I've actually used the vol and aggr rename commands frequently, not in the process of migration. My current environment was\has been in disarray before my arrival and I'm trying to go back and standardize and clean up some things.

That said, in the pretext of migration, perhaps it should be an optional thing to rename the exports/shares?

Rene:

I have seen this behavior and have been simarly frustrated when migrating CIFS volumes from Traditional to Flexvols.

In my opinion, Netapp should NOT be renaming CIFS shares when you change volume names. They do this automatically without warning you or logging.

I know they're doing it because they think they're being helpful; but really the only time I can forsee changing volume names is if you're doing a migration like you're doing. VERY frustrating indeed.

I found myself having to document all the existing shares, and write a script that deletes, then re-creates all the shares and their permissions on the new volume. Hours of work.

Netapp, is there a way to disable this "feature" prior to renaming a volume?

Hello Toasters,

well, the root vol now moved to the new DS14 flex-vol.

But this night I tried to move the data (shares / lun's / exports) from the old /vol/vol0 (trad) via "ndmpcopy -l 0 /vol/vol0 /vol/vol1" and some hour later, "ndmpcopy -l 0 /vol/vol0 /vol/vol1".

Everthing was copied. All Clients where offline, and than I renamed /vol/vol0 -> /vol/vol0old and /vol/vol1 /vol/vol0. Because I thought than after the reboot all shares and luns and nfs-exports are back on /vol/vol0 but now on the new DS14.

Well I failed, I found out that the vol rename also renamed the CIFS Shares Paths and also the LUN paths. So the CIFS clients where still reading from the old FC9 (/vol/vol0old now) and the iSCSI clients where too. Because I did't terminate CIFS and NFS and iSCSI. To be honest, cool renaming feature to prevent stupid germans from losing data ;-)

So, I though be smart forget about the LUNs, they are fine, care about the shares. "CIFS terminate" and replace vol0old -> vol0 in the /etc/cifsconfig_share.cfg. "CIFS restart". "Year! I am the master !" But I was too stupid again. Because now my CIFS Clients got the shares but they could not see any data. And I got no idea why!

So I "vol rename vol0 vol1" and "vol rename vol0old vol0"

And now the CIFS clients connect back to their shares on the old FC9 again.

So whats wrong about my proceedings? And the second question to save time, how to I move the iSCSI LUNs to the new volume?

Thanks,

Rene

If you are using SecureAdmin/Secure FilerView/SSL, you need to restart the secureadmin services when you cross the 7.x line. There was a major code change starting in 7.0 and the service must be manually restarted (a reboot won't do it).

On the FC9 we got one volume /vol/vol0 with root and data on it. Last week we upgraded from ONTAP 6.5.6 to 7.2.1 without problems. Now we want to move our data to the DS14 shelfs. We created one aggr1 with lots of drives. After that we created two new flex vols - /vol/root (20GB) and an /vol/vol1 (1TB) for the data. We copied the root data with no clients on the filer with "ndmpcopy -l0 /vol/vol0/etc /vol/root/etc". Worked fine in 7 minutes. Than we change the booting volume with "vol options /vol/root root". Booting from it, no problem -but now by requsting http://filer-ip/na_admin just the first page came and we were not able to start the FilerView Web-App. So so we switch the root vol again with "vol options /vol/vol0 root" and FilerView works fine. In the message file we found that one: Sat Feb 3 09:16:09 CET [httpd.socket.listener.create:error]: HTTPS Initialization failure; could not create listener socket. Nothing else. Can anybody help?
