----------------------------------------------------------------------
Introduction
The following topics are covered in this document:
o Changes to the CentOS installation program
(Anaconda)
o General information
o Changes to drivers and hardware support
o Changes to packages
Changes to the CentOS Installation Program (Anaconda)
The following section includes information specific to the CentOS
installation program, Anaconda.
Note
In order to upgrade an already-installed CentOS 3 system
to Update 3, you must use yum to update those packages that
have changed. The use of Anaconda to upgrade to Update 3 is not supported.
Use Anaconda only to perform a fresh install of CentOS 3
Update 3.
o If you are copying the contents of the CentOS 3
Update 3 CD-ROMs (in preparation for a network-based installation, for
example) be sure you copy the CD-ROMs for the operating system only.
Do not copy the Extras CD-ROM, or any of the layered product CD-ROMs,
as this will overwrite files necessary for Anaconda's proper
operation.
These CD-ROMs must be installed after CentOS has
been installed.
General Information
This section contains general information not specific to any other
section of this document.
o CentOS 3.3 adds the most recent version of
the KornShell (ksh) to the CentOS Extras CD.
KornShell is a shell programming language for both interactive and
shell script use, and is upward compatible with the Bourne Shell (sh).
The new ksh package is an optional alternative to pdksh, which is
already included in the core distribution. It is useful in
circumstances where precise compatibility with AT&T ksh semantics is
required.
o The autofs package, which controls the operation of the automount
daemons running on CentOS, has been updated to
version 4. This update provides full backward compatibility with
version 3. Additionally, it adds the following features:
o Browsable mounts (ghosting) -- Ghosting of map directories allows
you to see the directories in the autofs map without mounting
them. When they are accessed (such as when a directory listing is
requested) the map entry is mounted so that it is seen.
o Replicated Server support -- Replicated server functionality
allows the administrator to specify map entries that point to
multiple, replicated servers. The automount daemon attempts to
determine the best server to use for mounts by testing the
latency of an rpc_ping to each available server. Weights may also
be assigned to the servers, allowing for more administrator
control. Refer to the
/usr/share/doc/autofs-4.1.3/README.replicated-server file for
additional map format information.
o Executable maps -- A map can now be marked as executable. The
initscript that parses the auto.master map passes this as a
program map to the auto-mounter. A program map is called as a
script with the key as an argument. It may return no lines of
output if there is an error, or one or more lines containing a
map (with \ quoting line breaks). This feature is useful for
implementing /net functionality.
o Multi-mounts -- This feature allows the automount daemon to seek
multiple lookup methods in succession. For example, a lookup
could query NIS and file maps.
o The version of the httpd Web server included as part of CentOS
3 Update 3 includes several significant changes:
o The mod_cgi module has been enhanced to correctly handle
concurrent output on stderr and stdout
o SSL environment variables defined by mod_ssl can be used directly
from mod_rewrite using the %{SSL:...} syntax. For example,
"%{SSL:SSL_CIPHER_USEKEYSIZE}" may expand to "128".
Similarly, SSL environment variables can be used directly from
mod_headers using the %{...}s syntax.
o The mod_ext_filter module is now included
o The minimal acceptable group id that will be used by suexec has
been lowered from 500 to 100. This allows the use of suexec with
users belonging to the "users" group.
o CentOS 3.3 includes a new disk dump facility
that can serve as an alternative to, (or in addition to) the CentOS
netdump facility.
When the disk dump facility is configured and enabled, upon a system
crash, the contents of memory will be written to the configured disk
location. Upon reboot, the data will be copied from the configured
disk location and formatted into a vmcore file. This file is identical
in nature to files created by the netdump facility, and is stored in a
unique subdirectory of /var/crash/. The vmcore file may then be
analyzed using the crash(8) utility.
Currently, only x86- or IA64-based systems with SCSI subsystems that
use the aic7xxx, aic79xx, or MPT Fusion drivers are supported. In
addition, the disk dump facility requires the dedication of a disk
device or partition large enough to contain all of physical memory.
This disk space must be configured and preformatted before use. After
doing so, the disk dump facility can then be enabled using chkconfig,
and the service started.
The kernel modules required for the disk dump facility are included
with the CentOS 3.3 kernel. The associated
user-space package is named diskdumputils and, like the netdump
user-space package, is installed by default.
For more information, refer to the following resources:
o /usr/share/doc/diskdumputils-0.4.0-0/README
o diskdumpfmt(8) man page
o diskdumpctl(8) man page
o savecore(8) man page
Changes to Drivers and Hardware Support
This update includes bug fixes for a number of drivers. The more
significant driver updates are listed below. In some cases, the original
driver has been preserved under a different name, and is available as a
non-default alternative for organizations that wish to migrate their
driver configuration to the latest versions at a later time.
Note
The migration to the latest drivers should be completed before the next
CentOS update is applied, because in most cases only one
older-revision driver will be preserved for each update.
These release notes also indicate which older-revision drivers have been
removed from this kernel update. These drivers have the base driver name
with the revision digits appended; for example, megaraid_2002.o. You must
remove these drivers from /etc/modules.conf before installing this kernel
update.
Keep in mind that the only definitive way to determine what drivers are
being used is to review the contents of /etc/modules.conf. Use of the
lsmod command is not a substitute for examining this file.
Adaptec RAID (aacraid driver)
o The aacraid driver has been updated from 1.1.2 to 1.1.5-2339
o The new driver is scsi/aacraid/aacraid.o
o The older driver has been preserved as
addon/aacraid_10102/aacraid_10102.o
LSI Logic RAID (megaraid driver)
Note
The megaraid2 driver includes support for a number of new host bus
adapters (certain PERC4 and Serial ATA products) that are not supported by
the megaraid driver. If your system contains these newer products
exclusively, the megaraid2 driver is loaded by default. If you have the
older products exclusively, the megaraid driver will continue to be the
default.
However, if you have a mix of old and new MegaRAID adapters, then the
driver that is selected depends on the order in which the adapters are
scanned. (Note that you cannot have both the megaraid and megaraid2
drivers loaded at the same time.) If the default driver on your system is
not the desired one, take one of the following actions:
o If you are installing the system, type the following command at the
boot prompt:
expert noprobe
Next, select the desired driver from the subsequent menu.
o If the system is already installed, edit /etc/modules.conf and change
the "alias scsi_hostadapter" lines referring to the megaraid or the
megaraid2 driver to the desired driver. Note that after making any
changes to /etc/modules.conf you must rebuild the initrd image; refer
to the mkinitrd man page for further details.
o The megaraid2 driver has been updated from v2.10.1.1 to v2.10.6-RH1
o The new driver is scsi/megaraid2.o
o The older driver has been preserved as
addon/megaraid_2101/megaraid2101.o
o The v2.00.9 driver has been removed
o The default driver remains the v1.18k driver (megaraid.o)
IBM ServeRAID (ips driver)
o The ips driver has been updated from 6.11.07 to 7.00.15
o The new driver is scsi/ips.o
o The older driver has been preserved as addon/ips_61107/ips_61107.o
o The ips 6.10.52 driver (ips_61052.o) has been removed
LSI Logic MPT Fusion (mpt* drivers)
o These drivers have been updated from 2.05.11.03 to 2.05.16
o The new drivers are located in message/fusion/
o The older drivers have been preserved in addon/fusion_20511
o The 2.05.05+ drivers (mpt*_20505.o) have been removed
Compaq SA53xx Controllers (cciss driver)
o The cciss driver has been updated from 2.4.50.RH1 to v2.4.52.RH1
QLogic Fibre Channel (qla2xxx driver)
o These drivers have been updated from 6.07.02-RH2 to 7.00.03-RH1
o The new drivers are located in addon/qla2200
o The older driver has been preserved in addon/qla2200_60702RH2
o The 6.06.00b11 drivers (qla2*00_60600b11.o) have been removed
Note
The QLA2100 adapter has been retired by QLogic. This adapter is no longer
supported by QLogic. Therefore, the driver is located in the
kernel-unsupported package.
Emulex Fibre Channel (lpfc driver)
o This driver has been added to the distribution. The version is 7.0.3
o The driver is located in addon/lpfc
Intel PRO/1000 (e1000 driver)
o This driver has been updated from 5.2.30.1-k1 to 5.2.52-k3
Intel PRO/100 (e100 driver)
o This driver has been updated from version 2.3.30-k1 to 2.3.43-k1
Broadcom Tigon3 (tg3 driver)
o This driver has been updated from v3.1 to v3.6RH
