I don't think this has to do with aes256k but the known issue with crash. The same messages appear in 19.2.5 (freshly bootstrapped): ---snip--- Sep 21 12:10:58 tentacle-ubuntu24 systemd[1]: Started ceph-658bbff8-b5b4-11f1-9d89-fa163edcc19e@crash.tentacle-ubuntu24.service - Ceph crash.tentacle-ubuntu24 for 658bbff8-b5b4-11f1-9d89-fa163edcc19e.

I'm also not sure if it's supposed to be fixed in the latest Squid and Tentacle releases. Zitat von Andreas Eriksson <ceph-users@ceph.io>:
Hi,
When finishing up an upgrade to 19.2.6 I rotated keys for the crash daemon.
# ceph auth rotate --key-type=aes256k client.crash.$myhost # ceph orch reconfig crash.$myhost # ceph orch daemon restart crash.$myhost
But it seems it's not supported. I get this in the daemon logs:
