Project Description

Overall: Existing NFS-HA Consulting solution exists (for SLES15 SP1 and SP2+) and is in production at customers. Goal is to improve this solution, enhance the documentation and make it more robust.

Goal for this Hackweek

  • Rewrite and cleanup existing documentation of this solution in ASCII-DOC
  • Test with SLES15 SP4 and new NFS Kernel server features introduced (unshare/hostname, NFS v4, NFSV4LEASETIME etc.)
  • make sure "waitforleasetimeonstop" is NOT set to true on the exportfs primitive
  • Add nfsdcltrack handling
  • Use NFS exports from /etc/exports instead of ocf:heartbeat:exportfs (should make CIB simpler)

Resources

  • Bug 1203746 - SLES15-SP4 60s NFS timeout during cluster failover | _nfs4reclaimopenstate: Lock reclaim failed!
  • https://bugzilla.suse.com/show_bug.cgi?id=1201271

    Description

    As the user-space NFS provider, the NFS-Ganesha is wieldy use with serval projects. e.g. Longhorn/Rook. We want to create the Kubernetes Controller to make configuring NFS-Ganesha easy. This controller will let users configure NFS-Ganesha through different backends like VFS/CephFS.

    Goals

    1. Create NFS-Ganesha Package on OBS: nfs-ganesha5, nfs-ganesha6
    2. Create NFS-Ganesha Container Image on OBS: Image
    3. Create a Kubernetes controller for NFS-Ganesha and support the VFS configuration on demand. Mammuthus

    SUSE Health Check Tools by roseswe

    SUSE HC Tools Overview

    A collection of tools written in Bash or Go 1.24++ to make life easier with handling of a bunch of tar.xz balls created by supportconfig.

    Background: For SUSE HC we receive a bunch of supportconfig tar balls to check them for misconfiguration, areas for improvement or future changes.

    Main focus on these HC are High Availability (pacemaker), SLES itself and SAP workloads, esp. around the SUSE best practices.

    Goals

    • Overall improvement of the tools
    • Adding new collectors
    • Add support for SLES16
