-d|-Dsize
Specifies that the data section of the filesystem should be resized. If the -Dsize 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 -rextsize=nnnn.
-i The new log is an internal log (inside the data section). [NOTE:Thisoptionisnotimplemented]-l|-Lsize
Specifies that the log section of the filesystem should be grown, shrunk, or moved. If the -Lsize
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:Theseoptionsarenotimplemented]-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 -imaxpct=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. Seeoutputexamplesbelow.-r|-Rsize
Specifies that the real-time section of the filesystem should be grown. If the -Rsize 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.
