To get an explanation for any event one can ask the system: # mmhealth event show fserrinvalid
Event Name: fserrinvalid
Event ID: 999338
Description: Unrecognized FSSTRUCT error received. Check
documentation
Cause: A filesystem corruption detected
User Action: Check error message for details and the
mmfs.log.latest log for further details. See the topic Checking and
repairing a file system in the IBM Spectrum Scale documentation:
Administering. Managing file systems. If the file system is severely
damaged, the best course of action is to follow the procedures in section:
Additional information to collect for file system corruption or
MMFS_FSSTRUCT errors
Severity: ERROR
State: DEGRADED
The event is triggered by a callback which may not fire on all nodes, that
is why only a subset of nodes have the information.
Depending on the version of scale the procedure to remove the event varies:
For newer release please use
# mmhealth event resolve
Missing arguments.
Usage:
mmhealth event resolve {EventName} [Identifier]
For older releases it is described here:
https://www.ibm.com/support/knowledgecenter/STXKQY_5.0.5/com.ibm.spectrum.scale.v5r05.doc/bl1pdg_fsstruc.htm
mmsysmonc event filesystem fsstruct_fixed <filesystem_name>

Subject: [EXTERNAL] [gpfsug-discuss] mmhealth reports fserrinvalid
errors on CNFS servers
Sent by: gpfsug-discuss-boun...@spectrumscale.org
We are seeing fserrinvalid error on couple of filesystems in Spectrum Scale
cluster. These errors are reported but mmhealth only couple of nodes
(CNFS servers) in the cluster, but mmhealth on other nodes shows no issues.
Any idea what this error means? And why its reported on CNFS servers and
not on other nodes? What need to be done to fix this issue?
sudo /usr/lpp/mmfs/bin/mmhealth node show FILESYSTEM -v
