| # FS QA Test No. 388 |
| # |
| # Test XFS log recovery ordering on v5 superblock filesystems. XFS had a problem |
| # where it would incorrectly replay older modifications from the log over more |
| # recent versions of metadata due to failure to update metadata LSNs during log |
| # recovery. This could result in false positive reports of corruption during log |
| # recovery and permanent mount failure. |
| # |
| # To test this situation, run frequent shutdowns immediately after log recovery. |
| # Ensure that log recovery does not recover stale modifications and cause |
| # spurious corruption reports and/or mount failures. |
