October 27, 20223 yr Hi! I have just added a 1TB SDD into my cache which originally consisted of a single 120GB SSD. It has been configured as RAID1. The GUI now shows it as a 560GB pool size. The free space and used space however show as 39.5GB and 80GB respectively. I'm assuming this is a display bug with the total size as I would assume the total size remains as 120GB being the size of the smallest drive. I tried to add this topic to the bugs section but it was greyed out. And don't worry. I plan to swap out the 120GB drive shortly with another 1TB drive Cheers,
October 28, 20223 yr Community Expert Solution It's a known issue with different size devices, used and free space will be correct.
October 28, 20223 yr Community Expert It was much worse before since the free space would be relative to the displayed pool size minus the used space, it's complicated to show everything correctly with btrfs and different size devices.
