Hi, I am seeing this error after an offline was deleted and while adding the host again. Thereafter, I have removed the /var/lib/cep folder and removed the ceph quincy image in the offline host. What is the cause of this issue and the solution. root@fl31ca104ja0201:/home/general# cephadm shell Inferring fsid d0a3b6e0-d2c3-11ed-be05-a7a3a1d7a87e Using recent ceph image quay.io/ceph/ceph@sha256:af79fedafc42237b7612fe2d18a9c64ca62a0b38ab362e614ad671efa4a0547e<mailto:quay.io/ceph/ceph@sha256:af79fedafc42237b7612fe2d18a9c64ca62a0b38ab362e614ad671efa4a0547e> root@fl31ca104ja0201:/# root@fl31ca104ja0201:/# ceph orch host rm fl31ca104ja0302 --offline --force Removed offline host 'fl31ca104ja0302' root@fl31ca104ja0201:/# ceph -s cluster: id: d0a3b6e0-d2c3-11ed-be05-a7a3a1d7a87e health: HEALTH_OK services: mon: 3 daemons, quorum fl31ca104ja0201,fl31ca104ja0202,fl31ca104ja0203 (age 28h) mgr: fl31ca104ja0203(active, since 6d), standbys: fl31ca104ja0202, fl31ca104ja0201 mds: 1/1 daemons up, 2 standby osd: 33 osds: 33 up (since 28h), 33 in (since 28h) rgw: 3 daemons active (3 hosts, 1 zones) data: volumes: 1/1 healthy pools: 24 pools, 737 pgs objects: 613.56k objects, 1.9 TiB usage: 2.9 TiB used, 228 TiB / 231 TiB avail pgs: 737 active+clean io: client: 161 MiB/s rd, 75 op/s rd, 0 op/s wr root@fl31ca104ja0201:/# ceph orch host add fl31ca104ja0302 10.45.219.5 Error EINVAL: Traceback (most recent call last): File "/usr/share/ceph/mgr/mgr_module.py", line 1756, in _handle_command return self.handle_command(inbuf, cmd) File "/usr/share/ceph/mgr/orchestrator/_interface.py", line 171, in handle_command return dispatch[cmd['prefix']].call(self, cmd, inbuf) File "/usr/share/ceph/mgr/mgr_module.py", line 462, in call return self.func(mgr, **kwargs) File "/usr/share/ceph/mgr/orchestrator/_interface.py", line 107, in <lambda> wrapper_copy = lambda *l_args, **l_kwargs: wrapper(*l_args, **l_kwargs) # noqa: E731 File "/usr/share/ceph/mgr/orchestrator/_interface.py", line 96, in wrapper return func(*args, **kwargs) File "/usr/share/ceph/mgr/orchestrator/module.py", line 356, in _add_host return self._apply_misc([s], False, Format.plain) File "/usr/share/ceph/mgr/orchestrator/module.py", line 1092, in _apply_misc raise_if_exception(completion) File "/usr/share/ceph/mgr/orchestrator/_interface.py", line 225, in raise_if_exception e = pickle.loads(c.serialized_exception) TypeError: __init__() missing 2 required positional arguments: 'hostname' and 'addr' Thank you, Anantha _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
