Could you add 'debug ms = 1', 'debug rbd = 20', and 'log file =
/tmp/librbd.log' to the [client] section of your ceph.conf?
That log should tell us where the error is happening.
Paolo from Redhat / qemu means:
"
The discard request is failing. Please check why with a breakpoint on
rbd_aio_discard_wrapper or scsi_handle_rw_error for example.
"
