NAME

6       xfs_growfs, xfs_info - expand an XFS filesystem
7

SYNOPSIS

9       xfs_growfs  [  -dilnrxV ] [ -D size ] [ -e rtextsize ] [ -L size ] [ -m
10       maxpct ] [ -t mtab ] [ -R size ] mount-point
11       xfs_info [ -t mtab ] mount-point
12

DESCRIPTION

14       xfs_growfs expands an existing XFS filesystem (see xfs(5)).  The mount-
15       point argument is the pathname of the directory where the filesystem is
16       mounted. The filesystem must be mounted to  be  grown  (see  mount(8)).
17       The  existing contents of the filesystem are undisturbed, and the added
18       space becomes available for additional file storage.
19
20       xfs_info is equivalent to invoking xfs_growfs with the -n  option  (see
21       discussion below).

OPTIONS

24       -d | -D size
25              Specifies  that  the  data  section  of the filesystem should be
26              grown. If the -D size option is given, the data section is grown
27              to that size, otherwise the data section is grown to the largest
28              size possible with the -d  option.  The  size  is  expressed  in
29              filesystem blocks.
30
31       -e     Allows the real-time extent size to be specified. In mkfs.xfs(8)
32              this is specified with -r extsize=nnnn.
33
34       -i     The new log is  an  internal  log  (inside  the  data  section).
35              [NOTE: This option is not implemented]
36
37       -l | -L size
38              Specifies  that  the  log  section  of  the filesystem should be
39              grown, shrunk, or moved. If the -L size option is given, the log
40              section  is  changed  to  be that size, if possible. The size is
41              expressed in filesystem blocks.  The size  of  an  internal  log
42              must be smaller than the size of an allocation group (this value
43              is printed at mkfs(8) time). If neither -i nor -x is given  with
44              -l,  the  log  continues  to  be  internal or external as it was
45              before.  [NOTE: These options are not implemented]
46
47       -m     Specify a new value for the maximum percentage of space  in  the
48              filesystem  that can be allocated as inodes. In mkfs.xfs(8) this
49              is specified with -i maxpct=nn.
50
51       -n     Specifies that no change to the filesystem is to be  made.   The
52              filesystem  geometry  is  printed, and argument checking is per‐
53              formed, but no growth occurs.
54
55       -r | -R size
56              Specifies that the real-time section of the filesystem should be
57              grown.  If the -R size option is given, the real-time section is
58              grown to that size, otherwise the real-time section is grown  to
59              the  largest  size  possible  with  the  -r  option. The size is
60              expressed in filesystem blocks.  The filesystem does not need to
61              have  contained a real-time section before the xfs_growfs opera‐
62              tion.
63
64       -t     Specifies an alternate mount table file (default is /proc/mounts
65              if  it  exists, else /etc/mtab).  This is used when working with
66              filesystems mounted without writing to /etc/mtab file - refer to
67              mount(8) for further details.
68
69       -V     Prints the version number and exits. The mount-point argument is
70              not required with -V.
71
72       xfs_growfs is most often used in conjunction with logical volumes  (see
73       md(4)  and lvm(8) on Linux).  However, it can also be used on a regular
74       disk partition, for example if a  partition  has  been  enlarged  while
75       retaining the same starting block.
76

PRACTICAL USE

78       Filesystems  normally  occupy all of the space on the device where they
79       reside. In order to grow a filesystem, it is necessary to provide added
80       space  for it to occupy. Therefore there must be at least one spare new
81       disk partition available. Adding the space is often  done  through  the
82       use of a logical volume manager.
