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
- Dscribes 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/cdromaXX or aXX/dev/sdb7aXX. For NFS mounts one will have
<host>:<dir>, e.g., aXXknuth.aeb.nl:/aXX. For procfs, use
aXXprocaXX.
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., aXXLABEL=BootaXX or
aXXUUID=3e6be9de-8139-11d1-9106-a43f08d823a6aXX. 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 asaXXnone. If the name of the
mount point contains spaces these can be escaped asaXX\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 aXXaXXnoautoaXXaXX (do not mount when 'mount -a' is given,
e.g., at boot time), aXXaXXuseraXXaXX (allow a user to mount), and
aXXaXXowneraXXaXX (allow device owner to mount), and aXXaXX_netdevaXXaXX
(device requires network to be available). The aXXaXXowneraXXaXX and
aXXaXX_netdevaXXaXX 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.
