Re: [MooseFS-Users] why master can't server any request at every o'clock?

[Aleksander W. <ale...@mo...>]

Hi,

Thank you for this information.
All results look reasonable.
Also I would like to add that you don't have problems with fork
operation. Metadata dump process took: 24.561 seconds:

Feb 29 10:00:24 mfs-CNC-GZSX-231 mfsmaster20936: store process has
finished - store time: 24.561

The most alarming aspect in your system log is that all chunkservers
disconnected at the same time and 34 seconds after metadata save:

Would you be so kind and send us logs from one chunkserver and client
machines.

We suspect that something is going on in your network.
It's look like your master server loosing network connection.

Please check your network configuration.
We are waiting for your feedback.
