RHEA-2018:0642 - Product Enhancement Advisory

Topic

Updated rhgs-gluster-block-prov-container image is now available in the Red Hat Container Registry.

Description

Gluster-block provisioner is a distributed management framework for block devices, provided as a command line utility. It aims to make block interface backed persistent volume creation and maintenance as simple as possible. gluster-block provisioner can provision block devices and export them as iSCSI LUNs across multiple nodes and uses iSCSI protocol for data transfer as SCSI block/commands.

• The rhgs-gluster-block-prov-container packages have been upgraded to the latest version of Red Hat Gluster Storage which provides a number of bug fixes and enhancements over the previous version.(BZ#1535932)
• Previously, the gluster-block provisioner did not identify the storage units correctly in the PVC. For example, it would identify 1 as 1GiB by default and the provisioner would fail on 1Gi. With this enhancement, gluster-block provisioner identifies the storage units correctly, ie, 1 will be treated as 1 byte, 1Gi will be treated as 1 GibiByte, and 1Ki will be treated as 1KibiByte. (BZ#1505290)

All users of rhgs-gluster-block-prov-container image are advised to pull this updated image from the Red Hat Container Registry.
