VERITAS File System 3.5 (HP OnlineJFS/JFS 3.5) Installation

Installing From the Support Plus CD-ROM

Upgrading the VxFS Disk Layout

VxFS 3.5 allows mounting of three file system disk layouts:

• Disk layout Version 2 (with quotas or without quotas)

• Disk layout Version 3

• Disk layout Version 4

However, making new file systems with disk layout Version 2 or Version 3 is not allowed under VxFS 3.5. Any

new file system created using VxFS 3.5 has disk layout Version 4. You can also explicitly specify the Version 4

disk layout using the mkfs command:

# mkfs -F vxfs -o version=4 /devicename

You can determine the file system layout using the fstyp command:

# fstyp -v /dev/vx/dsk/dg1/vol3

vxfs

version: 4

f_fsindex: 7

f_size: 512000

In the above example output, “version 4” means the Version 4 file system disk layout.

Use the vxupgrade command to upgrade an existing VxFS disk layout to disk layout Version 4 while the file

system remains online:

# vxupgrade -n 4 /mount_point

You can also use the vxfsconvert command to upgrade file systems while they are offline. See the

vxfsconvert (1M), vxupgrade (1M), and fsadm (1M) manual pages for more information on upgrading VxFS

file systems.
