MMFS_GENERIC

This topic describes MMFS_GENERIC error logs available in IBM Spectrum Scale™.

The MMFS_GENERIC error log entry means that GPFS™ self diagnostics have detected an internal error, or that additional information is being provided with an MMFS_SYSTEM_UNMOUNT report. If the record is associated with an MMFS_SYSTEM_UNMOUNT report, the event code fields in the records will be the same. The error code and return code fields might describe the error. See Messages for a listing of codes generated by GPFS.

If the error is generated by the self diagnostic routines, service personnel should interpret the return and error code fields since the use of these fields varies by the specific error. Errors caused by the self checking logic will result in the shutdown of GPFS on this node.

MMFS_GENERIC errors can result from an inability to reach a critical disk resource. These errors might look different depending on the specific disk resource that has become unavailable, like logs and allocation maps. This type of error will usually be associated with other error indications. Other errors generated by disk subsystems, high availability components, and communications components at the same time as, or immediately preceding, the GPFS error should be pursued first because they might be the cause of these errors. MMFS_GENERIC error indications without an associated error of those types represent a GPFS problem that requires the IBM® Support Center.
