--- title: First Upgrade description: Upgrade to the cluster date: 2026-04-29 slug: first-upgrade --- Today I have upgraded the cluster from 16GB of ram to 48GB of ram. And also I added a new 8TB HDD drive. Now I have an small problem all the media and random files inside the original HDD were inside a proxmox virtual qcow disk which is just a disk file that all the other containers from the proxmox instance had mounted. Now with this new disk I made a ZFS filesystem. The ZFS filesystem is great for servers. It has a lot of features like having on-write compression and decompression and also it is very easy to add new disks to a "zpool" of disks. Right now I'm copying all the files inside the old virtual .qcow disk file onto the new ZFS filesystem that I have made on the new disk. When this finishes, I will wipe the old disk and add it to the ZFS pool. For now it will be on RAID0. These disks are relatively new, so maybe in the far future (in about 3 years) I will consider maybe making a RAID5. I think it should be easy, right? Anyways see ya
