Comment 4 for bug 1814944

The problem was not reproduced during retest.

The alarm "File System threshold exceeded" was cleared after the disk usage of /opt/cgcs dropped down to 1% (its previous status).

Details:
 - Shortly after a file with 20G in size under /opt/cgcs, which is 20G in total, an alarm was triggered
      "File System threshold exceeded ; threshold 90.00%, actual 99.91%"

      host=controller-1.filesystem=/opt/cgcs

 - The offending controller became 'degraded'

 - After reduced the disk usage (by removing the 20G test file under /opt/cgcs), the alarm cleared. And the
     controller became 'available'.
