Is DRBD supported on RHEL systems?

Updated 2014-08-07T11:11:05+00:00

Issue

  • The upstream kernel includes support for Distributed Replicated Block Device (DRBD) starting with the kernel version 2.6.33. Do RHEL kernels include DRBD?
  • Is DRBD supported on Red Hat Enterprise Linux ?
  • Can I use DRBD block devices in a High Availability or Resilient Storage cluster?

Environment

  • Red Hat Enterprise Linux (RHEL), 5, 6, or 7
    • Optionally with the High Availability and/or Resilient Storage Add On
  • DRBD

Resolution

LINBIT is a Red Hat partner, and provides support directly for DRBD. LINBIT has tested and certified their DRBD product to run on RHEL 5 Update 6 and later, RHEL 6, and RHEL 7.
