Little question here : When we do some maintenance and space reclaim on some lun, the Used column is decreasing as long as the reclaim operation is running on the OS/Hypervisor side. But the Rsvd column decrease when the array run it's defrag task. Is there a way to force that, in case of someone messed up with a lun and we need to recover some space quickly? Because until the Rsvd is not dropped, running a compact cpg will not release all the space? right? |

No you can't influence the reclaim process directly and a compact CPG won't return space until 128MB contiguous regions are available. One option is to convert a TPVV to a FPVV and then back to TPVV which will force a defrag. However you need additional space to do this. The other option is to have some temporary sacrificial FPVV volumes which can be deleted in an emergency to free space. |
