AIX – statvfs() failed with errno 52

I stumbled accross this errormessage searching for a bug in a SNMP configuration.

You will find entries like these in /var/tmp/muxatmd.log taht statvfs() failed.SNMP was not able to check the memory usage of a system. It hung after “hrDevices.Storage.NUMBER”. Identifying the number I noticed that a mountpoint should be next.
Doing a mount and a “ls -l” in rootfilesystem showed me that a mountpoint was still mounted, but not accessable for the system. Therefore the statvfs failed, as it could not access the mount.
With removing this mountpoint you can get rid of the errormessage.
