\f3\-d\f1, \f3\-D\f1 \f2size\f1
36
Specifies that the data section of the filesystem should be grown.
40
option is given, the data section is grown to that size, otherwise

the data section is grown to the largest size possible.

Allows the real-time extent size to be specified.

59
Specifies that the log section of the filesystem should be grown,

Adding the space is often done through the use of a logical volume manager.
