RHBA-2019:0665 - Bug Fix Advisory

Topic

Updated gluster-block and tcmu-runner packages that fix several bugs are now available for Red Hat OpenShift Container Storage 3.11 Batch 2 Update.

Description

gluster-block is a distributed management framework for block devices, provided as a command line utility. It aims to make Gluster-backed block storage creation and maintenance as simple as possible. gluster-block 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 tcmu-runner packages provide a service that handles the complexity of the LIO kernel target's userspace passthrough interface (TCMU). It presents a C plugin API for extension modules that handle SCSI requests in ways not possible or suitable to be handled by LIO's in-kernel backstore.

Block storage allows the creation of high-performance individual storage units. Unlike the traditional file storage capability that glusterfs supports, each storage volume/block device can be treated as an independent disk drive, so that each storage volume/block device can support an individual file system.

Users of gluster-block and tcmu-runner are advised to upgrade to these updated packages, which fix these bugs.
