online defragmentation not happening in Exchange 2007 SP1 with CCR Cluster... Daily we are gettting Event ID 1221 as online defragmentation has completed...but it has stopped since six days.......

Hi, Is there any database related error in event log? Is there event 3864? By default, online defragment is arranged at 1AM - 5AM every day. However if for some reasons, it is likely that online defragment against this database cannot finish in these 4 hours. Then we will get the event 3864 which say online defragment will resume the next day. When the online defragment finishes, we will get the 1221. Hope this helps. Thanks, Elvis
