Btw since this is all on LVM already, you could set up lvmcache with a small SSD-based cache volume. Even some old 60GB SSD would work wonders for performance, and with the cache policy of "writethrough" you don't have to worry about its reliability (much). -- With respect, Roman -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
