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
grown. If the -D size option is given, the data section is
grown 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.
-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).
