Creating a VxFS file system

Always specify vxfs as the file system type to take advantage of Quick I/O, Storage Rollback, online administration, fast recovery of the VxFS file system, and superior reliability features.

Before creating a file system, see the following notes:

Usage notes

See the mkfs(1M) and mkfs_vxfs(1M) manual pages for more information about the options and variables available for use with the mkfs command.
See the mount(1M) and mount_vxfs(1M) manual pages for more information about mount settings.

To create a VxFS file system on an existing volume

Use the mkfs command as follows:
```
# /usr/sbin/mkfs -F vxfs [generic_options] \
[-o specific_options] special [size]
```
where:
- vxfs is the file system type
- generic_options are the options common to most file systems
- specific_options are options specific to the VxFS file system
- special is the full path name of the raw character device or VxVM volume on which to create the file system (for example, /dev/vx/rdsk/PRODdg/db01)
- size is the size of the new file system (optional)
If you do not specify size, the file system will be as large as the underlying volume or device partition.

For example, to create a VxFS file system that has an 8 KB block size and supports files larger than 2 GB on the newly created db01 volume:
```
# /usr/sbin/mkfs -F vxfs -o largefiles,bsize=8192,\
logsize=2000 /dev/vx/rdsk/PRODdg/db01
```
The -o largefiles specific option allows you to create files larger than 2 GB.

Note:

Because size is not specified in this example, the size of the file system will be calculated automatically to be the same size as the volume on which the file system is created.

The mkfs command displays output similar to the following:
```
version 6 layout
```
```
20480 sectors, 10240 blocks of size 1024, log size 1024 blocks
```
You can now mount the newly created file system.
