Checking if a connection to the GlusterFS TCP server port (6996 IIRC) is possible might be an indicator for working/failing - at least for setups that use TCP. I don't know if anything like that is possible for Infiniband-only setups. IIRC, Nagios can check if a port is open on a remote machine. That won't find something like disk/filesystem problems on the server, but it could report crashed GlusterFS server processes and machines that are not working at all. I know that this simple method won't provide a positive status (=it works) which would be preferable, but at least it can provide a negative status (=_something_ failed on _that_ machine) in some cases. @gluster.org: IIRC, some time ago someone requested a syslog feature to debug problems with GlusterFS as root filesystem for a diskless cluster - are there any news on that? Having the clients report problems to a central logging server might be useful for monitoring. Regards, Harald
