I have a 3x1 TB disk raid 5 btrfs raid
I have a device causing i/o errors so what I had done is add a new device:
btrfs device add:
btrfs device add /dev/sdf /media/raid -f

and now I'm trying to remove the bad device:
btrfs device delete /dev/sdb /media/raid/

and I get:
ERROR: error removing the device '/dev/sdb' - Input/output error

the first time it took 10 minutes befre that message was displayed, at which point I had gotten plenty of these messages:
[ 1188.965393] BTRFS warning (device sdb): csum failed ino 423 off 73184092160 csum 499875984 expected csum 2944674917

I have:
/dev/sdb 3.7T 196G 2.5T 8% /media/raid
