Re: [Moosefs-users] Cannot write to mounted filesystem

[WK <wk...@bn...>]

Have you verified that you aren't firewalling out any MFS ports between 
the client/master/chunkservers?

Try with iptables turned off and see if you still see the issues.  
Absent that review your mount command.

Also check make sure selinux is not getting in the way.

-wk
