Optimize file access for database data files.

Unmount a filesystem:

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

ALL_SERVERS|<server> ...

The --persistent argument removes the persistent status from the filesystem

mount. The --active argument unmounts the filesystem now.

Display status information:

mx fs status [--mounted|--unmounted] [--persistent]

[--verbose] [--standard|--snapshots]

The --mounted argument displays only mounted filesystems; --unmounted

displays only unmounted filesystems. The --persistent argument displays

only those filesystems with persistent mounts. The --verbose option

displays the FS type (always PSFS), the size of the filesystem in KB, and the

UUID of the parent disk. The --standard argument shows only standard

filesystems; the --snapshots argument shows only snapshots.

mx fs dump
