Chapter 2: mx Commands 57

The --persist argument causes the filesystem to be mounted

automatically whenever the server is rebooted. The --activate argument

mounts the filesystem now. The --path argument specifies the directory

mountpoint for the filesystem; this mountpoint must already exist.

<filesystem> is the label given to the filesystem when it was created.

The mount options are as follows:

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.

Unmount a filesystem:

mx fs unmount [--persistent] [--active] <filesystem>

<server> ...
