4. Known Issues

In some circumstances, disks that contain a whole disk format (e.g. a LVM Physical Volume populating a whole disk) are not cleared correctly using the clearpart --initlabel kickstart command. Adding the --all switch — as in clearpart --initlabel --all — ensures disks are cleared correctly.

During the installation on POWER systems, the error messages similar to:

attempt to access beyond end of device
loop0: rw=0, want=248626, limit=248624

may be returned to sys.log. The errors do not prevent installation and only occur during initial setup. The filesystem created by the installer will function correctly.

When installing on the IBM System z architecture, if the installation is being performed over SSH, avoid resizing the terminal window containing the SSH session. If the terminal window is resized during installation, the installer will exit and installation will terminate.

The kernel image provided on the CD/DVD is too large for Open Firmware. Consequently, on the POWER architecture, directly booting the kernel image over a network from the CD/DVD is not possible. Instead, use yaboot to boot from a network.

The anaconda partition editing interface includes a button labeled Resize. This feature is intended for users wishing to shrink an existing filesystem and underlying volume to make room for installation of the new system. Users performing manual partitioning cannot use the Resize button to change sizes of partitions as they create them. If you determine a partition needs to be larger than you initially created it, you must delete the first one in the partitioning editor and create a new one with the larger size.

Channel IDs(read, write, data) for network devices are required for defining and configuring network devices on s390 systems. However, system-config-kickstart — the graphical user interface for generating a kickstart configuration — cannot define channel IDs for a network device. To work around this issue, manually edit the kickstart configuration that system-config-kickstart generates to include the desired network devices.
