The issue with the previous attempt to fix the orphan-inodes test was that we would regularly exceed the 120s timeout value put in there. Instead, in this commit, we change the code to add a new counter to indicate orphan deletion progress. When orphan inodes are deleted, the increment of this counter indicates progress happened. Inversely, every time the counter doesn't increment, and the orphan scan attempts counter increments, we know that there was no more work to be done. For safety, we wait until 2 consecutive scan attempts were made without forward progress in the test case. 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
