Error numbers specific to GPFS application calls when data integrity may be corrupted

If there is a possibility of the corruption of data integrity, GPFS displays specific error messages or returns them to the application.

When there is the possibility of data corruption, GPFS may report these error numbers in the operating system error log, or return them to an application:

EVALIDATE=214, Invalid checksum or other consistency check failure on disk data structure.: This indicates that internal checking has found an error in a metadata structure. The severity of the error depends on which data structure is involved. The cause of this is usually GPFS software, disk hardware or other software between GPFS and the disk. Running mmfsck should repair the error. The urgency of this depends on whether the error prevents access to some file or whether basic metadata structures are involved.
