I don't think the RAID is damaged: most distributions including Debian remove nearly all files from /tmp at boot. If /tmp and / were as you described the same filesystem your server most probably did what amounts to "rm -rf /". You would probably have got the same result with any filesystem as mounting the same filesystem at several points in the VFS is not BTRFS-specific. Unless you can restore a snapshot or there is a way to debug the filesystem to restore a previous state, I'm afraid there's nothing to be done.
