Dear all, I currently running the 3.1.2qa2 version on glusterFS and I'm still unable to mount GlusterFS directory on Solaris, AIX and HP-UX client contrary to Linux clients who work well. There is no other nfs server running on my glusterFS server and client, rpcbind is started, "showmount -e" on servers show correct output AND it's working fine on linux client. I'm using the command bellow : Solaris 10 cmd : mount -o proto=tcp,vers=3 nfs://ylal3020:38467:/athena /users/glusterfs_mnt error : command work but when I'm trying to access a file from the mount point (cat,tar...) I got " Input/output error" AIX cmd : mount -o proto=tcp,port=38467 ylal3020:/athena /users/glusterfs_mnt error : command work but when I'm trying to access a file from the mount point (cat,tar...) I got " Input/output error" HP-UX 11.11 cmd : mount -F nfs -o proto=tcp,port=38467 ylal3020:/athena /users/glusterfs_mnt error : nfs mount: get_fh: ylal3020:: RPC: Program not registered nfs mount: get_fh: ylal3020:: RPC: Program not registered nfs mount: retry: retrying(1) for: /users/glusterfs_mnt after 5 seconds => strange because rpcbind is up. Does someone have the same issue ? Thx for your help.
