Introducing Network File System Version 4 on HP-UX 11i v3

Figure 16. NFSv4 Cross Mount
Note that the NFSv2/NFSv3 clients will still need to mount the server’s file systems separately to
access the contents of both shared file systems.
Example of Cross Mounts
Figure 17 and Figure 18 illustrate the use of the Cross Mounts feature. The setup consists of:
• NFSv4 Server: hpnfs161
# share /a/b
# share /a/b/c/d
where /a/b and /a/b/c/d are two different file system partitions as shown in Figure 17.
• NFSv4 Client: hpnfs163
# mount –o vers=4 hpnfs161:/ /mnt
# cd /mnt/a/b; # ls
# cd /mnt/a/b/c/d; # ls
Figure 17 shows the server setup and the directory contents of the two shared file systems.
