The heketi logs don't seem to cover the error condition reported. The error emitted 'Unable to determine number of logical volumes in thin pool' is only reported when the command "lvs --options=lv_name,thin_count --separator=:" fails. However, I can not find any lvs commands issued in the attached logs.
In addition the sosrepots attachment appears to refer to a local path.
Can you reproduce and attach a heketi log from immediately after the failure? Thank you.
