What's in this release

What's new

  • Supports the HDFS protocol, allowing components within the Hadoop ecosystem to access and use file systems.

  • Supports custom export paths for NFS protocol file systems.

  • Supports adding compute resources to file controllers.

  • Supports the file management network and the file access network sharing the same VM network, with their IP addresses in the same network segment.

  • Supports displaying active client connections of file systems.

  • Provides performance monitoring charts for file storage clusters and file systems.

  • Supports configuring whether Windows clients can access file storage clusters via the NFSv3 protocol on AOC.

  • Supports automatic restart of file controllers if their system disks enter read-only mode.

  • Supports prefetching files.

Improvements

  • Sets the metadata disk redundancy policy for the newly created file system to 3 replicas, which improves metadata performance and enhances metadata security.

  • Reduces I/O pause duration during file controller online/offline operations and high-availability (HA) failovers.

  • Optimizes the cluster upgrade process to eliminate the need to restart file controllers, further reducing I/O pause duration during upgrades.

  • Refines the mechanism for adding the file controller's file management IP to the AOC allowlist.

  • Optimizes the storage engine's block allocation mechanism to improve block reclamation efficiency.

Resolved issues

  • The file management virtual IP (VIP) failed to migrate automatically when the file management network was abnormal. The issue has been resolved by improving the VIP high-availability mechanism.

  • Leaked socket file descriptors in the NTIRPC component caused NFS requests to be unprocessed. The issue has been resolved in this release.

  • The NFS backend returned unexpected non-retryable error codes under specific conditions. The issue has been resolved in this release.

  • The sfs-agent restarted sfs-meta, sfs-data, or sfs-ganesha during a coredump, which interrupted the process. The issue has been resolved in this release.
