RHEA-2017:1281 - Product Enhancement Advisory

Topic

Updated vdsm packages that fix several bugs and add various enhancements are now available.

Description

VDSM is a management module that serves as a Red Hat Virtualization Manager agent on Red Hat Virtualization Host or Red Hat Enterprise Linux hosts.

Changes to the vdsm component:

• An incorrect storage domain procedure can create invalid storage domain lvm metadata. If the invalid storage domain lvm metadata is detected the system would fail to activate the storage domain.

A warning is now logged when an invalid storage domain is detected, without failing the activation. (BZ#1450634)

• Previously, CD ejection was performed in a forceful way, similar to using a paperclip on a physical CD-ROM drive. That could cause various issues like displaying the contents of the last inserted CD after it has been ejected, and reporting IO errors when trying to access the files.

This has now been fixed and CDs are ejected correctly, similar to pressing the button on a physical CD-ROM drive.

Please note that various errors can still occur when changing a CD while accessing it. We do not recommend changing CDs when they are being accessed. If you experience any difficulties with changing CDs, please eject the CD first and only then insert another one. (BZ#1428514)
