NAME¶
Sys::Filesystem::Linux - Return Linux filesystem information to Sys::Filesystem
SYNOPSIS¶
See Sys::Filesystem.
INHERITANCE¶
Sys::Filesystem::Linux
ISA Sys::Filesystem::Unix
ISA UNIVERSAL
METHODS¶
- version ()
- Return the version of the (sub)module.
ATTRIBUTES¶
The following is a list of filesystem properties which may be queried as methods
through the parent Sys::Filesystem object.
- fs_spec
- Describes the block special device or remote filesystem to be mounted.
For ordinary mounts it will hold (a link to) a block special device node (as
created by mknod(8)) for the device to be mounted, like
'/dev/cdrom' or '/dev/sdb7'. For NFS mounts one will have
<host>:<dir>, e.g., 'knuth.aeb.nl:/'. For procfs, use 'proc'.
Instead of giving the device explicitly, one may indicate the (ext2 or xfs)
filesystem that is to be mounted by its UUID or volume label (cf.
e2label(8) or xfs_admin(8)), writing LABEL=<label> or
UUID=<uuid>, e.g., 'LABEL=Boot' or
'UUID=3e6be9de-8139-11d1-9106-a43f08d823a6'. This will make the system
more robust: adding or removing a SCSI disk changes the disk device name
but not the filesystem volume label.
- fs_file
- Describes the mount point for the filesystem. For swap partitions, this
field should be specified as 'none'. If the name of the mount point
contains spaces these can be escaped as '\040'.
- fs_vfstype
- Dscribes the type of the filesystem. Linux supports lots of filesystem
types, such as adfs, affs, autofs, coda, coherent, cramfs, devpts, efs,
ext2, ext3, hfs, hpfs, iso9660, jfs, minix, msdos, ncpfs, nfs, ntfs, proc,
qnx4, reiserfs, romfs, smbfs, sysv, tmpfs, udf, ufs, umsdos, vfat, xenix,
xfs, and possibly others. For more details, see mount(8). For the
filesystems currently supported by the running kernel, see
/proc/filesystems. An entry swap denotes a file or partition to be used
for swapping, cf. swapon(8). An entry ignore causes the line to be
ignored. This is useful to show disk partitions which are currently
unused.
- fs_mntops
- Describes the mount options associated with the filesystem.
It is formatted as a comma separated list of options. It contains at least
the type of mount plus any additional options appropriate to the
filesystem type. For documentation on the available options for non- nfs
file systems, see mount(8). For documentation on all nfs-specific
options have a look at nfs(5). Common for all types of file system
are the options 'noauto' (do not mount when 'mount -a' is given, e.g., at
boot time), 'user' (allow a user to mount), and 'owner' (allow device
owner to mount), and '_netdev' (device requires network to be available).
The 'owner' and '_netdev' options are Linux-specific. For more details,
see mount(8).
- fs_freq
- Used for these filesystems by the dump(8) command to determine
which filesystems need to be dumped. If the fifth field is not present, a
value of zero is returned and dump will assume that the filesystem does
not need to be dumped.
- fs_passno
- Used by the fsck(8) program to determine the order in which
filesystem checks are done at reboot time. The root filesystem should be
specified with a fs_passno of 1, and other filesystems should have a
fs_passno of 2. Filesystems within a drive will be checked sequentially,
but filesystems on different drives will be checked at the same time to
utilize parallelism available in the hardware. If the sixth field is not
present or zero, a value of zero is returned and fsck will assume that the
filesystem does not need to be checked.
