The xfstests's golden output includes the full set of tests we expect to run when no args are specified. If we specify args then the set of tests can change and the test will always fail when they do. This fixes that by having the test check the set of tests itself, rather than relying on golden output. If args are specified then our xfstest only fails if any of the executed xfstest tests failed. Without args, we perform the same scraping of the check output and compare it against the expected results ourself. It would have been a bit much to put that large file inline in the test file, so we add a dir of per-test files in revision control. We can also put the list of exclusions there. We can also clean up the output redirection helper functions to make them more clear. After xfstests has executed we want to redirect output back to the compared output so that we can catch any unexpected output. Signed-off-by: Zach Brown <zab@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
