RHBA-2018:2986 - Bug Fix Advisory

Topic

Updated heketi packages that fix various bugs are now available for Red Hat OpenShift Container Storage 3.11.

Description

Heketi provides the Red Hat Gluster Storage volume lifecycle management. It
creates the Red Hat Gluster Storage volumes dynamically and supports
multiple Red Hat Gluster Storage clusters.

This advisory fixes the following bugs:

• When many volumes create requests were made simultaneously, heketi spawned a very large number of goroutines, which greatly increased memory consumption by heketi. Heketi is now restricted to a certain number of concurrent operations in order to prevent this issue. (BZ#1600042)
• Previously, heketi ignored pvremove and vgremove errors when a device was removed while the device remove commands were used. Attempting to add the same disk again failed because it had not been properly removed in the first place. Heketi no longer ignores pvremove and vgremove errors, ensuring that devices are removed correctly, and can be re-added to Heketi after removal. Alternatively, you can also use the "--force-forget" flag with the device remove command to ignore any errors to ensure the same device can be added back to Heketi. (BZ#1629889)

Users of Heketi are advised to upgrade to these updated packages, which
fixes these bugs and adds enhancements.
