The current test sequence performs the unlink and immediately tests whether enough resources are available to create new files again, and this consistently fails. One of my crummy VMs takes a good 12 seconds before the `touch` actually succeeds. We care about the filesystem eventually returning from ENOSPC, and certainly we don't want it to take forever, but there is a period after our first ENOSPC error and cleanup that we expect ENOSPC to fail for a bit longer. Make the timeout 120s. As soon as the `touch` completes, exit the wait loop. 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
