Install a scoutfs `tuned` profile as a system-profile for `tuned` with recommendation hint to enable this. The goal is to provide a set of basic VM tunings that are reasonably good starting point for production deployment of scoutfs. The tunings are chosen to reflect good practices to aim for responsiveness of the scoutfs deployment. The values chosen are based on existing tuned profiles, building on throughput-performance and network-throughput as a base, and tuning VM values in the same way that latency-performance does. All of them enable the performance CPU governor. None of this enables powersave settings. Different deployments may have different performance characteristics and require further adjustment, or even a completely different profile. Signed-off-by: Auke Kok <auke.kok@versity.com>
Introduction
scoutfs is a clustered in-kernel Linux filesystem designed to support large archival systems. It features additional interfaces and metadata so that archive agents can perform their maintenance workflows without walking all the files in the namespace. Its cluster support lets deployments add nodes to satisfy archival tier bandwidth targets.
The design goal is to reach file populations in the trillions, with the archival bandwidth to match, while remaining operational and responsive.
Highlights of the design and implementation include:
- Fully consistent POSIX semantics between nodes
- Atomic transactions to maintain consistent persistent structures
- Integrated archival metadata replaces syncing to external databases
- Dynamic seperation of resources lets nodes write in parallel
- 64bit throughout; no limits on file or directory sizes or counts
- Open GPLv2 implementation
