MMFS_FSSTRUCT
This topic describes the MMFS_FSSTRUCT error log available in IBM
Storage Scale.
The
MMFS_FSSTRUCT error log entry indicates that GPFS has detected a problem with the on-disk structure of the
file system. The severity of these errors depends on the exact nature of the inconsistent data
structure. If it is limited to a single file, then EIO errors are reported
to the application and operation continues. If the inconsistency affects vital metadata structures,
then operation ceases on this file system. These errors are often associated with an MMFS_SYSTEM_UNMOUNT error log
entry and probably occurs on all nodes. If the error occurs on all nodes, some critical piece of the
file system is inconsistent. This can occur as a result of a GPFS error or an error in the disk system.Note: When the
mmhealth command displays an fsstruct error, the
command prompts you to run a file system check. When the problem is resolved, issue the following
command to clear the fsstruct error from the mmhealth
command. Issue the following command on a node or modes that show the
event. You must specify the file system name
twice:
mmhealth event resolve fserrinvalid <fsname>If the file system is severely damaged, then the best course of action is to follow the procedures in Additional information to collect for file system corruption or MMFS_FSSTRUCT errors, and then contact the IBM® Support Center.
