Check the filesystem even if geometry information could not be validated. Geometry information can not be validated if only a single allocation group exists and thus we do not have a backup superblock available, or if there are two allocation groups and the two superblocks do not agree on the...

Should the primary be too corrupted to be useful in locating the secondary superblocks, the program scans the filesystem until it finds and validates some secondary superblocks. At that point, it generates a primary superblock. Quotas If quotas are in use, it is possible that xfs_repair will ...
unable to verify superblock, continuing... The primary superblock is not good, and it's trying to find a valid secondary superblock. Doesn't sound promising so far - reapir can't start until a valid superblok is found... Can you dump the first sector of the device the fielsystem is ...
ates a primary superblock. Quotas If quotas are in use, it is possible that xfs_repair will clear some or all of the filesystem quota information. If so, the program issues a warning just before it terminates. If all quota information is lost, quotas are dis- ...
