Stored as `results/scoutfs.tap`, this file contains TAP format 14 generated test results. Embedded in the output are some metadata so that these files can be aggregated and stored in an unique and deduplicating way, but using a generated UUID at the start of testing. The file itself also catches git ID, date, and kernel version, as well as the (possibly altered) test sequence used. Any test that has diff or dmesg output will be considered failed, and a copy of the relevant data is included as comments. 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
