Hi all,
finally my (test) cluster is up and running!
Thank you very much for all the people here in list that helped me.
I now have some final questions:
1. In my cluster I have three monitors; when one monitor is down (I
simply shut down) raising a ceph -s underline that there are two
monitors alive and one down; when 2/3 of monitors down the cluster
became unresponsive (ceph -s remains stuck); is this normal?
2. In the ceph website I've read to install one manager for each
monitor; however I've found instructions to install just the first
manager on first monitor; can I follow the same procedure to install the
additional managers or a different procedure (like the one followed for
the additional monitors) is required?
3. Running CentOS I disabled firewalld and selinux; considering the
production cluster behind a perimeter firewall and not queried directed
by clients but through an API, your ideas about this choice is welcome;
4. Any experience to share about running ceph on debian instead of
centos / rhel is also welcome.
I point to share my work and any opinion will be appreciated.
Francesco
