Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated device-mapper-multipath packages that fix multiple bugs are now
available.
Description
The device-mapper-multipath packages provide tools to manage multipath devices
by giving the "dm-multipath" kernel module instructions on what to do, as well
as by managing the creation and removal of partitions for Device-Mapper devices.
This update fixes the following bugs:
- due to the inability of multipathd (a path monitoring daemon) to distinguish
between deleted and recently added but not yet fully initialized devices, it
used to take more than a minute to remove a dead path and reload the device with
a new one. This has been fixed and multipathd now removes the deleted devices
immediately. (BZ#603616)
- previously, to resize a multipath device, users had to run the command
"multipathd -k'resize map <mapname>'", as running "multipath" instead caused the
multipath to become stuck in the SUSPENDED state. In this state, all
input/output to the device hung. Now users can resize the device with either
command, and the multipath device will no longer get stuck in the SUSPENDED
state. (BZ#607487)
- adding and removing a path in quick succession could have caused it to be
removed while the multipathd was still using it, which used to lead to a
segmentation fault. This has been resolved, and multipathd no longer crashes
when the path is added and quickly removed again. (BZ#607911)
Users are advised to upgrade to these updated device-mapper-multipath packages,
which resolve these issues.
