umount.nilfs2 - unmount NILFS2 file systems
[-nrv] dir [...]
detaches the NILFS2 file system(s) mentioned from the file hierarchy.
This is the umount helper for NILFS2 to shutdown the garbage collector
(8) before detaching the file system. Usually it
should be invoked through umount
(8) for the full set of options. Commonly used options
with NILFS2 are as follows:
Print version and exit.
Don't call umount.nilfs2. Valid for umount(8).
Unmount without writing in /etc/mtab. This option must be used
carefully because mount.nilfs2 and umount.nilfs2 use the
table to store the process ID of nilfs_cleanerd(8).
In case unmounting fails, try to remount read-only.
THE LOOP DEVICE
will free the loop device (if any) associated with the mount, in case
it finds the option `loop=...' in /etc/mtab
. The -d option,
which also allows umount
(8) to free the loop device without the
`loop=...' option, is not supported.
