Regards,

	Uwe
