RHBA-2018:1983 - Bug Fix Advisory

Topic

Updated kmod-kvdo packages that fix one bug are now available for Red Hat Enterprise Linux 7.

Description

The kmod-kvdo packages provide the kernel module for Virtual Data Optimizer (VDO), which is a block virtualization technology that enables you to create compressed and deduplicated pools of block storage.

This update fixes the following bug:

• Sometimes a Universal Deduplication Service (UDS) index for a Virtual Data Optimizer (VDO) volume falls offline due to a read error on the underlying media. In this case, running the "vdo status" command to check the status of the affected VDO volume previously displayed "Index status: online" even though the index was offlined due to the read error. This update fixes the VDO source code that handles the index status. As a result, the status now correctly reads "Index status: offline" in the described scenario. (BZ#1578421)

Users of kmod-kvdo are advised to upgrade to these updated packages, which fix this bug.
