- _x_f_s__g_r_o_w_f_s expands an existing XFS filesystem (see _x_f_s(4)). The _m_o_u_n_t-
- _p_o_i_n_t argument is the pathname of the directory where the filesystem is
- mounted. The filesystem must be mounted to be grown (see _m_o_u_n_t(1M)).
- The existing contents of the filesystem are undisturbed, and the added
- space becomes available for additional file storage.
-
- The options to _x_f_s__g_r_o_w_f_s are:
-
- ----dddd, ----DDDD _s_i_z_e
- Specifies that the data section of the filesystem should be grown.
- If the ----DDDD _s_i_z_e 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 blocks.
-
- ----eeee Allows the real-time extent size to be specified. In _m_k_f_s__x_f_s(1M)
- this is specified with ----rrrr eeeexxxxttttssssiiiizzzzeeee====_n_n_n_n.
-
- ----iiii The new log is an internal log (inside the data section).
-
- ----llll, ----LLLL _s_i_z_e
- Specifies that the log section of the filesystem should be grown,
- shrunk, or moved. If the ----LLLL _s_i_z_e 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 _m_k_f_s(1M)
- time). If neither ----iiii nor ----xxxx is given with ----llll, the log continues to
- be internal or external as it was before.
-
- ----mmmm Specify a new value for the maximum percentage of space in the
- filesystem that can be allocated as inodes. In _m_k_f_s__x_f_s this is
- specified with ----iiii mmmmaaaaxxxxppppcccctttt====_n_n.
-
- ----nnnn 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.
-
- ----rrrr, ----RRRR _s_i_z_e
- Specifies that the real-time section of the filesystem should be
- grown. If the ----RRRR _s_i_z_e 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 _x_f_s__g_r_o_w_f_s operation.

- ----xxxx The new log is an external log (in an XLV log subvolume).
-
- _x_f_s__g_r_o_w_f_s is most often used in conjunction with logical volumes (see
- _x_l_v(7M) or _l_v(7M)). 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 done through the mechanism
- of logical volumes. If the filesystem already resides on a logical
- volume, the volume is simply extended using _m_k_l_v(1M) or _x_l_v__m_g_r(1M). If
- the filesystem is currently on a regular partition, it is necessary to
- create a new logical volume whose first member is the existing partition,
- with subsequent members being the new partition(s) to be added. Again,
- _m_k_l_v or _x_l_v__m_g_r is used for this. In either case _x_f_s__g_r_o_w_f_s is run on
- the mounted filesystem, and the expanded filesystem is then available for
- use.
