Converting from regular VxFS file system to MVS

The following procedure describes the conversion of a regular VxFS file system to MVS file system and optionally add new volume to it. Converting a regular VxFS to MVS requires superuser (root) privileges.

For further details on creating and administrating the VxVM Volume Sets and VxFS Multi-Volume Files System, refer to the Veritas Volume Manager Administrator's Guide and Veritas File System Administrator's Guide.

To convert from a regular VxFS file system to MVS

  1. Select a non-MVS file system to convert to MVS and unmount it: 

    # umount /mnt1

  2. Create the volume set:

    # vxvset -g dgname make myvset old_vol

  3. Mount the volume set:

    # mount -F vxfs /dev/vx/dsk/dgname/myvset /mnt1

  4. Upgrade the volume set's file system to Version 6 disk layout: 

    # vxupgrade -n 6 /mnt1

    See the Veritas File System Installation Guide and the vxfsconvert(1M) and vxupgrade(1M) manual pages for information on upgrading VxFS disk layouts:

  5. Add the new volume to the volume set:

    # vxvset -g dgname addvol myvset new_vol

  6. Add the new volume to the file system. You must specify the size of the volume:

    # fsvoladm add /mnt1 new_vol 2g

    where new_vol is the name of the newly added volume and 2g is the size of the volume:

  7. Verify the new volume in the file system:

    # fsvoladm list /mnt1
