Supported kernel versions

This package is supported on the following Linux distribution kernels:

  • Red Hat Enterprise Linux 9.3 to 9.6 and derivatives (CentOS, Rocky, Alma)
  • Red Hat Enterprise Linux 10.0 and derivatives (CentOS, Rocky, Alma)
  • SUSE Enterprise Linux 15 SP7 and above
  • Ubuntu 24 LTS with 6.8 HWE kernel to 6.17 HWE kernel (including)
  • Ubuntu 22 LTS with 6.8 HWE kernel to 6.17 HWE kernel (including)
  • Ubuntu 20 LTS with 6.8 HWE kernel to 6.17 HWE kernel (including)

Generic upstream kernel support ranges are the following:

  • Linux v6.5 to v6.17 (including)

NOTE: For older kernels and distributions, see legacy support in this page below.

When building under a NVIDIA/Mellanox OFED environment, the IB layer of OFED is targeted for NFS RDMA support.

Legacy VAST NFS version 4.0.x fallback

The source package for VAST NFS 4.5.x includes the older VAST NFS 4.0.x branch code targeting older kernels that belong to:

  • Red Hat Enterprise Linux 8.1 to 8.9, 9.3 and derivatives (CentOS, Rocky, Alma)
  • SUSE Enterprise Linux 15
  • Ubuntu 22 LTS
  • Ubuntu 20 LTS
  • Ubuntu 18 LTS

Generic upstream kernel support ranges are the following:

  • Linux v4.15 to v6.6.

NOTE: Some older distribution kernels (such as RH 8.1) may require a recent Mellanox OFED being installed, as it provides a more recent IB layer along with newer kernel APIs.

Legacy VAST NFS 3.x fallback

The source package for VAST NFS 4.5.x includes the older VAST NFS 3.x branch code targeting older kernels that belong to:

  • Red Hat Enterprise Linux 7.x and derivatives (CentOS 7.x)
  • SUSE Enterprise Linux 12

Building the 4.x source package will result in a package marked as 3.x due to the less supported functionality. It currently has less functionality than 4.x (e.g. for NFSv4.1 mounts, no remoteports-based multipath).
