• Using the
swap --grow
parameter in a kickstart file without setting the
--maxsize
parameter at
the same time makes anaconda impose a restriction on the maximum size of the swap partition. It
does not allow it to grow to fill the device.
For systems with less than 2GB of physical memory, the imposed limit is twice the amount of
physical memory. For systems with more than 2GB, the imposed limit is the size of physical memory
plus 2GB.
• The
gfs2_convert
program may not free up all blocks from the GFS metadata that are no longer
used under GFS2. These unused metadata blocks will be discovered and freed the next time
gfs2_fsck is run on the file system. It is recommended that
gfs2_fsck
be run after the filesystem
has been converted to free the unused blocks. These unused blocks will be flagged by gfs2_fsck
with messages such as:
Ondisk and fsck bitmaps differ at block 137 (0x89)
Ondisk status is 1 (Data) but FSCK thinks it should be 0 (Free)
Metadata type is 0 (free)
These messages do not indicate corruption in the GFS2 file system, they indicate blocks that should
have been freed, but were not. The number of blocks needing to be freed will vary depending on the
size of the file system and block size. Many file systems will not encounter this issue at all. Large file
systems may have a small number of blocks (typically less than 100).

• When running the bare-metal (non-Virtualized) kernel, the X server may not be able to retrieve
EDID
information from the monitor. When this occurs, the graphics driver will be unable to display
resolutions highers than 800x600.
To work around this, add the following line to the
ServerLayout
section of
/etc/X11/
xorg.conf
:
Option "Int10Backend" "x86emu"
