Frenchie Posted April 19, 2020 Share Posted April 19, 2020 New to this, looking for a little confirmation - On hand I have 2 x 10Tb, 2 x 500Gb SSD & 2 x 256Gb SSD. I’ve setup the 2 x 256Gb drives in a RAID1 cache pool. But, realizing now I may want to setup all 4 SSDs as a RAID10 cache pool. Sounds like I would be losing 500Gb by doing so, but gaining in performance, though RAID10 may still have some performance issues to be worked out. RAID5 doesn’t seem like a good idea with Brtfs at the moment, but please correct me if I’m wrong. The cache pool would be for VMs, docker, and media scratch. Looks like I could upgrade the 2 x 256Gb SSDs down the line without wiping the cache pool? Is there a better approach? Thank you! Quote Link to comment

Frenchie Posted April 19, 2020 Author Share Posted April 19, 2020 Thank you, I may stick with the RAID10 cache pool approach. My problem is that I put those 2 x 500GB SSDs in my array, and now they've got data on them. Looks like moving that data around (onto that 10TB HDD in my array) is going to be a little tricky. Any recommendation there would be greatly appreciated. Quote Link to comment
JorgeB Posted April 20, 2020 Share Posted April 20, 2020 Looks for Unbalance, it's probably the easiest way. Quote Link to comment
