# yum update
You will also see this error if you downgrade glibc to an earlier version on an installed 5.3 system.
•
mvapich
and
mvapich2
in Red Hat Enterprise Linux 5 are compiled to support only
InfiniBand/
iWARP
interconnects. Consequently, they will not run over ethernet or other network interconnects.
• On systems with more than two encrypted block devices, anaconda has a option to provide a
global passphrase. The init scripts, however, do not support this feature. When booting the system,
entering each individual passphrase for all encrypted devices will be required.
• When upgrading openmpi using yum, the following warning may be returned:
cannot open `/tmp/openmpi-upgrade-version.*' for reading: No such file or
directory
The message is harmless and can be safely ignored.
• Configuring IRQ SMP affinity has no effect on some devices that use message signalled interrupts
(MSI) with no MSI per-vector masking capability. Examples of such devices include
Broadcom
NetXtreme
Ethernet devices that use the
bnx2
driver.
If you need to configure IRQ affinity for such a device, disable MSI by creating a file in
/etc/
modprobe.d/
containing the following line:
options bnx2 disable_msi=1
Alternatively, you can disable MSI completely using the kernel boot parameter
pci=nomsi
.
• A bug in the updated
/etc/udev/rules.d/50-udev.rules
file prevents the creation of
persistent names for tape devices with numbers higher than 9 in their names. For example, a
persistent name will not be created for a tape device with a name of
nst12
.
To work around this, add an asterisk (*) after each occurrence of the string
nst[0-9]
in
/etc/
udev/rules.d/50-udev.rules
.
• The
smartctl
tool cannot properly read SMART parameters from SATA devices.
• A bug in previous versions of
openmpi
and
lam
may prevent you from upgrading these packages.
This bug manifests in the following error (when attempting to upgrade
openmpi
or
lam
:
error: %preun(openmpi- [version] ) scriptlet failed, exit status 2
As such, you need to manually remove older versions of
openmpi
and
lam
in order to install their
latest versions. To do so, use the following
rpm
command:
rpm -qa | grep '^openmpi-\|^lam-' | xargs rpm -e --noscripts --allmatches
• When using
dm-multipath
, if
features "1 queue_if_no_path"
is specified in
/etc/
multipath.conf
then any process that issues I/O will hang until one or more paths are restored.
