Upgrading disk layout versions
In this release, you can create and mount only file systems with disk layout version 14, 15, 16, 17, and 18. You can local mount disk layout version 7, 8, 9, 10, 11, 12, and 13 to upgrade to a later disk layout version.
Note:
If you plan to use 64-bit quotas, you must upgrade to the disk layout version 10 or later.
Disk layout version 7, 8, 9, 10, 11, 12, and 13 are deprecated and you cannot cluster mount an existing file system that has any of these versions.
To upgrade a cluster file system from any of these deprecated versions, you must local mount the file system and then upgrade it using the vxupgrade utility or the vxfsconvert utility.
The vxupgrade utility enables you to upgrade the disk layout while the file system is online. However, the vxfsconvert utility enables you to upgrade the disk layout while the file system is offline.
If you use the vxupgrade utility, you must incrementally upgrade the disk layout versions. However, you can directly upgrade to a desired version, using the vxfsconvert utility.
For example, to upgrade from disk layout version 7 to a disk layout version 10, using the vxupgrade utility:
# vxupgrade -n 8 /mnt # vxupgrade -n 9 /mnt # vxupgrade -n 10 /mnt
See the vxupgrade
(1M) manual page.
See the vxfsconvert
(1M) manual page.
Note:
Arctera recommends that before you begin to upgrade the product version, you must upgrade the existing file system to the highest supported disk layout version. Once a disk layout version has been upgraded, it is not possible to downgrade to the previous version.
Use the following command to check your disk layout version:
# fstyp -v /dev/vx/dsk/dg1/vol1 | grep -i version
For more information about disk layout versions, see the Storage Foundation Administrator's Guide.
