RHEA-2009:0232 - Product Enhancement Advisory

标题

Updated device-mapper-multipath packages that fix several bugs and add
various enhancements are now available.

描述

The device-mapper-multipath packages provide tools to manage multipath
devices using the device-mapper multipath kernel module.

This update applies the following bug fixes:

• multipath would never flush queued IO to a multipath device, leading to

problems with removing LUNs and shutting down.

• Incorrect default device configurations were fixed for IBM DASD devices,

MSA 1000/1500/2000 and EVA 3000/4000/5000/6000/8000 controllers, the IBM
DS4100, and the DELL MD3000.

• Multiple errors in printing out messages were fixed.
• multipath devices were not being created on top of Read-Only devices.
• The tur path checker was reporting false path down events during

snapshots of a LUN.

• multipathd would hold open devices that were mounted before it started.
• kpartx wouldn't work on devices larger than 2GB.
• multipath can now set "max_fds" to "max" which is the system maximum.
• multipathd was not starting up and shutting down correctly on top of

iscsi devices.

• multipathd was using up to much memory on Itanium systems.

This update adds the following enhancements:

• multipath can now set the uid/gid/mode attributes for the device nodes

created in /dev/mapper.

• multipath now has a path prioritizer for HP MSA/HSV active/passive

storage controllers.

• Default configurations were added for the IBM S/390 FBA DASD, IBM FAStT

1722-600, IBM DS3400, IBM DS4800, IBM Netfinity, Pivot3 RAIGE, SUN/LSI 2540.

• multipathd can now do an online resize of a multipath device.

All users are advised to upgrade to these updated packages, which resolve
these issues and add these enhancements.
