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.
