10
12 The nilfs-resize program will resize NILFS2 file systems. It can be
13 used to enlarge or shrink a mounted file system located on device.
14 This feature is only available on the kernel supporting on-line resiz‐
15 ing. Resizing for unmounted file systems are not supported at present.
16
17 The size parameter specifies the requested new size of the filesystem.
18 The size of the filesystem may never be larger than the size of the
19 partition. Optionally, the size parameter may be suffixed by one of
20 the following units designators: ´s´, ´K´, ´M´, ´G´, or ´T´, for 512
21 byte sectors, kilobytes, megabytes, gigabytes, or terabytes, respec‐
22 tively. If size parameter is not specified, it will default to the
23 size of the partition.
24
25 This program does not manipulate the size of partitions. If you wish
26 to enlarge a filesystem, you must make sure you can expand the size of
27 the underlying partition first. This can be done using fdisk(8) by
28 deleting the partition and recreating it with a larger size or using
29 lvextend(8), if you are using the logical volume manager lvm(8)
30
31 If you wish to shrink a nilfs2 partition, first use nilfs-resize to
32 shrink the size of filesystem. Then you may use fdisk(8) to shrink the
33 size of the partition. When shrinking the size of the partition, make
34 sure you do not make it smaller than the new size of the nilfs2
35 filesystem.
36
37 This command is valid only for mounted NILFS2 file systems, and will
38 fail if the device has no active mounts.
