Kicking 15k spindles out of a 10k cpg?

Post by richard612 »

We had a CPG with no rpm spec in its disk filter. It ran with mixed 10k and 15k spindles for a long time. I've since added "-rpm 10k" to the disk filter but I'm struggling to kick the 15k spindles out of the CPG. Any thoughts on how to approach this?

I've not had to do this myself but I think after changing a CPG config you need to run a tune against the CPG to make existing data match the new config. Any new allocations should use the updated config straight away.

Correct. Simple way is just kick off tunesys.

compactcpg hasn't worked and neither has tuning the vv's within the cpg. I'll try a full tunesys and see what happens.
