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.
