Creating a VxFS file system


Creating a VxFS file system
Prev	Appendix A. Quick Reference	Next

The mkfs command creates a VxFS file system by writing to a special character device file. The special character device is a location or character device node of a particular storage device. mkfs builds a file system with a root directory and a lost+found directory.

Before running mkfs, you must create the target device. Refer to your operating system documentation for more information. If you are using a logical device (such as a VxVM volume), see the VxVM documentation for instructions on device initialization.

See the mkfs(1M) and mkfs_vxfs(1M) manual pages.

To create a file system

Use the mkfs command to create a file system:

  mkfs [-F vxfs] [-m] [generic_options] [-o specific_options] \
  special [size]

-F vxfs	Specifies the VxFS file system type.
-m	Displays the command line that was used to create the file system. The file system must already exist. This option enables you to determine the parameters used to construct the file system.
generic_options	Options common to most other file system types.
-o specific_options	Options specific to VxFS.
-o N	Displays the geometry of the file system and does not write to the device.
-o largefiles	Allows users to create files larger than two gigabytes. The default option is largefiles.
special	Specifies the special device file location or character device node of a particular storage device.
size	Specifies the number of 512-byte sectors in the file system. If size is not specified, mkfs determines the size of the special device.
