SVM支持多主机共享磁盘吗？

两台服务器共同连接磁盘组（JBOD），能用SVM做到卷的共享吗？

支持！

Multi-Owner Disk Set Concepts
The storage managed by Solaris Volume Manager for Sun Cluster is grouped into
multi-owner disk sets. Multi-owner disk sets allow multiple nodes to share ownership
of a disk set and to simultaneously write to the shared disks. An instance of an
application such as Oracle9i Real Application Clusters runs on each node in the
cluster, so multi-owner disk sets provide scalability. Since each instance of the
application directly accesses the shared storage, multi-owner disk sets also enhance
the performance of the application.

如果没有安装Sun Cluster呢，还支持吗？

当然支持,我实施过,比较的简单

如果不用disk set，能行吗？
例如，JBOD有2个盘，c1t0d0和c1t1d0
c1t0d0s5与c1t1d0s5做mirror的meta设备叫d0
c1t0d0s6与c1t1d0s6做mirror的meta设备叫d1
d0和d1做文件系统后，能分别mount到两台服务器上吗？

当然要做disk set，不然两边可以同时写
