question Anybody can answer The best answers are voted up and rise to the top getting input/output error from NFS client on RHEL5 up vote 1 down vote favorite I have two RHEL5 boxes on a private network together (192.168.2.0/24) and I am trying to export a file system from one to the other but I keep getting the following error: mount.nfs: Input/output ls: reading directory .: input/output error nfs error on the client side I see this output: mount: trying 192.168.2.101 prog 100003 vers 3 prot tcp port 2049 mount: trying 192.168.2.101 prog 100005 vers 3 prot tcp port 960 and on the server side I see this: Sep 20 14:14:32 omicron mountd[18739]: authenticated mount request from 192.168.2.87:635 for /srv/nfs/web (/srv/nfs/web) but that's all.

User ID and Group IDAn issue with the NFS server (JLAN-11) transposes the GID and UID of the NFS client user, meaning that Unix accounts that have a user-id that differs from the group-id will not gain authentication. The Alfresco-NFS server will deny them access. The user will only see ls: /mnt/alfresco: Input/output error. This mount.nfs input/output error issue lasted this long presumably because so many Linux distributions create a new group for each new user, unless told otherwise. Though the bug is declared closed, it has yet to filter down to SVN, and org.alfresco.filesys.server.auth.AlfrescoRpcAuthenticator.authenticateRpcClient(int, RpcPacket) still reads the GID before the UID. NFS server port number is not ephemeralIf the NFSServerPort property is not given, it defaults to 2049. This is likely to conflict with a native NFS server, if any. The portmapper daemon, when properly used, removes any dependency upon a well known port number, however neither Alfresco nor any native NFS server seem to use this functionality. Running native and Alfresco NFS servers on the same hostIf you wish to run the native server along side the Alfresco NFS server, you cannot depend upon the portmapper, as there is a 50 percent chance that it will retain the native NFS details. When using nfs-utils-1.0.10 version on Linux, mount.nfs will defer to the portmapper for the port-number, version-number, and protocol of the NFS server in question. Only if all three of these ar
