xfs_growfs(8) System Manager's Manual xfs_growfs(8)
xfs_growfs - expand an XFS filesystem
xfs_growfs [ -dilnrx ] [ -D size ] [ -e rtextsize ] [ -L size ] [
-m maxpct ] [ -t mtab ] [ -R size ] [ mount-point | block-device ]
xfs_growfs -V
xfs_growfs expands an existing XFS filesystem (see xfs(5)). The
mount-point argument is the pathname of the directory where the
filesystem is mounted. The block-device argument is the device
name of a mounted XFS filesystem. The filesystem must be mounted
to be grown (see mount(8)). The existing contents of the
filesystem are undisturbed, and the added space becomes available
for additional file storage.
-d | -D size
Specifies that the data section of the filesystem should be
resized. If the -D size option is given, the data section
is changed to that size, otherwise the data section is
grown to the largest size possible with the -d option. The
size is expressed in filesystem blocks. A filesystem with
only 1 AG cannot be shrunk further, and a filesystem cannot
be shrunk to the point where it would only have 1 AG.
-e Allows the real-time extent size to be specified. In
mkfs.xfs(8) this is specified with -r extsize=nnnn.
-i The new log is an internal log (inside the data section).
[NOTE: This option is not implemented]
-l | -L size
Specifies that the log section of the filesystem should be
grown, shrunk, or moved. If the -L size option is given,
the log section is changed to be that size, if possible.
The size is expressed in filesystem blocks. The size of an
internal log must be smaller than the size of an allocation
group (this value is printed at mkfs(8) time). If neither
-i nor -x is given with -l, the log continues to be
internal or external as it was before. [NOTE: These
options are not implemented]
-m Specify a new value for the maximum percentage of space in
the filesystem that can be allocated as inodes. In
mkfs.xfs(8) this is specified with -i maxpct=nn.
-n Specifies that no change to the filesystem is to be made.
The filesystem geometry is printed, and argument checking
is performed, but no growth occurs. See output examples
below.
-r | -R size
Specifies that the real-time section of the filesystem
should be grown. If the -R size option is given, the real-
time section is grown to that size, otherwise the real-time
section is grown to the largest size possible with the -r
option. The size is expressed in filesystem blocks. The
filesystem does not need to have contained a real-time
section before the xfs_growfs operation.
-t Specifies an alternate mount table file (default is
/proc/mounts if it exists, else /etc/mtab). This is used
when working with filesystems mounted without writing to
/etc/mtab file - refer to mount(8) for further details.
-V Prints the version number and exits. The mount-point
argument is not required with -V.
xfs_growfs is most often used in conjunction with logical volumes
(see md(4) and lvm(8) on Linux). However, it can also be used on
a regular disk partition, for example if a partition has been
enlarged while retaining the same starting block.
Filesystems normally occupy all of the space on the device where
they reside. In order to grow a filesystem, it is necessary to
provide added space for it to occupy. Therefore there must be at
least one spare new disk partition available. Adding the space is
often done through the use of a logical volume manager.
mkfs.xfs(8), xfs_info(8), md(4), lvm(8), mount(8).
