We are in the process of migrating data from our 7mode filers (8.1.2P4 7-Mode) to our new CDOT filers (8.3.1P1), and we noticed that a few of our 7mode volumes (NFS volumes) do not have the correct language set.
7mode documentation says I can change the language of a volume, however:
Note: If you are changing the NFS character set, you are asked to confirm
your choice, and also whether you want to halt the system so that WAFL_check can be run to check for any files that will no longer be accessible using NFS. The default answer for this question is yes. If you do not want to halt the system, you must enter n.
I'd really prefer to not halt the filer. What are the ramifications of not halting the filer? Can I safely change the language and snapmirror over to the new filers without issue?
Thanks.

You most certainly want to fix that *BEFORE* you get to Clustered ONTAP. Once a volume has its' language set in cDOT, you cannot change it. You must create a new volume and copy it without mirroring (ndmp, scp, etc)

I'm at the point of moving to cDOT soon.
Considering how much trouble it is to change languages on a volume in cDOT, is there a good discussion of the pros and cons of en_US vs. C (posix)?
Darry, care to expand on your choices/reasoning?

Brian:
I don't know if you used FilerView way back in the day (7mode, 7.x), but it had some really horrible defaults. One of those defaults was the language, the default language was ar.UTF-8 (Arabic). Some folks used the CLI to create our volumes, others used FilerView. If you used FilerView and weren't paying attention, you could easily blow right by that screen and wind up with volumes where the language was set to ar.UTF-8; which we apparently did :-(
Our NetApp SE suggested we use C.UTF-8 as the language for the svms, so that's what we did. New volumes are now created with that as the language. For some of our volume migrations where the data sets/volumes are small, we are using robocopy or rsync. We have a handful of very large volumes with millions of files, rsync/robocopy will choke on those so we have to use snapmirror. snapmirror sets the language on the destination volume to that of the source volume so we wind up with volumes on our new cluster that have a language of ar.UTF-8.
To date, this hasn't been a problem, and I don't think it will be an issue if I were to convert the 7mode volumes to C.UTF-8 before I snapmirror them over. I'm just trying to understand the ramifications of not rebooting the 7mode head after I change the language.
