NLS Posted October 10, 2022 Share Posted October 10, 2022 I would like to (re)open this discussion, hopefully people that have already done it will chime in and tell us what is positive and negative in this move. So to organize this a bit: 1) Official docs, claim that BTRFS is not as robust as XFS yet. But they use BTRFS by default in cache (where the risk is considered smaller? Yet most people's VMs are there). Is this claim still valid in Oct 22? Or should UNRAID move to default BTRFS "soonish"? 2) Compression, while default in most "competing" solutions that use ZFS, is not even a (GUI) option in UNRAID. People that use it (I believe there are a few), feel it should be an option that can be set "officially"? (or even default) 3) Recovery options when moving to BTRFS or moving to BTRFS with compression. Are they available? Is it the same as with XFS? 4) Load on CPU? Actual saving benefits? Some people claim that for certain uses, writing with compression (or reading compressed) can even speed up things, as less data are read from the actual slow media (or writen to it) and the load moves to the CPU. In practice? 5) For people that have actually done it: Can someone give a streamlined stupid-proof process on how to achieve BTRFS with compression in UNRAID? Quote Link to comment
