Updated dmraid packages that fix multiple bugs are now available for Red Hat Enterprise Linux 6.
The dmraid packages provide the ATARAID/DDF1 activation tool. The tool supports RAID device discovery and RAID set activation. It also displays properties for ATARAID/DDF1-formatted RAID sets on Linux kernels using the device-mapper utility.
- Prior to this update, a grub installation failed silently on a dmraid mirror because the device geometry of RAID sets was not set properly. Consequently, the set partition's MBR failed to be created and the partition failed to boot. With this update, the underlying code has been modified and the geometry on dmraid devices is set up correctly.
- The dmraid binary was compiled without gcc's -g option and the debuginfo file did not contain the ".debug_info" section. Consequently, it was not possible to generate debugging information and debug dmraid properly. With this update, the binary has been compiled with the proper debugging options and the problem no longer occurs.
- When the dmraid tool was accessing a 4 KB sector or smaller, it returned a misleading error message. With this update, the library function that checks the device size has been modified and the error message is no longer displayed under these circumstances.
All users of dmraid are advised to upgrade to these updated packages, which fix these bug.
