Hello all, I have a problem with diagnosing "CRS-1615 voting device hang" error. OS: OEL 5.6 (64-bit) DB: Oracle 11.1.0.7 Storage: IBM XIV HW: Blade server 8 cores with Hyper-Threading enabled (64 GB RAM). This is active/passive failover cluster with OCFS2 used as cluster file system. OCR and VotingDisks are placed on OCFS2 mounts. Problem occurs during "impdp" import of 700GB database from NFS. First part of an import, loading data, is done without any problem. During an index creation, after hour or two, node restarts due to the problem with availability of voting disks: "[cssd(28868)]CRS-1615:voting device hang at 50% fatal, termination in 99620 ms, disk (0//ocfs2/voting1/votingdisk)" Impdp parameter file: -- userid=xxx/yyy directory=export_dir dumpfile=exportdb_%U.dmp logfile=import.log parallel=16 exclude=statistics schemas=(..list of shemas...) exclude=DB_LINK -- Database is in noarchivelog mode with "memory_target=7621050368" parameter specified. I've noticed that utilization of the server is not significant during import. As this error is reproducible I'm trying to find how to efficiently diagnose this problem and to trace the cause. If you have any suggestions I would appreciate any help. Regards, Marko -- Marko Sutic, dipl.ing.rač. My LinkedIn Profile <http://hr.linkedin.com/in/markosutic>
