NAME

umount.nilfs2 - unmount NILFS2 file systems  

SYNOPSIS

umount [-t nilfs2] [-dfilnrv] device | dir [...]

umount.nilfs2 [-nrv] dir [...]  

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:
-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

umount.nilfs2 is written by Ryusuke Konishi <ryusuke@osrg.net> for NILFS2, based on the umount program included in the util-linux package.  

AVAILABILITY
