I have a BTRFS RAID5 setup (no mdadm) with four disks (the fifth failed). Now I am trying to recover the files but as soon as I try to rsync the files over to another disk, the system hangs after copying the first file. The strange thing is the "sending file list" works as expected but then it locks up. I'm using Antergos (Arch Linux) with the most recent stable kernel.
I also tried to rebuild the array: instant lockup. Tried to remove the missing device and rebuild: same result.
Is there any way to recover the data?
