You likely won't find any distributed filesystem that performs block level replication over the network, at least not a FOSS one. These are filesystems, mind you, not distributed block device drivers. If they perform any replication to afford a level of fault tolerance, it will be at the file level, not the block level. If you want true block level replication over a network, look into DRBD. However, it is also limited to mirroring. -- Stan -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
