April 22, 20242 yr I've been using a ZFS pool (12x 4TB SAS HDD) as my primary storage (user, appdata, media, etc.) while my array (1x 1TB SSD + 1x 1.2TB HDD for parity) just held AppData backups. I know, I know, it's not how this was intended to be used but I thought the pool would be significantly more performant and ended up here. I want to move back to a traditional setup with the 12 drives being on the array and the SSD + extra drive being cache. Biggest issue is my pool has about 27TB out of about 36 used, mostly for Plex media with a bit of appdata and personal files. I have no idea how to go about fixing up my array without transferring all this data elsewhere. I do have 2x 12TB external HDDs but they're connected over USB 2.0 (old server) and my network is all gigabit. Even if I deleted some media or got another external HDD, my server would be down for so long. srv-host-0-diagnostics-20240422-1818.zip Edited April 22, 20242 yr by Daniel Thiberge

The flexibility is what you lose with a zfs pool, it's one thing that can't be broken down or (easily) expanded. Do you have extra SAS/SATA ports to shuck the externals and connect them internally?

Do you have extra SAS/SATA ports to shuck the externals and connect them internally? Nah, the server is filled to the brim. That makes sense, was my risk to take I guess haha. That said, I was looking to switch to a mini PC and DAS setup soonish anyway.* Technically my ZFS pool in Unraid is just a normal pool, and therefore OS agnostic right? It’d be great if I could move my boot USB to a new system, boot the current server in a live environment, import the pool, and transfer over the network. *Doing my research so I know what I’m getting into first.. I know it’s also not recommended.
