Thank you for that info Ducan! I did the restore on the whole drive
and it errored out on me. I'll try the restore on some key files (audo
mostly) and see what i can get off of it.
Is there a fix for the bad tree block error, which seems to be the
root (pun intended) of all this?

It looks like a bug to me if btrfs needs to reload module to clean up
the device list. If a user buil

I am getting some "parent transid verify failed"-errors. Is there any

Hi,
It's well-known that btrfs doesn't directly support swap files. However, a
