Upgrading disk layout versions


Upgrading disk layout versions
Prev	Performing post-upgrade tasks	Next

In this release, you can create and mount only file systems with disk layout Version 7, 8, 9, and 10. You can only local mount disk layout Version 6 only to upgrade to a later disk layout version.

Note:

If you plan to use 64-bit quotas, you must upgrade to the latest disk layout Version 10. The use of 64-bit quota on earlier disk layout versions is deprecated in this release.

Disk layout Version 6 has been deprecated and you cannot cluster mount an existing file system that has disk layout Version 6. To upgrade a cluster file system with disk layout Version 6, you must local mount the file system and then upgrade the file system using the vxupgrade utility to a later version.

To upgrade the disk layout versions

To get to disk layout Version 10 from Version 6. You must incrementally upgrade the disk layout of this file system. For example:
```
# vxupgrade -n 7 /mnt
# vxupgrade -n 8 /mnt
# vxupgrade -n 9 /mnt
# vxupgrade -n 10 /mnt
```

See the vxupgrade(1M) manual page.

You must upgrade any existing file systems with disk layout Version 4 to disk layout Version 7 or later using the vxfsconvert command.

See the vxfsconvert(1M) manual page.

Note:

Veritas recommends that you upgrade existing file systems to the highest supported disk layout version prior to upgrading to this release. Once a disk layout version has been upgraded, it is not possible to downgrade to the previous version.

You can check which disk layout version your file system has by using the following command:

# fstyp -v /dev/vx/dsk/dg1/vol1 | grep -i version
