[gpfsug-discuss] Migrate 3.5 to 4.2 and LTFSEE toSpectrumArchive

Thu Aug 18 18:50:12 BST 2016

Samba as supported in Spectrum Scale uses the "autorid" module for 
creating internal id mappings (see man idmap_autorid for some details).

Officially supported are also methods to retrieve id mappings from an 
external server: 
https://www.ibm.com/support/knowledgecenter/en/STXKQY_4.2.1/com.ibm.spectrum.scale.v4r21.doc/bl1adm_adfofile.htm

The earlier email states that they have a " .tdb backend for id mapping on 
their current server. ". How exactly is that configured in Samba? Which 
Samba version is used here?

So the plan is to upgrade the cluster, and then switch to the Samba 
version provided with CES? Should the same id mappings be used?

We are currently running samba on the 3.5 node, but wanting to migrate 
everything into using CES once we get everything up to 4.2.

I am in process of migrating from 3.5 to 4.2 and LTFSEE to Spectrum 
Archive.

1 node cluster (currently) connected to V3700 storage and TS4500 backend. 
We have upgraded their 2nd node to 4.2 and have successfully tested 
joining the domain, created smb shares, and validated their ability to 
access and control permissions on those shares. 
They are using .tdb backend for id mapping on their current server. 

I'm looking to discuss with someone the best method of migrating those tdb 
databases to the second server, or understand how Spectrum Scale does id 
mapping and where it stores that information.

Any hints would be greatly appreciated.
