Can't start Analysis Services on cluster after restoring system databases

  • Hi all,

    Last night we had a suspected network issue which caused all connections to several of our SQL servers to drop out and resulted in one cluster having a corruption of it's master database. I rebuilt and restored the master from the latest backup using SQLCMD, then also restored the latest backups of MSDB and model.

    The SQL Server and SQL Agent Services are now running fine, but the SQL Analysis services are refusing to start and I'm getting no useful messages in the error log.

    Can anyone think of anything else I need to do? This is on SQL 2008 R2...

    Thanks,

    Matt

  • Have you checked the Windows evnet logs ? Specifically the System and Application ?

  • Check the OLAP log to see if there is any info. You can find the location of the log on the advanced tab of the SSAS server in SQL Config manager

  • I've found a couple of interesting entries in the OLAP log....

  • On further investigation I've noticed that the master.vmp file is empty - it must have been wiped or corrupted when the service cut out. Do you know if there is a way to potentially recover this situation other than to reinstall SSAS? Unfortunately I know very little about SSAS....

  • Hi mg_dba 

    I have the same situation , and I remove master.vmp and restart service it is started and master.vmp rebuiled
