Creating a File System
The mkfs command creates a VxFS file system by writing to a special character device file. The special character device is a raw disk device or a VERITAS Volume Manager (VxVM) volume. 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.
How to Create a File System
To create a file system, use the mkfs command:
mkfs [-F vxfs] [generic_options] [-o specific_options] special [size]
vxfs
|
The file system type.
|
generic_options
|
Options common to most other file system types.
|
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
|
The character (raw) device or VERITAS Volume Manager volume.
|
size
|
The size of the new file system (in sectors).
|
See the following manual pages for more information about creating VxFS file systems:
Example
To create a VxFS file system 12288 sectors in size on VxVM volume, enter:
# mkfs -F vxfs /dev/vx/rdsk/diskgroup/volume 12288
Information similar to the following displays:
version 6 layout
262144 sectors, 262144 blocks of size 1024, log size 1024 blocks
largefiles supported
At this point, you can mount the newly created file system.
