E2FSADM(8)

NAME
e2fsadm - ext2 Filesystem / LVM administration

SYNOPSIS
e2fsadm [-d/--debug] [-h/-?/--help] { -l/--extents [+/-]LogicalExtentsNumber | -L/--size [+/-]LogicalVolumeSize[kKmMgGtT]} [-n/--nofsck] [-v/--verbose] LogicalVolumePath

DESCRIPTION
e2fsadm allows resizing of a logical volume (see lvm(8), lvcreate(8)) containing an unmounted ext2 filesystem and then extending the filesystem by resize2fs(8) afterwards or reducing the filesystem first and then reducing the logical volume afterwards.

  OPTIONS

-d, --debug
    Enables additional debugging output (if compiled with DEBUG).

-h, -?, --help
    Print a usage message on standard output and exit successfully.

-l, --extents [+/-]LogicalExtentsNumber
    Resize the filesystem/logical volume to the number of logical extents relative (with +/-) to the old size or absolute without it.

-L, --size [+/-]LogicalVolumeSize[kKmMgGtT]
    Resize the filesystem/logical volume to the number of megabytes relative (with +/-) to the old size or absolute without it. A size suffix of k for kilobyte, m for megabyte, g for gigabyte or t for terabyte is optional.

-n, --nofsck
    Avoid the filesystem check before the resize operation. A filesystem check is mandatory before resize2fs(8). Usefull, if a check has been done before starting e2fsadm.

-t, --test
    Test run without real resizing.

-v, --verbose
    Gives verbose runtime information about e2fsadm's activities.

DIAGNOSTICS
e2fsadm uses e2fsck(8), lvextend(8), lvreduce(8) and resize2fs(8) internal. It returns an exit state of 0 for success or > 0 for error:
1  the filesystem size is invalid
2  the logical volume name is missing
3  the logical volume name is invalid
4  the logical volume doesn't exist
5  an error occured while reading the VGDA
6  an error occured while resizing the filesystem
7  /proc/mounts is not existing
8  the filesystem is mounted
9  the filesystem type is not ext2
10 the e2fsck(8) command is missong or was not found
11 resize2fs(8) is missing or was not found
12 unable to run e2fsck(8)
13 unbale to run resize2fs(8)
14 an error occured while reading logical volume
15 logical volume size error
16 lvextend(8) is missing or was not found
17 unable to run lvextend(8)
18 lvreduce(8) is missing or was not found
19 unable to run lvreduce(8)
95 driver/module not in kernel
96 invalid i/o protocol version
97 error locking logical volume manager
98 invalid lvmtab (run vgscan(8))
99 invalid command line

ENVIRONMENT VARIABLES

E2FSADM_RESIZE_CMD
    Command to call instead of resize2fs(8). Take a look at for eg. ext2resize(8).

E2FSADM_RESIZE_OPTS
    Options for the EXT2_RESIZE_CMD
