Scoutfs has supported posix ACLs through the xattr handler table, which allowed NFS to fetch them through this sideband, which worked for older kernels. With recent changes we've pulled in .get_acl because the mainline kernel is changing how ACL ops are called. But we still left .set_acl unreachable. This meant that on el9.7 nfs clients could now reach .get_acl, but still not set them. With this change, we're finally exposing .set_acl consistently across all el releases and allowing nfs clients to both get and set posix ACLs. 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
