xfs: catch bad stripe alignment configurations When stripe alignments are invalid, data alignment algorithms in the allocator may not work correctly. Ensure we catch superblocks with invalid stripe alignment setups at mount time. These data alignment mismatches are now detected at mount time like this: XFS (loop0): SB stripe unit sanity check failed XFS (loop0): Metadata corruption detected at xfs_sb_read_verify+0xab/0x110, xfs_sb block 0xffffffffffffffff XFS (loop0): Unmount and run xfs_repair XFS (loop0): First 128 bytes of corrupted metadata buffer: 0000000091c2de02: 58 46 53 42 00 00 10 00 00 00 00 00 00 00 10 00 XFSB............ 0000000023bff869: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 00000000cdd8c893: 17 32 37 15 ff ca 46 3d 9a 17 d3 33 04 b5 f1 a2 .27...F=...3.... 000000009fd2844f: 00 00 00 00 00 00 00 04 00 00 00 00 00 00 06 d0 ................ 0000000088e9b0bb: 00 00 00 00 00 00 06 d1 00 00 00 00 00 00 06 d2 ................ 00000000ff233a20: 00 00 00 01 00 00 10 00 00 00 00 01 00 00 00 00 ................ 000000009db0ac8b: 00 00 03 60 e1 34 02 00 08 00 00 02 00 00 00 00 ...`.4.......... 00000000f7022460: 00 00 00 00 00 00 00 00 0c 09 0b 01 0c 00 00 19 ................
