NFS

GlusterFS

  • The following kernel modules must be loaded:

    1. dm_snapshot
    2. dm_mirror
    3. dm_thin_pool

    For kernel modules, lsmod | grep <name> will show you if a given module is present, and modprobe <name> will load a given module.

  • Each node requires that the mount.glusterfs command is available.

  • GlusterFS client version installed on nodes should be as close as possible to the version of the server.

  • Take glusterfs 7.x as an example.
