Re: Releasing dedupe data store space

I rebooted both nodes of the 3PAR sequentially and afterwards the stuck tasks had been gone. And luckily after the reboot the DDS got automatically deleted leading to unitialized chunklets. So despite the worrying about the "invalid" error message I'm lucky to have at least some disk space...

Once that is done, all the chunklets will become uninitialized and it will initialize them (similar to what happens during disk add-on without the tunesys).

Is there someone having experience on any performance impact for the final release of dedup version 2 space? I was finally able to migrate all data on one side of a peer-persistence configuration to new dedup version 3. And now everything is running fine on new dedup version 3 LUNs. But the old CPG ...
