SYNOPSISumount [-t nilfs2] [-dfilnrv] device | dir [...]
umount.nilfs2 [-nrv] dir [...]
DESCRIPTIONumount.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).
OPTIONSSee 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.
- Verbose mode.
