mmoxi

A Rust library and collection of tools for IBM Spectrum Scale (formerly GPFS) file systems.

Motivation

The Rust library at the moment is mostly mm* -Y parsing for easier access in tooling. We did all the mm* -Y parsing and tooling in shell scripts before. You can certainly do this, but writing good tooling in bash just doesn't scale. Having a library for access to the parsed output just makes writing tools so much easier.

Notable exceptions to parsing in the library and listing in tooling are:

  1. An nmon integration that groups NSDs by (fs,pool)-tuple to be shown in nmons Disk Group I/O mode:

    mmoxi cache nmon
    NMON=g nmon -s 1 -d 1024 -g '/run/mmlocal-nmon-cache'
    

    This gives a better view of file servers and how much I/O they do with NSD groups rather than individual NSDs or everything summed up.

  2. Prometheus metrics for:

    • disk availability
    • disk pool size
    • disk pool group I/O
    • quotas
