OK so you've umounted the file system, reconnected all devices,
mounted the file system normally, and there are no problems reported
in dmesg?
If so, yes I agree that a scrub should probably work, it should fix
any problems with the simulated corrupt device, and also not crash.
What if you umount, and run btrfs check without --repair, what are the
results? This is btrfs-progs 4.3.1?
The output from dmesg after mounting
[ 546.857533] BTRFS info (device sdg1): disk space caching is enabled
[ 546.872126] BTRFS: bdev /dev/sde1 errs: wr 10, rd 0, flush 0, corrupt

[ 546.872165] BTRFS: bdev /dev/sdb1 errs: wr 16, rd 7, flush 0, corrupt

This is the output I get from btrfs check /dev/sdb1 > somefile.output ....
(note the filesystem was checked in unmounted state)
