The `-R` option will shuffle the order in which tests are executed. The testing order shouldn't affect the outcome of any of the tests, but in practice many of these tests will execute code slightly different based on the history of the filesystem, resources allocated, memory usage etc. of tests that were executed before. Shuffling the order of tests therefore introduces small semi-random variations in the enviroment. The xfstests test is the only one that can't be shuffled yet into the mix, so it is kept at the end. This is because it leaves the filesystems unmounted. At a later point we may want to address this. 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
