NAME

nilfs-tune - adjust tunable file system parameters on NILFS file system  

SYNOPSIS

nilfs-tune [options] device  

DESCRIPTION

nilfs-tune is a utility to modify tunable file system parameters on NILFS2 file system in device.

This command is valid for inactive NILFS2 file systems. Modifying active mounts may cause severe damage.  

OPTIONS

-f
Force to modify even the specified file system is mounted.
-i interval
Set the commit interval of segment.
-m block-max
Set the threshold of the data amount of the segment construction.
-l
List the contents of the file system superblock, including the current values of the parameters that can be set via this program.
-L volume-label
Set the volume label of the file system. NILFS2 file system labels can be at most 80 bytes long. If volume-label is longer than 80 bytes, nilfs-tune will truncate it. The volume label can be used mount(8) and /etc/fstab(5) (and possibly others) by specifying LABEL=volume-label instead of a block special device name like /dev/sda5.
-U UUID
Set the universally unique identifier (UUID) of the file system to UUID. The format of the UUID is a series of hex digits separated by hyphens, like this: "c1b9d5a2-f162-11cf-9ece-0020afc76f16".
-h
Display help message and exit.
