• Creating or using encrypted software RAID member disks (i.e.
software RAID
partitions) is not
supported. However, creating encrypted software RAID arrays (e.g.
/dev/md0
) is supported.
• The NFS default for RHEL5 is "locking". Therefore, to mount nfs shares from the %post section of
anaconda, use the
mount -o nolock,udp
command to start the locking daemon before using nfs
to mount shares.
• When installing from CD-ROM or DVD-ROM on a system with an iBFT-configured network device,
Anaconda
will not include any iBFT-configured storage devices unless networking is configured. To
enable networking for the installation, use the command
linux updates=http:// [any]
at the
installation boot prompt. Note that
[any]
can be replaced with any URL.
If your system requires a static IP configuration, use the command
linux
updates=http:// [any] ip= [IP address] netmask= [netmask] dns= [dns]
.
• When installing Red Hat Enterprise Linux 5.3 on a fully virtualized guest, do
not
use the
kernel-
xen
kernel. Using this kernel on fully virtualized guests can cause your system to hang.
If you are using an Installation Number when installing Red Hat Enterprise Linux 5.3 on a fully
virtualized guest, be sure to deselect the
Virtualization
package group during the installation.
The
Virtualization
package group option installs the
kernel-xen
kernel.
Note that paravirtualized guests are not affected by this issue. Paravirtualized guests always use the
kernel-xen
kernel.
• If you are using the Virtualized kernel when upgrading from Red Hat Enterprise Linux 5 to 5.2, you
must reboot after completing the upgrade. You should then boot the system using the updated
Virtualized kernel.
The hypervisors of Red Hat Enterprise Linux 5 and 5.2 are not ABI-compatible. If you do not boot
the system after upgrading using the updated Virtualized kernel, the upgraded Virtualization RPMs
will not match the running kernel.
• When upgrading to Red Hat Enterprise Linux 5.1 or later from Red Hat Enterprise Linux 4.6,
gcc4
may cause the upgrade to fail. As such, you should manually remove the
gcc4
package before
upgrading.
• The
firstboot
language plugin has been removed, as it does not properly and completely
reconfigure the system when a new language is selected.
• When provisioning guests during installation, the
RHN tools for guests
option will not be available.
When this occurs, the system will require an additional entitlement, separate from the entitlement
used by
dom0
.
To prevent the consumption of additional entitlements for guests, install the
rhn-
virtualization-common
package manually before attempting to register the system to Red Hat
Network.
• Installing Red Hat Enterprise Linux 5.3 on a system with multiple network interfaces and manually
specified IPv6 addresses may result in a partially incorrect networking setup. When this occurs, your
IPv6 settings will not be visible on the installed system.
To work around this, set
NETWORKING_IPV6
to
yes
in
/etc/sysconfig/network
. Then, restart
your network connection using the command
service network restart
.
