Thanks Jeff, here's the output:
~# strace -e ioctl eject /dev/ubd2
ioctl(3, CDROMEJECT, 0) = -1 EIO (Input/output error)
ioctl(3, SG_GET_VERSION_NUM, 0x7f7f85f82c) = -1 EINVAL (Invalid argument)
ioctl(1, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo ...}) = 0
not an sg device, or old sg driver
ioctl(3, FDEJECT, 0x40577980) = -1 EINVAL (Invalid argument)
ioctl(3, MGSL_IOCGPARAMS or MTIOCTOP or SNDCTL_MIDI_MPUMODE,
0x7f7f864490) = -1 EINVAL (Invalid argument)
eject: unable to eject, last error: Invalid argument
Process 1139 detached
Sincerely,
Flavio
