I'm having a lot of trouble with NFS going out to lunch between my RHEL7 machines. Users cannot access files, and get errors like: $ touch blah touch: cannot touch ‘blah’: Input/output error I'm attaching a pcap trace of the above touch during the problem. It seems that the server is returning NFS4ERR_EXPIRED. Reboots/restarts of nfs help for a bit but then the problems return. Other symptoms of trouble are messages like: RPC: fragment too large: 613351424 on the client. Any help with trying to track this down would be greatly appreciated. -- Orion Poplawski Manager of NWRA Technical Systems 720-772-5637 NWRA, Boulder/CoRA Office FAX: 303-415-9702 3380 Mitchell Lane orion@xxxxxxxx Boulder, CO 80301 https://www.nwra.com/
