A Rust library and collection of tools for IBM Spectrum Scale (formerly GPFS) file systems.
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:
-
An nmon integration that groups NSDs by
(fs,pool)
-tuple to be shown innmon
s 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.
-
Prometheus metrics for:
- disk availability
- disk pool size
- disk pool group I/O
- quotas
See the docs for library documentation and mmoxi help [subcommand...]
for
the CLI tools.
