Description

  • Although Trident does document the usage of unixPermissions in the defaults section of the backend, it's only shown with octal numeric three-digit settings.
  • Additionally, it does not appear to handle a setting with setuid bits, like 1777 or 2777 in octal, and filter these out automatically.
  • For RWO PVs, it's normal that the fsGroup definition in the POD will cause this, but these PVs are only accessible by one POD/node.
