Hi, we're running into an unexpected issue while using NFS... Maybe this could be added to FAQ... GlusterFS-server: 10.0.1.1, 10.0.1.2 Clients: 10.0.1.100, 10.0.1.101 Backupserver: 10.0.1.200 Access to the volume glustervol1 is permitted to the client adresses. glusterfs1-01 ~ # gluster volume info glustervol1 Volume Name: glustervol1 ... Options Reconfigured: nfs.disable: off nfs.rpc-auth-allow: 10.0.1.200 auth.allow: 10.0.1.100,10.0.1.101 Against expectations this did not work :( glusterfs1-01 ~ # showmount -e Export list for glusterfs1-01 Problem seems to be, that the IP-adresses of the GlusterFS-Servers are not in the auth.allow list. An "Authentication failed" can be seen in the logfiles of nfs.vol After executing gluster volume set glustervol1 set auth.allow 10.0.1.1,10.0.1.2, 10.0.1.100,10.0.1.101 everythings fine ;) glusterfs1-01 ~ # showmount -e Export list for glusterfs1-01: /glustervol1 10.0.1.200 Regards, Marcel
