Narrative:
Aircraft Y requested FL390 for turbulence. I asked if he could reach FL390 in 2 mins. He responded yes. Clearance was issued to climb and maintain FL390 reach in 2 mins or less to climb above aircraft X who was at FL380 opposite direction. When aircraft Y climb rate appeared to drop; I asked for a level report and aircraft Y responded; 'roger.' I then asked aircraft Y if he was level; I heard 'verifying level.'

Title: ZOB CTLR EXPERIENCED OPERROR AT FL380 WHEN ATTEMPTING TO CLB ACFT ABOVE OPPOSITE DIRECTION TFC.
Narrative: ACFT Y REQUESTED FL390 FOR TURB. I ASKED IF HE COULD REACH FL390 IN 2 MINS. HE RESPONDED YES. CLRNC WAS ISSUED TO CLB AND MAINTAIN FL390 REACH IN 2 MINS OR LESS TO CLB ABOVE ACFT X WHO WAS AT FL380 OPPOSITE DIRECTION. WHEN ACFT Y CLB RATE APPEARED TO DROP; I ASKED FOR A LEVEL RPT AND ACFT Y RESPONDED; 'ROGER.' I THEN ASKED ACFT Y IF HE WAS LEVEL; I HEARD 'VERIFYING LEVEL.'
