StorPool 19.1 release notes

19.1 revision 19.01.1628.1b627d0

Released: 07 Dec 2020

  • Now collecting additional configuration data in storpool_stat for additional per-host monitoring checks, includes lldpd as dependency.

  • Adds Volumecare version 1.18 that includes support for multiple sub-clusters sending to a backup location.

  • Includes improvements and and fixes in internal tools, core and services.

  • Adds compression and proxy authorization configuration support options for the monitoring collection scripts.

  • Adds the SP_MIRROR_DIR option for containerized workloads.

  • Adds support for the Micron 9300 MTFDHAL3T2TDR NVMe drive.

  • Adds compression support for monitoring data collection scripts.

19.1 revision 19.01.1548.00e5a5633

Released: 27 Nov 2020

  • Adds fix for storpool_stat for handling statistics for unnamed volumes.

  • Adds support for Samsung PM173X NVMe drives.

  • Adds fix for iSCSI re-assign targets implementation to retry on transaction reset.

  • Improves storpool_stat send performance after longer periods of no connectivity

  • Adds storpool_initidks –no-notify option for easier StorPool disk attributes changes.

  • Adds reliability improvements in the in-server disk tester implementation

  • Adds an additional iSCSI helper option to the iface-genconf tool (see 8.2.8.  iSCSI configuration)

    The main reason for the extension is a planned change in the monitoring system to periodically check if the portal group and portal addresses exposed by the storpool_iscsi controller services are still reachable. This change will require adding OS/kernel interfaces for each of the portal groups, so that they could be used as a source IP endpoint for the periodic monitoring checks.

  • Adds fix for disk not getting ejected by the server after a drive was re-balanced out.

  • Adds workaround for a bug in the i40e driver in CentOS6 based NICs (hardware acceleration)

19.1 revision 19.01.1511.0b533fb

Released: 28 Oct 2020

  • Adds fixes for idle service VF resets with ixgbe driver based NICs.

  • Adds fixes for volumecare tags handling with unnamed volumes.

  • Adds initial support for CentOS 8.2 installations.

  • Adds tools for setting up volume overrides for many volumes from the same parent use case. For details, see Volume overrides.

    Presently, overrides are manually added by StorPool support only in places that require them. At a later point they will be re-created periodically, so that new volume objects are included in this analysis regularly.

  • Increases the listen backlog for the storpool_mgmt and storpool_bridge services.

19.1 revision 19.01.1025.0baac06a6

Released: 04 Jun 2020

  • Added Maintenance mode

  • Support for volume creation with global IDs instead of volume names.

    StorPool now can allow the creation of a volume without a name provided, by assigning it a globally unique ID, by which it could be then referred.

    Note

    Globally-unique in this regard means world-wide global uniqueness, i.e. no two StorPool deployments can generate the same ID.

    This feature was developed to handle some race conditions and retry-type cases in orchestration systems in multi-cluster environment, which could lead to duplication and reuse of another volume. By allowing the storage system to ensure the uniqueness of volume identifiers, all these cases are solved.

  • Revert to snapshot functionality

  • NIC initialization and configuration is now non-blocking.

    Non-blocking NIC initialization and configuration allows for StorPool services to continue operating normally during hardware reconfigurations or errors. For example: link flaps, changing MTU or other NIC properties, adding/removing VFs to enable/disable hardware acceleration, and so on.

    This was developed to handle delays from hardware-related reconfiguration or initialization issues, as most NICs require resets, recreation of filters, or other tasks which take time for the NIC to process, and if just busy-waited would not allow the services to process other requests in the mean time.

    The feature works by sending requests to the NIC for specific changes and rechecking their progress periodically (between processing other tasks), or when waiting for other events to complete.

  • Availability of information for active iSCSI sessions

  • Acceleration support for virtio-net based adapters

  • Added support for global active operations list.

    StorPool has support for listing the active requests on disks and clients. With this change the functionality is expanded to be able to get all such data from other services (for example, storpool_bridge and storpool_iscsi) and to show some extra details. This is also expanded to be done with a single call for the whole cluster, greatly simplifying monitoring & debugging.

    This feature was developed to replace the latthreshold tool that showed all requests of clients and disks that were taking more than a set time to complete. The present implementation gets all required data without the need for sending a separate API call for each client/disk in the cluster.

  • storpool_initdisk now has extra validation of flags and devices

  • reuseServer implicit on a down disk in small clusters.

    This feature allows a volume to be created even if a cluster is on the minimum system requirements of three nodes, with a single disk missing from the cluster, or if one of the nodes is down at the moment.

    Before this change all attempts to create a volume in this state would have resulted in “Not enough servers or fault sets for replication 3” error for volumes with replication 3.

    With this feature enabled the volume will be created as if the volume was created with reuseServer. For details, see 12.22.6.  Reusing server on disk failure.
