[gpfsug-discuss] CCR error messages after mmsdrrestore

[Oesterlin, Robert]

Following up to my own problem….

It would appear mmsdrrestore doesn’t work (well) with quorum nodes in a CCR enabled cluster. So:

change node to non-quorum
mmsdrrestore
change back to quorum

Hey IBM – how about we document this!

Yea – turning of CCR means shutting down the entire cluster. Not an option.

CCR is VERY POORLY documented.

I would try switching from CCR to primary/secondary config servers, maybe delete the paxos files, and then back to CCR.


I believe that's how I got out of a similar situation on a v4.1.1.x installation this january..
