NAME
umount.nilfs2 - unmount NILFS2 file systems
SYNOPSIS
umount [*-t nilfs2*] [*-dfilnrv*] device | dir […]
umount.nilfs2 [*-nrv*] dir […]
umount.nilfs2 [*-V*]
DESCRIPTION
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).
OPTIONS
See *umount*(8) for the full set of options. Commonly used options with NILFS2 are as follows:
- -V
- Print version and exit.
- -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.
AUTHOR
