On rollout deployed reversers. Noticed left pull and used heavier braking on RH side. Aircraft tracked fine down centerline. Captain advised one reverser inop. Walk-around prior to flight revealed no indication that No. 2 reverser had been inadvertently locked out. On ground post-flight walk-around verified that reverser lockout pins on No. 2 engine were NOT extended showing red. Mechanic found hydraulics lockout in place after opening cowling. This would not be visible during an external walk-around inspection. This is a procedural issue. During maintenance there is probably a checklist for this and it was simply overlooked; perhaps due to fatigue.
A321 First Officer reported that right engine reverser failed to deploy. Post-flight inspection revealed that the reverser was locked out in a manner that was not visible during preflight.
