Hi all! I am trying to create a very simple script that would alert in case of disk failures from a RAID Btrfs. Digging into the code, I have noticed that the "btrfs fi sh" command should display a warning if there is a missing disk. However, testing in a Qemu, I used "drive_del" via QMP to remove a "live" SCSI drive, already mounted as part of a RAID10 array, the "fi sh" command still gave no indication that the drive is missing. Then, I tried removing a scsi disk from the host via "echo 1 >/sys/block/sdX/device/delete" to actually make the kernel SCSI host forget about it, and "fi sh" still doesn't show anything. I have tested using btrfs-progs v3.12 and kernel 3.13.0. Do you guys know what's wrong with the setup explained above or do you have any indication on how to detect if there is a failing disk, part of a Btrfs RAID?
