At the user end there is no way. unless you want to use gdb and dump
the fs_uuids and check.
Submitted these patches as of now to obtain from the logs. Will
help in the situation when device is missing at the time of mount.
Btrfs: check error before reporting missing device and add uuid
Btrfs: log when missing device is created
For long term we have sysfs interface, patches are in the ML if you
want to tests.
Good luck.
