Narrative:

Climbing out through 21;000 feet; we got a master warning associated with a red 'cabin attendant pr excess cabin attendant altitude' ECAM message; and the cabin attendant altitude was right at 10;000 feet in red. We quickly donned our masks; established comm; advised ATC; and descended to 10;000 feet; which ATC did clear us to as quick as we asked for it. Following the ECAM actions and QRH procedures; the cabin attendant altitude did not get to 14;0000 feet which would have dropped the masks; and the ECAM directed backup to manually deploy them. We elected to divert to ZZZ which was 90 miles off the nose. This jet had pack/pressure write ups on four previous occasions in the last ten days. The first officer did a great job. Flight attendants said the passengers only noticed the descent; cooperated fully; and that no one (passengers or crew) experienced any adverse effects. We landed uneventfully; had paramedics meet us at the gate; and no one sought medical attention. Maintenance took the jet out of service after quit a bit of trouble shooting. This older 321 had some kind of recurring pack/pressure issue.
