lockfs

- change or report file system locks

形式

/usr/sbin/lockfs [-adefhnuw] [-c string] [file-system]...

機能説明

lockfs is used to change and report the status of file system locks. lockfs reports the lock status and unlocks the file systems that were improperly left locked.

Using lockfs to lock a file system is discouraged because this requires extensive knowledge of SunOS internals to be used effectively and correctly.

When invoked with no arguments, lockfs lists the UFS file systems that are locked. If file-system is not specified, and -a is specified, lockfs is run on all mounted, UFS type file systems.

オプション

The options are mutually exclusive: wndheuf. If you do specify more than one of these options on a lockfs command line, the utility does not protest and invokes only the last option specified. In particular, you cannot specify a flush (-f) and a lock (for example, -w) on the same command line. However, all locking operations implicitly perform a flush, so the -f is superfluous when specifying a lock.

You must be super-user to use any of the following options, with the exception of -a, -f and -v.

The following options are supported.

-a

Apply command to all mounted, UFS type file systems. file-system is ignored when -a is specified.

-c string

Accept a string that is passed as the comment field. The -c only takes affect when the lock is being set using the -d, -h, -n, -u, or -w options.

-d

Delete-lock (dlock) the specified file-system. dlock suspends access that could remove directory entries.

-e

Error-lock (elock) the specified file-system. elock blocks all local access to the locked file system and returns EWOULDBLOCK on all remote access. File systems are elocked by UFS on detection of internal inconsistency. They may only be unlocked after successful repair by fsck, which is usually done automatically (see mount_ufs(1M)). elocked file systems can be unmounted.

-f

Force a synchronous flush of all data that is dirty at the time fsflush is run to its backing store for the named file system (or for all file systems.)

It is a more reliable method than using sync(1M) because it does not return until all possible data has been pushed. In the case of UFS filesystems with logging enabled, the log is also rolled before returning. Additional data can be modified by the time fsflush exits, so using one of the locking options is more likely to be of general use.

-h

Hard-lock (hlock) the specified file-system. hlock returns an error on every access to the locked file system, and cannot be unlocked. hlocked file systems can be unmounted.

-n

Name-lock (nlock) the specified file-system. nlock suspends accesses that could change or remove existing directories entries.

-u

Unlock (ulock) the specified file-system. ulock awakens suspended accesses.

-v

Enable verbose output.

-w

Write-lock (wlock) the specified file-system. wlock suspends writes that would modify the file system. Access times are not kept while a file system is write-locked.

オペランド

The following operands are supported.

file-system

A list of path names separated by whitespace. Note that file-system can be a directory rather than the specific name of a file system, such as / or /usr. For example, if you specify /export/home as an argument to a lockfs command and /export/home is mounted on the root (/) file system, the lockfs command will take effect on the root file system.

使用法

See largefile(5) for the description of the behavior of lockfs when encountering files greater than or equal to 2 Gbyte ( 231 bytes).

使用例

例 1 Using lockfs -a

In the following examples, filesystem is the pathname of the mounted-on directory (mount point). Locktype is one of “write,” “name,” “delete,” “hard,” or “unlock”. When enclosed in parenthesis, the lock is being set. Comment is a string set by the process that last issued a lock command.

The following example shows the lockfs output when only the -a option is specified.

example#  /usr/sbin/lockfs -a
Filesystem
Locktype
Comment
/
unlock
/var
unlock
example#

例 2 Using lockfs -w

The following example shows the lockfs output when the -w option is used to write lock the /var file system and the comment string is set using the -c option. The -a option is then specified on a separate command line.

example#  /usr/sbin/lockfs -w -c "lockfs: write lock example" /var
example#  /usr/sbin/lockfs -a
Filesystem
Locktype
Comment
/
unlock
/var
write
lockfs: write lock example
example#

例 3 Using lockfs -u

The following example shows the lockfs output when the -u option is used to unlock the /var file system and the comment string is set using the -c option.

example#  /usr/sbin/lockfs -uc "lockfs: unlock example" /var
example#  /usr/sbin/lockfs /var
Filesystem
Locktype
Comment
/var
unlock
