I'm putting together a file server and planned on using an ext4 formatted SSD as the boot disk and a spare 2.5" hdd as a scratch disk for things that don't benefit from the speed of a SSD, with mostly read-only files stored in a btrfs pool. From what I've read, data corruption tends to occur while editing large files (like a virtual disk for a VM) due to how copy-on-write is implemented and btrfs is, in theory, well suited to my application. At the same time, a quick search of the forum results in lots of threads about btrfs pools and RAID arrays breaking, so I was hoping to get a better idea of how it's working for people using it.
I didn't find the right solution from the internet.
