A bit perturbing
by m.roth＠5-cent.us 15 Jul '11

15 Jul '11

I'm doing an update on a machine that does have VMs running on it, and I see a number of complaints to the effect of WARNING: /lib/modules/2.6.18-194.32.1.el5/weak-updates/kmod-kvm/kvm-intel.ko needs unknown symbol kvm_vcpu_init WARNING: /lib/modules/2.6.18-194.32.1.el5/weak-updates/kmod-kvm/kvm-intel.ko needs unknown symbol kvm_mmu_invlpg And there are a lot of them (more than I can scroll back to. Has anyone else seen this? mark

CentOS5/6 Dual Boot
by Camron W. Fox 15 Jul '11

15 Jul '11

Alle, We currently have a CentOS 5.6 x86-64 server running using about 70G of a 500GB hardware raid partition. We'd like to install 6.0 alongside this installation in a dual boot configuration. We tried to install using the "Use Free Space" installation option, but the installer did not see the 475G of unused space. Is there any good way to do this, or is it even feasible? Best Regards, Camron -- Camron W. Fox Hilo Office High Performance Computing Group Fujitsu Management Services of America, Inc. E-mail: cwfox(a)us.fujitsu.com

question on compatibility and ldd
by Jerry Geis 15 Jul '11

15 Jul '11

I have a number of programs I wrote on Centos 5 (x86_64) and for one of the programs I do ldd programX linux-vdso.so.1 => (0x00007fff2cb86000) libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003528600000) libm.so.6 => /lib64/libm.so.6 (0x0000003527e00000) libxml2.so.2 => /usr/lib64/libxml2.so.2 (0x0000003531400000) libz.so.1 => /usr/lib64/libz.so.1 (0x0000003528a00000) libc.so.6 => /lib64/libc.so.6 (0x0000003527a00000) /lib64/ld-linux-x86-64.so.2 (0x0000003527600000) libdl.so.2 => /lib64/libdl.so.2 (0x0000003528200000) On C6 I do the same thing and the numbers in (Y) might change but everything else is the same for libraries. Is it safe to assume then that if I switch to C6 and recompile my program and then put the C6 version on all my C5 systems (updates that kind of thing) that everything will be compatible and run just fine. Is that the case? Thanks, Jerry

CentOS6: installing 32bit and 64bit RPMS via the installer?
by James Pearson 15 Jul '11

15 Jul '11

Installing 64bit CentOS6 only installs x86_64 and noarch RPMS - however, I have a number of legacy 32bit apps that require a number of 32bit RPMS to be installed. Does anyone know how to get the installer to install the 32bit versions of 64bit RPMS? i.e. in the way it does for CentOS5. Thanks James Pearson

amd64_edac: probe of 0000:00:18.2 failed with error -22
by Always Learning 15 Jul '11

15 Jul '11

amd64_edac: probe of 0000:00:18.2 failed with error -22 Logwatch shows this error on several machines - laptop and desktops - all running C 5.6. It never appears on the data centre servers. I have 'googled' but can not identify what error 22 is. One German posting suggests it is related to the Error Correction Code (ECC) of RAM. http://en.wikipedia.org/wiki/ECC_memory suggests the problem may be caused by laptops and desktops without a ECC facility on their motherboards. Can one safely continue to ignore this error? Thank you. -- With best regards, Paul. England, EU.

autofs problem on CentOS6
by John Hodrien 15 Jul '11

15 Jul '11

I'm trying to use autofs with Active Directory. This works: autofs_ldap_auth.conf: <autofs_ldap_sasl_conf usetls="yes" tlsrequired="yes" authrequired="yes" clientprinc="nfs/myhost@MYDOMAIN" /> /etc/sysconfig/autofs: LDAP_URI="ldap://domaincontroller1 ldap://domaincontroller2" This also works if I replace the auth with a DIGEST-MD5 from GSSAPI (which gets used by default). Good so far. However, I don't want to explicitly list the domain controllers. Discovering them via SRV records fails to work (even though logging clearly shows it's discovered the correct records). Going via a round-robin DNS target for th LDAP_URI also fails, as I think autofs expects the server to think of itself under the round-robin name, rather than its primary name, which breaks both DIGEST and GSSAPI. Anyone got any pointers on how to make this work, or is just a bug that I should track down? jh
