lscp — list NILFS2 checkpoints

Synopsis

lscp [options] [device]

Description

lscp is a utility for displaying checkpoints or snapshots of the NILFS2 file system found in device.  When device is omitted, /proc/mounts is examined to find a NILFS2 file system.

This command will fail if the device has no active mounts of a NILFS2 file system.

Options

-a, --all

Do not hide minor checkpoints.

-b, --show-block-count

Show number of used blocks instead of appended blocks.  This is the default mode.

-g, --show-increment

Show number of appended blocks instead of used blocks.

-r, --reverse

Reverse order.

-s, --snapshot

List only snapshots.

-i index, --index=index

Skip index checkpoints (or snapshots) at start of input.

-n lines, --lines=lines

List only lines input checkpoints (or snapshots).

-h, --help

Display help message and exit.

-V, --version

Display version and exit.

Field Description

Every line of the lscp output consists of the following seven fields:

CNO

Checkpoint number.

DATE

Creation date.

TIME

Creation time.

MODE

Mode of the checkpoint; cp for a plain checkpoint, and ss for a snapshot.

FLG

Flags on the checkpoint. At present, character “i” is printed in the field if the checkpoint was created only by garbage collection, checkpoint mode change, or other change of internal state.  Otherwise “-” is printed.

NBLKINC (optional)

Number of blocks appended by the checkpoint.  This field is displayed instead of BLKCNT field when -g option is specified.

BLKCNT

Number of blocks used by the checkpoint.

ICNT

Number of inodes included in the entire file system at the time specified by the checkpoint.

Bugs

NILFS2 in Linux kernel version 2.6.38 and earlier does not support the block count (BLKCNT) information.
