Previously the bulk_create_paths test tool used the same xattr name for each category of xattrs it was creating. This created a problem where two tests got their xattrs confused with each other. The first test created a bunch of srch xattrs, failed, and didn't clean up after itself. The second test saw these search xattrs as its own and got very confused when there were far more srch xattrs than it thought it had created. This lets each test specify the srch xattr names that are created by bulk_create_paths so that tests can work with their xattrs independent of each other. 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
