Released 08 May 2023

Updated disk_init_helper to properly handle multipath enabled NVMe devices.

A single VF interface is now being created for all mlx5_core based NICs by default by the vf-genconf tool, so that a dummy interface will no longer be required for any bond-based configurations.

20.0 revision 20.0.466.2a2e26fd9

Released 21 Apr 2023

storpool_volumecare is now a highly available service running on each API node

The storpool_volumecare service is now running in high-availability mode on all nodes in the cluster with the storpool_mgmt service installed, and will process operations from the currently active management node.

For the releases until this one, the storpool_volumecare service was running only on one node in the cluster. In some cases, this resulted in the service being offline if a whole node went down, until the node returned or the service was manually migrated to a new node. This was fine, since most clusters rarely change their API nodes, thus the task for keeping the service running on one node somewhere in the cluster was a rare occurrence.

Starting with this release, the storpool_volumecare service will be automatically installed on all API nodes in the cluster, and will migrate automatically to the active API node, thus making sure the service is active at all times.

The volumecare installation module is no longer available, and the service gets installed on all nodes running the storpool_mgmt service (API). The service is kept up automatically on the presently active API node; for more information, see Address for API management).

The migration from the old configuration file is done automatically on the first start of the new version of the service. The existing configuration file will be migrated in the assigned key-value store.

For more information about this service, see VolumeCare.
The SP_BRIDGE_TEMPLATE configuration option is now superseded by the mgmtConfig backupTemplateName option (more at this part of the CLI tutorial)
The storpool_stat service now collects only specific sysctl values instead of all of them, due to some operations being triggered on reading the values of sysctls like vm.stat_refresh.
