            From Minh:
            ERROR often caused by out of inode on the mdt
            SHORT often means there isn't enough files to generate enough data to collect between 1 second

            Minh, can you explain the SHORT messages?

            I often see SHORT and ERROR in the output of my mds-survey run. This needs to be explained in the doc too.
