We want to enable the test case for: generic/023 - tests that renameat2 syscall exists generic/024 - renameat2 with NOREPLACE flag Move both generic/025 and 078 to the no run list so that we can test the unsupported output if the flags were passed that were not supported. Example output: generic/025 [not run] fs doesn't support RENAME_EXCHANGE generic/078 [not run] fs doesn't support RENAME_WHITEOUT Signed-off-by: Bryant G. Duffy-Ly <bduffyly@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
