How are you managing the failover? If you are doing failover of the file system (e.g., via SAN), then I'd expect the HA service manager (rgmanager, pacemaker, etc.) to handle the export, since you don't want to do the export until the file system is mounted. If you are exporting a replica file system, then I believe it has to be a block level replica (e.g., DRDB)--a file system replica via rsync or such will have different inode numbers, and AIR the inode number shows up in the NFS file handle. If you're doing something different, you'll need to give us details. -dan -- Linux-cluster mailing list Linux-cluster@redhat.com https://www.redhat.com/mailman/listinfo/linux-cluster
