Filesystem mount options (HTFS, EAFS, AFS, S51K)

Filesystem mount options (HTFS, EAFS, AFS, S51K)

The Filesystem Manager supports the following mount options for non-root HTFS, EAFS, AFS, and S51K filesystems; for root filesystems, see ``Modifying HTFS, EAFS, AFS, and S51K root filesystem mount configuration''.

Mount as Temporary Filesystem
mounts the filesystem as a temporary data area (such as /tmp). This improves system performance because the system updates the information less frequently. (The potential for loss of data is increased as a result.)

transitions the filesystem to a clean (consistent) state at regular intervals. This reduces the probability that your filesystem will need cleaning if the system is halted unexpectedly.

performs ``intent logging'', recording filesystem transactions to a log file before they are committed to disk. This increases data availability by reducing the checking and repairing the filesystem to a few seconds. This time is independent of filesystem size.

These options apply to HTFS filesystems only:

Maximum number of file versions
determines maximum number of undeletable (versioned) files allowed on the filesystem. A value of 0 disables versioning.

Minimum time before a file is versioned
sets minimum time before a file is versioned. If set to 0, a file is always versioned (as long as Maxiumum number of file versions is greater than 0). If set to a value greater than 0, the file is versioned after it has existed for that number of seconds.
