New features
Not applicable to this release.
New functionalities and improvements
The following table lists and describes the new features in HCSF since v4.0.5.19.
| Item | Description |
| WEKAPP-277968 | Incorrect read responses no longer cause unavailability When a drive returns successful yet incorrect responses while a disk fails, the cluster could fail to recover the inaccurate content of the block, which could lead to erroneous IO responses or cluster unavailability. Recovery will now occur as long as enough redundancy is available. |
| WEKAPP-302123 | Enhanced output of the weka cluster failure-domain CLI command The weka cluster failure-domain CLI command is enhanced with additional information, including details about Failure Domain, Active Drives, Total Drives, Containers, Total Containers, and Raw Capacity. Moreover, extra fields are included in verbose mode (-v), such as UID, Failed Drives, Removed Drives, Drive Processes, Total Drive Processes, Compute Processes, and Total Compute Processes." Impact: Add more information to CLI command |
| WEKAPP-321442 | Improvement: A client mounted to multiple clusters remains active during upgrade A client mounted to multiple clusters can now undergo upgrades while keeping the mounts active, eliminating the need for unmounting/remounting. Follow the upgrade procedure in the HCSF documentation for more information. |
| WEKAPP-338289 | Minimum S3 cluster size requirement update S3 cluster minimum of 3 servers is no longer a requirement. It is possible to use two servers for an S3 cluster with high availability. Without high availability, it is feasible to use one server. Using one server does not provide high availability in case of a failure and is not advised for use in production. |
Fixed issues
The following tables list and describe the fixed issues in HCSF since v4.0.5.19.
Control/API
| Item | Description |
| WEKAPP-302028 | Cluster unavailability due to duplicate IP assignments with cluster and floating IPs Setting the same IP for floating IPs and WEKA cluster IPs is prohibited. This configuration causes duplicate IP assignments, leading to cluster unavailability. |
Feature/Mounting
| Item | Description |
| WEKAPP-215857 | Duplicate mount entries Running mount -a multiple times creates duplicated wekafs mounts. |
Filesystem/RAID
| Item | Description |
| WEKAPP-338848 | Data unavailability during simultaneous disks and compute process failures Simultaneous disk and compute process failures might result in data unavailability. |
Interfaces/S3-FE
| Item | Description |
| WEKAPP-331299 | S3 MultipartUpload error code 500 When an S3 client calls the uploadObjectPart function after the upload process is completed or aborted, it may receive a 500 error code instead of the expected 404. |
Platform/Network
| Item | Description |
| WEKAPP-322009 | Unavailability in mixed networking with IB PKEYs InfiniBand PKEY verification in a mixed-networking (Ethernet and Infiniband) environment might cause data unavailability. |
| WEKAPP-325457 | Use of Infiniband PKEY A cluster set with an IB interface with PKEYs might not start. |
| WEKAPP-330000 | IOs hang in mixed network clusters when specific link types are lost In mixed network environments, if a process loses connectivity through all links of a specific type (Infiniband or Ethernet), the cluster maintains the connection to this process due to its ongoing communication through alternative link layers. However, this can lead to situations where clients dependent on the lost link layer persistently attempt to connect to the affected process because the cluster does not recognize it as disconnected. |
| WEKAPP-336715 | Driver preparation script for igb_uio may fail on certain versions of Linux Sometimes, the Linux component igb_uio doesn’t install correctly on certain Linux environments due to an unexpected output from the ‘uname’ command, leading to mount failures. |
UX/CLI
| Item | Description |
| WEKAPP-336310 | weka status output erroneously shows disconnected containers as UP The weka status command output shows incorrect container statuses. It also indicates containers disconnected from the cluster as UP. |
Known issues
