Hi, quoting from zfs docs
"The SPA allocates blocks in a round-robin fashion from the top-level vdevs. A storage pool with multiple top-level vdevs allows the SPA to use dynamic striping to increase disk bandwidth. Since a new block may be allocated from any of the top-level vdevs, the SPA implements dynamic striping by spreading out writes across all available top-level vdevs" Now, if I need two filesystems, /protect (mirrored - 2physical) and /fast_unprot (striped - 3physical), is it correct that we end up with 2 top-level vedvs. If that is the case then from the above paragraph does it mean that blocks for either filesystem blocks can end up in any of the 5 physicals. What happens to the intended protection and performance? I am sure, I am missing some basics here. Thanks for the clarification This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
