Is Using BTRFS on an Ubuntu Server with RAID1 NVMe Boot a Good Idea?

I've been searching for up-to-date opinions on using BTRFS, but most of what I find is outdated info about past issues. I'm considering running an Ubuntu server on a RAID1 NVMe setup with BTRFS. Will this configuration work smoothly?

It should work well! Personally, I lean towards ZFS because I'm more familiar with it, especially on Ubuntu. Just keep in mind that if you’re using Debian or RHEL, it gets a bit trickier since ZFS isn't included out of the box.

Historically, BTRFS had issues with RAID5 and RAID6 setups, but RAID1 should be fine. So you shouldn't face any major problems using it on your server.

Yes, BTRFS in RAID1 mode is considered production-ready now! So you should have a smooth experience with your setup.

We did hit a snag recently with BTRFS snapshots. Someone forgot to delete an old snapshot before an OS upgrade, which filled up the disk. Just a heads-up that BTRFS snapshots won't show up in the disk usage reports, so be careful with that!

You'll be good to go! In my experience, our installer has worked with lvm+ext4, ZFS, and BTRFS root filesystems, all without issues.
