Host aggregates and placement aggregates

Hi All, We have a yoga OSA setup. We have upgraded the setup from Xena to Yoga. We have found that some of the host aggregates have not synced to the placement aggregates. As a result , the vm creation on those aggregate nodes is failing even though they have the full capacity. I have tried the placement sync aggregates command but it did not help. Is this a known bug in Yoga ? Thanks Y.G
