--- Begin Message ---Package: nfs-common Version: 1:1.2.2-4squeeze2 Tags: patch Assume the following: An NFS server supports only NFS version <4. This server is unreachable at a certain time. A Debian client boots and tries to mount a directory on the server with the 'bg' option, but without the 'nfsvers' option. Later, the NFS server comes up. Result: The client does _not_ mount the directory and the background mount is silently terminated. This typically breaks cross-mounted server scenarios. [Note that specifying 'nfsvers=3' is NOT a workaround, because then failing to connect the portmapper already terminates the mount.nfs process and no backgrounding happens at all. This is a separate bug IMHO.] Analysis: When first trying an NFSv4 mount, 'vers=4' is appended to the extra_options string in the mount options. Then, the next (background) attempt also happens with vers=4 and consequently, nfs_try_mount_v3v2() is never called. The mount fails, even though the V3 server would now be reachable. Fix appended. It looks like this bug is also present in current Debian nfs-utils git.
