About file system disk layouts
The disk layout is the way file system information is stored on disk. On Veritas File System (VxFS), several disk layout versions are supported to provide new features and specific UNIX environments.
You can use one of the following commands to upgrade the disk layout version.
vxupgrade | Upgrades an existing VxFS file system to a supported disk layout version while the file system remains online. See the vxupgrade(1M) manual page. |
vxfsconvert | Upgrades a no-longer supported disk layout version to a supported version while the file system is not mounted. The vxfsconvert command can also be used to convert a native file system (ext2, ext3, and ext4) to VxFS, while the file system is not mounted. See the vxfsconvert(1M) manual page. |
Table: Supported disk layout versions lists the supported disk layout versions.
