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.
