Creating VxFS file system for deploying DB2


Creating VxFS file system for deploying DB2

To create a Veritas File System (VxFS) file system, use the mkfs or the mkfs_vxfs commands.

Review the file system creation guidelines before creating VxFS file systems.

See File system creation guidelines for deploying DB2.

To create a VxFS file system on an existing volume

Use the mkfs command as follows:

AIX

# /usr/sbin/mkfs -V vxfs generic_options\
 -o specific_options special size

Linux

# /usr/sbin/mkfs -t 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 the VxVM volume on which to create the file system
(optional) size is the size of the new file system

If you do not specify size, the file system will be as large as the underlying volume.

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 -V vxfs -o largefiles,bsize=8192,logsize=2000 \
 /dev/vx/rdsk/PRODdg/db01

The -o largefiles option allows you to create files larger than 2GB.

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.
