E2FSADM(8)			     System Manager's Manual			       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]  [--version]  LogicalVol-
       umePath

DESCRIPTION
       e2fsadm	allows	resizing  of  a  logical  volume  containing  a mounted or unmounted ext2
       filesystem.  For unmounted filesystems it can extend  the  logical  volume  and	grow  the
       filesystem  using  resize2fs(8) or ext2resize(8), or shrink the filesystem and then reduce
       the logical volume afterwards.  For mounted filesystems it can extend the  logical  volume
       and grow the filesystem using ext2online(8).

   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 or by the number of logical extents.  If
	      you use + or - then the number will be relative the th current size of the  logical
	      volume, otherwise the volume will be resized to LogicalExtentsNumber extents.

       -L, --size [+|-]LogicalVolumeSize[kKmMgGtT]
	      Resize  the  filesystem/logical  volume to or by the given size.	If you use + or -
	      then the number will be relative the the current size of the logical volume, other-
	      wise the volume will be resized to LogicalVolumeSize.  A size suffix of K for kilo-
	      bytes, M for megabytes, G for gigabytes or T for terabytes can be used.

       -n, --nofsck
	      Avoid the filesystem check before the resize  operation.	 A  filesystem	check  is
	      mandatory  before  resize2fs(8),	but  is  optional  for	ext2resize(8), and is not
	      allowed for ext2online(8) because the filesystem is mounted.  Useful 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.

       --version
	      Print version number and exit successfully.

DIAGNOSTICS
       e2fsadm	calls  e2fsck(8),  lvextend(8),  lvreduce(8), and resize2fs(8), ext2resize(8), or
       ext2online(8) internally.  By default, for  mounted  filesystems  e2fsadm  will	look  for
       resize2fs first, and failing that it will look for ext2resize.  For mounted filesystems it
       will try to run ext2online.  It returns an exit code 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 available
       8  the filesystem is mounted
       9  the filesystem type is not ext2
       10 the e2fsck(8) command is missing or was not found
       11 resize2fs(8) is missing or was not found
       12 unable to run e2fsck(8)
       13 unable to run resize2fs(8)
       14 an error occured while reading the 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
