Hi guys. I was wondering, are there any recommended best practices when using Raid5/6 on BTRFS?
I intend to build a 4 Disk BTRFS Raid5 array, but that's just going to be as a backup for my main ZFS Server. So the data on it is not important. I just want to see how RAID5 will behave over time. That being said, are there any recommended best practices when deploying btrfs with raid5? According to the wiki a good recommendation seems to be to have metadata as RAID1 and data as RAID5. Other than that, are there any mount options which should be used or completely avoided when using raid5/6? (autodefrag,commit=,...) Anything to consider when using realtime compression? Balancing issues? e.g. should you always do a full balance (when you decide you need one)? Whats the best/proper way to replace a failing disk? What about a sudden faulty disk? e.g. won't spin up anymore. Just use btrfs replace as it says in the wiki? Thanks guys.
