But it does allow to specify to have different replication/stripping policies for metadata and data. Such has: configure a raid0 with N drives, but mirror the metadata across all of them. >> Do y'all foresee btrfs being used in exabtye installations? >> Does/Will btrfs have RAID awareness in that it will align "the >> superblock and metadata to the RAID stripe"? This is a feature that is intented to provided in the future, this was talked about in the [EMAIL PROTECTED] irc channel. There isn't code for this currently. -- Miguel Sousa Filipe -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
