umount.nilfs2 - unmount NILFS2 file systems
umount [-t nilfs2] [-dfilnrv] device | dir [...]
umount.nilfs2 [-nrv] dir [...]
umount.nilfs2 detaches the NILFS2 file system(s) mentioned from the
file hierarchy. This is the umount helper for NILFS2 to shutdown the
garbage collector nilfs_cleanerd(8) before detaching the file system.
Usually it should be invoked through umount(8).
See umount(8) for the full set of options. Commonly used options with
NILFS2 are as follows:
-i Don’t call umount.nilfs2. Valid for umount(8).
-n 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).
-r In case unmounting fails, try to remount read-only.
-v Verbose mode.
THE LOOP DEVICE
umount.nilfs2 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.
umount.nilfs2 is written by Ryusuke Konishi <firstname.lastname@example.org> for
NILFS2, based on the umount program included in the util-linux package.
umount.nilfs2 is part of the nilfs-utils package and is available from
nilfs(8), umount(8), mount.nilfs2(8), nilfs_cleanerd(8).
