NAME

6       lscp - list NILFS2 checkpoints
7

SYNOPSIS

9       lscp [options] [device]
10

DESCRIPTION

12       lscp is a utility for displaying checkpoints or snapshots of the NILFS2
13       file system found in device.  When device is omitted,  /proc/mounts  is
14       examined to find a NILFS2 file system.
15
16       This  command  will fail if the device has no active mounts of a NILFS2
17       file system.

FIELD DESCRIPTION

49       Every line of the lscp output consists of the following seven fields:
50
51       CNO    Checkpoint number.
52
53       DATE   Creation date.
54
55       TIME   Creation time.
56
57       MODE   Mode  of the checkpoint; cp for a plain checkpoint, and ss for a
58              snapshot.
59
60       FLG    Flags on the checkpoint. At present, character ``i'' is  printed
61              in  the field if the checkpoint was created only by garbage col‐
62              lection, checkpoint mode change, or  other  change  of  internal
63              state.  Otherwise ``-'' is printed.
64
65       NBLKINC (optional)
66              Number of blocks appended by the checkpoint.  This field is dis‐
67              played instead of BLKCNT field when -g option is specified.
68
69       BLKCNT Number of blocks used by the checkpoint.
70
71       ICNT   Number of inodes included in the entire file system at the  time
72              specified by the checkpoint.
73

BUGS

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