[pve-devel] [PATCH v1 master ceph 0/2] Fix Ceph Squid Module Loading

[Max R. Carrara]

Fix Ceph Squid Module Loading - v1
==================================

The first patch provides a workaround for the PyO3 ImportError that's
being thrown by the `restful` Ceph mgr Python module upon import.
This fixes the following error:

    2025-07-16T17:40:40.932+0200 7c315bc77080  1 mgr[py] Loading python module 'restful'

The second patch fixes how the Ceph mgr looks up the NOTIFY_TYPES
attribute of the mgr Python modules' classes. This also happens to fix
the `mgr_module` Python module import failure. In total, this fixes
errors like the following:

/var/log/ceph directory.
