Documentation updates and corrections 1–41
• If using the fsid capability in an NFS export entry, this fsid must be the same across all of the NFS

• HP SFS Version 2.2-1 supports a maximum of four NFS servers. Using more than four servers is not
supported at this time.
are replaced with the following:
• It is mandatory to specify the fsid parameter in the /etc/exports file.
Example: /mnt/lustre *(rw,no_root_squash,fsid=12345)
• An exported filesystem must have the same, unique, fsid value specified on each NFS server.
• The following caveat relates to POSIX file locking when using multiple NFS servers:
POSIX locking is supported among clients which mount a filesystem from the same NFS server.
Example: If NFS clients client1 and client2 import a filesystem from serv1, POSIX locking will
operate among those clients. If client3 and client4 mount from serv2 again, POSIX locking will
operate amount those two clients. However, if client4 were to request a wait lock which is held by
client1, the operating system will return EAGAIN. This limitation existed in previous releases but was
undocumented.
• HP SFS Version 2.3 has been tested with a maximum of four NFS servers. Using more than four
servers is not supported at this time.
