15 xfs_growfs expands an existing XFS filesystem (see xfs(5)). The mount-
16 point argument is the pathname of the directory where the filesystem is
17 mounted. The filesystem must be mounted to be grown (see mount(8)).
18 The existing contents of the filesystem are undisturbed, and the added
19 space becomes available for additional file storage.
20
22 -d | -D size
23 Specifies that the data section of the filesystem should be
24 grown. If the -D size option is given, the data section is grown
25 to that size, otherwise the data section is grown to the largest
26 size possible with the -d option. The size is expressed in
27 filesystem blocks.
28 -e Allows the real-time extent size to be specified. In mkfs.xfs(8)
30 this is specified with -r extsize=nnnn.
31 -i The new log is an internal log (inside the data section).
33 [NOTE: This option is not implemented]
34 -l | -L size
36 Specifies that the log section of the filesystem should be
37 grown, shrunk, or moved. If the -L size option is given, the log
38 section is changed to be that size, if possible. The size is
39 expressed in filesystem blocks. The size of an internal log
40 must be smaller than the size of an allocation group (this value
41 is printed at mkfs(8) time). If neither -i nor -x is given with
42 -l, the log continues to be internal or external as it was
43 before. [NOTE: These options are not implemented]
44 -m Specify a new value for the maximum percentage of space in the
46 filesystem that can be allocated as inodes. In mkfs.xfs(8) this
47 is specified with -i maxpct=nn.
48 -n Specifies that no change to the filesystem is to be made. The
50 filesystem geometry is printed, and argument checking is per‐
51 formed, but no growth occurs. See output examples below.
52 -r | -R size
54 Specifies that the real-time section of the filesystem should be
55 grown. If the -R size option is given, the real-time section is
56 grown to that size, otherwise the real-time section is grown to
57 the largest size possible with the -r option. The size is
58 expressed in filesystem blocks. The filesystem does not need to
59 have contained a real-time section before the xfs_growfs opera‐
60 tion.
61 -t Specifies an alternate mount table file (default is /proc/mounts
63 if it exists, else /etc/mtab). This is used when working with
64 filesystems mounted without writing to /etc/mtab file - refer to
65 mount(8) for further details.
66 -V Prints the version number and exits. The mount-point argument is
68 not required with -V.
69 xfs_growfs is most often used in conjunction with logical volumes (see
71 md(4) and lvm(8) on Linux). However, it can also be used on a regular
72 disk partition, for example if a partition has been enlarged while
73 retaining the same starting block.
74
76 Filesystems normally occupy all of the space on the device where they
77 reside. In order to grow a filesystem, it is necessary to provide added
78 space for it to occupy. Therefore there must be at least one spare new
79 disk partition available. Adding the space is often done through the
80 use of a logical volume manager.
