Error: statfs
/var/lib/ceph/9f4f9dba-72c7-11f0-8052-525400519d29/crash.podster1.mine.priv/keyring:
no such file or directory
and that is for all nodes.
But I find:
/var/lib/ceph/9f4f9dba-72c7-11f0-8052-525400519d29/crash/posted/
on all/each node - which path _was_ created by the cluster
(as opposed to human)
also, I find:
/var/lib/ceph/9f4f9dba-72c7-11f0-8052-525400519d29/crash.podster3/keyring
also on each node, which seems to contain other configs - as
'shell --name ...' above, was looking for.
No, failing mon I thought I should have mentioned it only as
trace of originating issue - but I did not think of causality.
Is this some hostnames / FQDN misconfiguration ? but if so,
then that was/is cluster/cephadm on its own.
OS resolver check /etc/hosts - DNS also involved later -
which contains:
-> $ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4
localhost4.localdomain4
::1 localhost localhost.localdomain localhost6
localhost6.localdomain6
10.1.1.61 podster1.mine.priv podster1
10.1.1.62 podster2.mine.priv podster2
10.1.1.63 podster3.mine.priv podster3
I added hosts to the cluster - and 'bootstraped' - with
their FQDNs.
thanks, L.
