What kind of raid profiles are in use on this filesystem?

[David C. Partridge]

Hardware Raid 5  It may have got confused because I did btrfs subvolume delete of a few subvolumes just before I started the scrub?

Mind to share the following commands output?

# btrfs fi df <mnt>
# btrfs fi usage <mnt>
# uname -a

I'm considering if it's RAID56 or other profiles causing the problem.

Thanks,

What version of btrfs-progs? Looks like 96ed8e801 fixed an issue with
ETA reporting, which I'm guessing made it into btrfs-progs 5.2 or
5.2.1?

Well, if you can find a newer version that'd help determine if it's a
current bug or one long since fixed. Current version is 5.18.1.
