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. |

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