nilfs-utils version 2.2
umount.nilfs2 - unmount NILFS2 file systems
umount [-t nilfs2] [-dfilnrv] device | dir [...]
umount.nilfs2 [-nrv] dir [...]
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.|
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 <konishi.ryusuke> 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 https://nilfs.sourceforge.io.
