Hello;

I've installed 11.23 Sept 2006 and the default jfs is 4.1, I need to have jfs and adv-jfs 3.5, how do I remove 4.1 and replace it with 3.5

thanks much;
Ike Leong

Ikeleong,

Sept 2006 version defaults to 4.1, before that jfs 3.5 or 4.1 was a selectable option.

I am not sure if it's possible to go back.

I know that this command is used to convert forward:

vxfsconvert ( for more info take a look at the man man )

But I am not that sure is going to work backwards.

You might want to read carefully on the manpage.

Regards,

Jaime.

Hello ikeleong,

As in all JFS versions till date, you can only upgrade the vxfs versions with vxupgrade(1M).
If you need a file system with version 3.5, then you will need to explicity specify it at the time of running mkfs_vxfs(1M) command.

If you are using SAM to create the file systems, then it will default to version 4.1 version and you might want to exercise caution with the tool.

HTH,
Sanjay
