I am considering using a Sheepdog-based KVM cluster to run a Postgres database, where data consistency is important.
Are there any problems or issues I should consider in this application? Does Sheepdog support write barriers? Should I use ext4 with journal checksumming? I notice the design doc says "The write request is successful only when all replicas can be successfully updated", so I guess fsync shouldn't return until all data has been written. But I'd be grateful for any real-world experiences with databases on KVM+Sheepdog. Thanks, Brian. -- sheepdog mailing list [email protected] http://lists.wpkg.org/mailman/listinfo/sheepdog
