xfs_growfs(8) System Manager's Manual xfs_growfs(8)
xfs_growfs, xfs_info - expand an XFS filesystem
xfs_growfs [ -dilnrxV ] [ -D size ] [ -e rtextsize ]
[ -L size ] [ -m maxpct ] [ -t mtab ]
[ -R size ] mount-point
xfs_info [ -t mtab ] mount-point
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 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.
xfs_info is equivalent to invoking xfs_growfs with the -n option (see
The options to xfs_growfs are:
-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. The size is expressed in filesystem
-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 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 per-
formed, but no growth occurs.
-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. 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 /etc/mtab).
This is used when working with filesystems mounted without writ-
ing to /etc/mtab file - refer to mount(8) for further details.
xfs_growfs is most often used in conjunction with logical volumes (see
lvm(8) ). However, it can also be used on a regular disk partition,
for example if a partition has been enlarged while retaining the same
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.
