Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

ERROR: parent subvol is not reachable from inside the root subvol
Not an error I've seen before or that makes much sense to me at first glance, might want to take this to https://github.com/kdave/btrfs-progs/issues or the mailing list?

Understanding btrfs with uneven disk sizes
You can test it by allocating the space to see if it can use it all: e.g. fallocate -l 3.8t /mnt/elfstone2/butts should succeed. If it does, then it's probably fine even if the balance didn't do what it should have. If not and you run out of space with some unallocated space left on only one device, not so much. If its the same bug I saw that means if your fs was created pre kernel 5.19, it will not allocate correctly on >5.19 until the array is rebuilt under the newer kernel.

What does the btrfs autodefrag option actually do?
Mount options should be documented either at https://btrfs.readthedocs.io/en/latest/Administration.html or at the manual page section 5 (man 5 btrfs). Autodefrag is in section https://btrfs.readthedocs.io/en/latest/Administration.html#btrfs-specific-mount-options . In case you find more information missing, unclear, lacking cross-references please open an issue at https://github.com/kdave/btrfs-progs/issues .

Storage tiering possible with brtfs? Apparently netgear is doing it
thanks. I filled a feature request... https://github.com/kdave/btrfs-progs/issues/610

Sure, btrfs-balance is slow, but this is ridiculous
Resume sort of doesn't work, when you resumed it will have started a fresh balance with a high usage value (check your syslog to confirm).
-
Is it normal for btrfs scrub "bytes scrubbed" to exceed 100%?
That's the hint. It's an unfixed bug with the accounting when scrub is paused and resumed, the relevant issue is I think https://github.com/kdave/btrfs-progs/issues/227 .

Is my backup dead, and gone?
Hoping for a filesystem clone option at some point.

Using btrfs with snapraid, can it protect new data before snapraid scrubs?

Sanity/Understanding check
I've been looking into snapraid-btrfs and snapraid-btrfs-runner.

Tiered storage with mergerfs. Anyone using it? Any recommended scripts to monitor super-fast-nvme mount and sync to spinning-rust disks?
- Use https://github.com/automorphism88/snapraid-btrfs which allows me to run 'snapraid' sync from a brtfs-snaptshot so the system can continue running 24/7 while doing parity maintenance tasks.

This is your friendly reminder to BACK UP YOUR LIBRARIES. Do it today.
Add btrfs into the mix with snapraid-btrfs and now you have atomic snapshots and don't have to worry about new writes corrupting your snapshot data for that missing drive. And then automate it with snapraid-btrfs-runner, which will automatically check if more than X files were deleted, run the sync, run a scrub, and email you the result. After all that I use Borg Backup to backup content I generate (stuff I can't just download again) to a PC I have at my dad's house off-site. Which has already come in handy when a logical volume for my container data destroyed itself for some unknown reason (that was data on a RAID1 baked LVM volume with XFS as the filesystem).

What filesystem should I use with MergerFS?
Btrfs for data and ext4 for parity is one decent combination (btrfs should be absolutely safe enough on single drives) and you can also use something like https://github.com/automorphism88/snapraid-btrfs (read the FAQ if you're wondering why).

Question about datacow and nodatasum
Because I need snapshots and I plan to use snapraid-btrfs.
What are some alternatives?

snapraid-runner - Python script for SnapRAID cronjobs
jdupes - A powerful duplicate file finder and an enhanced fork of 'fdupes'.
snapraid - A backup program for disk arrays. It stores parity information of your data and it recovers from up to six disk failures
systemd-swap - Script for creating hybrid swap space from zram swaps, swap files and swap partitions.
