Re: How to modify file system layout ?

Hi,

No it is not possible.

Capture from "man vxupgrade"

Disk layout versions cannot be downgraded, for example, you cannot change a file system from disk layout version 4 to disk layout version

Re: How to modify file system layout ?

hi,

is that not the VxFS 4.1 file system which employs Disk Layout Version 6? if so, why do u need to downgrade since it also supports version 4 and 5.

btw, did u apply a patch to upgrade from version 4 to 6?

regards.

Hi Again,

It got posted a bit earlier.


Disk layout versions cannot be downgraded, for example, you cannot change a file system from disk layout version 4 to disk layout version 3.

Hi,

The answer is NO.

The disk layout versions cannot be downgraded.

Hope this information can help you.

Hi,

The vxupgrade command can upgrade an existing Version 3 VxFS file
system to the Version 4 layout while the file system remains online.
vxupgrade can also upgrade a Version 2 file system to the Version 3
layout. See vxupgrade(1M) for details on upgrading VxFS file
systems.You cannot downgrade a file system that has been upgraded.

The above is an extract from

Hope this helps,

Downgrade is not possible with VXFS.
