[Lustre-discuss] Upgrading from 1.6.3 to 1.6.4 needs --writeconf

[Roger Spellman]

In the Lustre manual, http://dlc.sun.com/pdf/820-3681/820-3681.pdf,
section 13.3 is titled "Upgrading Lustre from 1.6.3 to 1.6.4".  Step 6
is:

 

     tunefs.lustre --mgs --writeconf --mgs --mdt --fsname=sunfs /dev/sdb

 

What is the purpose of the --writeconf?

 

Is this needed to do other upgrades, say from 1.6.4.3 to 1.6.5 or to
1.6.6?

 

If it is only needed for the upgrade from 1.6.3 to 1.6.4, can someone
please update the manual to say this?

Thanks.
