As a user, I'm not sure what can I expect from the restore command. From where does it restore? Eg. a file? As a tester I have use for a temporary clearing of a superblock on a device, then mount it with -o degraded, work work, and then undo clearing. So, my idea is like btrfs device zero-superblock --undo with the obvious sanity checks. A regular user would never need to call this. david -- 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
