19.2.6 crash daemon - aes256k not supported?
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: Sep 18 10:21:24 myhost bash[3327369]: INFO:ceph-crash:pinging cluster to exercise our key Sep 18 10:21:24 myhost bash[3327369]: 2026-09-18T08:21:24.374+0000 766f4adb1640 -1 monclient(hunting): handle_auth_bad_method server allowed_methods [2] and I support [1] Sep 18 10:21:24 myhost bash[3327369]: 2026-09-18T08:21:24.374+0000 766f4a5b0640 -1 monclient(hunting): handle_auth_bad_method server allowed_methods [2] and I support [1] Sep 18 10:21:24 myhost bash[3327369]: 2026-09-18T08:21:24.374+0000 766f49daf640 -1 monclient(hunting): handle_auth_bad_method server allowed_methods [2] and I support [1] Sep 18 10:21:24 myhost bash[3327369]: 2026-09-18T08:21:24.374+0000 766f4c83b640 -1 monclient: authenticate NOTE: no keyring found; disabled cephx authentication Sep 18 10:21:24 myhost bash[3327369]: [errno 13] RADOS permission denied (error connecting to the cluster) Sep 18 10:21:24 myhost bash[3327369]: INFO:ceph-crash:monitoring path /var/lib/ceph/crash, delay 600s
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.

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:
