How can I prevent my filesystems on multipath devices from entering read-only mode after storage errors?

Solution Unverified - Updated -

Issue

  • I am experiencing storage-side errors which are causing my multipath-ed filesystems to become read-only due to path failure.
  • This causes that the filesystem must be unmounted and mounted again in order to recover it's read-write status, once the paths are recovered.
  • While fixing these errors, I need to prevent the filesystems from entering read-only mode.

Environment

  • Red Hat Enterprise Linux
  • device-mapper-multipath
  • Fibre Channel SAN storage
