SOunds like a case of using inode32 allocator, and losing the entire inode btree (i.e. the index that tracks allocated inodes) as well as the root inode, hence there being no way to easily discover and reconstruct the directory tree at all. > Am I really screwed or there's a chance to recover the data > somehow? disaster recovery tools are your only real hope at this point. go searching for xfs_irecover as a good starting point for scraping inodes out of the corpse and hence hopefully being able to reconstruct some of the directory structure...
