    Description

      While running --big-test on Debian buildd I saw this on both amd64, arm64, loong64, ppc64 etc:

      disks.disks                              w10 [ fail ]
              Test ended at 2025-12-12 07:45:42
       
      CURRENT_TEST: disks.disks
      mysqltest: At line 3: query 'select sum(Total) >= sum(Available), sum(Total)>=sum(Used) from information_schema.disks' failed: ER_UNKNOWN_ERROR (1105): Unknown error
       
      disks.disks_notembedded                  w10 [ fail ]
              Test ended at 2025-12-12 07:45:43
       
      CURRENT_TEST: disks.disks_notembedded
      mysqltest: At line 21: query 'select sum(Total) >= sum(Available), sum(Total) >= sum(Used) from information_schema.disks' failed: ER_UNKNOWN_ERROR (1105): Unknown error

      This error is not reproducible when I run it locally in a container, nor when running on Launchpad.net. Something about the disks is specific in the Debian buildd environment. Oddly though on Launchpad.net the test log indicates that the tests ran very quickly, even with no time:

      disks.disks                              w4 [ pass ]       
      disks.disks_notembedded                  w4 [ pass ]      1
