HP Clustered Gateway Device Management Software manual Mount options are

Chapter 2: mx Commands 69

The mount options are:

RW/RO

Mount the filesystem read-write or read-only. RW is the default.

ASYNC/ SYNC

ASYNC, the default, allows either asychronous or synchronous I/O to the filesystem. SYNC allows only synchronous I/O.

DEV/ NODEV

Interpret (or do not interpret) character or block special devices on the filesystem. DEV is the default.

EXEC/ NOEXEC

Permit (or do not permit) the execution of binaries on the mounted filesystem. EXEC is the default. NOEXEC can be used on a system that has filesystems containing binaries for other architectures.

SUID/ NOSUID

Allow (or do not allow) set-user-id bits and set-group-id bits to take effect. SUID is the default.

SHARED/ EXCLUSIVE

Either allow all servers having physical access to the filesystem to mount it or allow only one server. SHARED is the default.

ORDERED/ UNORDERED

With the ORDERED option, if a metadata operation will allocate user blocks, the user blocks are written to the filesystem before the metadata is written. With the UNORDERED option, the writes can occur in either order. ORDERED is the default.

CREATEDIR

Create the directory mount point.

localbrlocks

Disable cluster-coherent record locking. This mount option should be used with extreme caution. When cluster-coherent record lock operations are disabled, the record locks established against a file in the filesystem by each node in the cluster are invisible to all other nodes in the same cluster.

Before using this option, ensure that either all processes performing record lock operations in the affected filesystem are running on the same single node in the cluster, or that the necessary mutual exclusion
