METHODS

ATTRIBUTES

The following is a list of filesystem properties which may be queried as methods through the parent Sys::Filesystem object.

account: Used by the dodisk command to determine the filesystems to be processed by the accounting system.
boot: Used by the mkfs command to initialize the boot block of a new filesystem.
check: Used by the fsck command to determine the default filesystems to be checked.
dev: Identifies, for local mounts, either the block special file where the filesystem resides or the file or directory to be mounted.
free: This value can be either true or false. (Obsolete and ignored).
mount: Used by the mount command to determine whether this file system should be mounted by default.
nodename: Used by the mount command to determine which node contains the remote filesystem.
size: Used by the mkfs command for reference and to build the file system.
type: Used to group related mounts.
vfs: Specifies the type of mount. For example, vfs=nfs specifies the virtual filesystem being mounted is an NFS filesystem.
vol: Used by the mkfs command when initializing the label on a new filesystem. The value is a volume or pack label using a maximum of 6 characters.
log: The LVName must be the full path name of the filesystem logging logical volume name to which log data is written as this file system is modified. This is only valid for journaled filesystems.
