CPG will grow as needed. Looks to me that the CPG is trying to grow but there is no available system wide free space for it to grab. In other words, seems like the system is full. |

I currently have the following raw capacity available: SSD Total 171,648 GiB Allocated 135,183 GiB Free 36,465 GiB Would it have anything to do with the single failed drive and set allocation etc? Cheers, |

With set size 10+2 you need 12 drives behind a node pair with free space to create space. Look at showpd -c to see how many drives have free capacity. |

Thanks for the assistance, the failed drive was preventing any tunning from taking place. once this was replaced and admitted into the array we were good to go. |

There is a customer advisory that describes this behavior, you will need to login with your HPE passport to read it. https://support.hpe.com/hpesc/docDispla ... 45368en_us I am guessing that you don't have and HPE active support contract? Let me know if your HPE passport can open that link. |
