[Nfs-ganesha-devel] Re: Recovery backend always gives timeout even though cluster is healthy

Hi,
I was trying to test out the new recovery backend, rados_kv. I am using nfs-ganesha
v2.7-dev13 with latest ceph master. I am testing using vstart cluster. But everytime I get
timeout "Failed to connect to cluster: -110". The cluster is healthy. I can also
give commands using the rados cli. Any pointers on what could be failing here?
Also, while working on this, I realized the default timeout (client_mount_timeout) is 300
in seconds, and there are 10 tries. So, in worst case timeout occurs after 50 mins. The
option, "client_mount_timeout" can be set in ceph.conf, but it seems like its
also possible to set in the ganesha config and pass it in function rados_conf_set(). [1]
Will it be useful to have such option in ganesha.conf?

It sounds like you have a communications issue, or perhaps your ganesha isn't using
the correct ceph.conf. I'd sniff traffic to see what it's doing, or look at lsof
output to see what sockets it's trying to open.
