RHBA-2014:1409 - device-mapper-persistent-data bug fix and enhancement update
Synopsis
device-mapper-persistent-data bug fix and enhancement update
Type/Severity
Bug Fix Advisory (none)
Topic
Updated device-mapper-persistent-data packages that fix one bug and add two enhancements are now available.
Description
The device-mapper-persistent-data packages provide device-mapper thin provisioning (thinp) tools.
This update adds thin provisioning tools to support the dm-cache, as well as the dm-era functionality for change tracking to the device-mapper-persistent-data packages in Red Hat Enterprise Linux 6 as a Technology Preview. (BZ#1038236, BZ#1084081)
More information about Red Hat Technology Previews is available here: https://access.redhat.com/support/offerings/techpreview/
In addition, this update fixes the following bug:
- The thin_dump utility as well as other persistent-data tools supported only 512 B block sizes on accessed devices. Consequently, persistent-data tools could perform I/O to misaligned buffers. The underlying source code has been updated to support 4 KB block size, thus fixing this bug. (BZ#1035990)
Users of device-mapper-persistent-data are advised to upgrade to these updated packages, which fix this bug and add these enhancements.
