Re: [CentOS] A special kernel for linux as guest os

Dear Yagi-san, > I heard from the horse's mouth that the CentOS team is working on the > 100Hz centosplus kernel. I think your request triggered the action :-) > They want make people happy. That sounds nice! This TIPS, CONFIG_HZ=100, is one of FAQs. It will make most of us happy. Now we can get kernel-vm package on dev.centos.org. Is it a test release of the special kernel? I installed the kernel-vm. Its change-log shows HZ=100. And the kernel seems better for clock interval on VMWare. Thanks a lot. Yuji

Unable to boot xen dom0 on IBM System x3250
by Pat and Lori Boyer 28 Sep '07

28 Sep '07

I have an IBM System x 3250 that successfully boots using the standard kernel (2.6.18-8.1.10.el5) but fails to boot with the xen kernel. The kernel appears to fail when it attempts to initialize the driver for the onboard SAS controller (LSI Logic / Symbios Logic SAS1064E PCI-Express Fusion-MPT SAS). Can anyone provide any advice? Here's the relevant info. Please let me know if any other information would be helpful.

too many links error when creating directories
by chitgoks 28 Sep '07

28 Sep '07

hi , our centos os has an ext3 file system. and i cant create any more directories, it gives me a too many links error, even when doing a manual mkdir. is there any workaround for this? without changing it to a different file system like reiserFS? we dont have a reiserfs module in the os so it will have to be installed. and can it be possible to install a reiserFS without having to reformat the os? just mount it after installing? please advise

hostname not being picked up by DHCP
by Denis 28 Sep '07

28 Sep '07

Hi - I am using the CentOS v5 desktop installation and am setting up a new lab for our engineering department. Initially I computers got their IP addresses and computer names from the DHCP process and the computer were getting the info from the dynamic pool. These name would be d-23-76.mnsu.edu, where the d stood for dynamic and 23-76 refered the IP address of xx.xx.23.76. The computer hostname would show up as d-23-76. I did not want the computers to get different IP address so I put the computers onto our DHCP table as manual DHCP clients by assigning a name and mac address to an IP address. Now the computers get the correct IP address but the hostname is localhost. How can I get the correct name for hostname from DHCP? -- Denis Becker Information Technology - Engineering MN State Univ., Mankato Mankato, MN ph: 507-389-5617 fx: 507-389-5002

glibc errors related to nss_ldap or pam_ldap?
by Bjorn Oglefjorn 27 Sep '07

27 Sep '07

I am trying to track down the cause of some errors that have been occurring on a number of our servers using LDAP. We have noticed that when a certain LDAP group exceeds 65 users we begin seeing glibc errors for users in the group. Users that are not in the group do not exhibit this behavior. We have seen this issue on machines running Centos 4.5 x86 & x86_64 with glibc-2.3.4-2.36 and RH4 x86_64 running glibc-2.3.4-2.25. We are running Fedora Directory Server 1.0.4 on Centos 4.5. We have added a 3rd FDS slave and turned up debugging but have not seen anything that appears to be relevant in the logs on the 3rd slave. This problem is not a 65 user limit as we have other groups with well over 65 members that do not display this behavior. We also created a new group with identical users and it did not display this problem. 1) With 66 users in the massweb group [root@megalon ~]# getent group massweb *** glibc detected *** free(): invalid next size (normal): 0x09a225b0 *** Aborted 2) After removing any user from the massweb group to reduce the total members to 65 [root@megalon ~]# getent group massweb massweb:x:3016:afaxon,ashairza,ccrump,jhorowit,mmarum,morendai,usmall,adroffne,afaxon,amurphre,aoliver,ayellipe,bdonohue,bdunn,beckert,blarsen,bwphilli,catanis,ccrump,chaynes,clyons,cwong,dbarber,dmuse,dnicol,edougher,egallant,ekubosia,evizcain,feeddrop,gtulonen,halokush,hbraverm,jbartus,jbrown,jhobbs,jking,jlederma,jpecora,jthayer,kbalbedi,kbeam,kginn,mbuonfig,mcrawfor,mlarsen,mlong,mwalsh,osedano,proche,prondeau,pweinber,rhorriga,rkersey,rskutins,sasaro,sbrodeur,sculver,smoriart,support,swestenh,tbaltimo,torgelfi,usmall,vvalenti Has anyone encountered a similar problem with nss_ldap or pam_ldap?

CentOS-5 - Suffering from LDAP experimentation
by James B. Byrne 27 Sep '07

27 Sep '07

I was playing aeound with the GUI authentication configuration and was called away from my desk after I had configured the LDAP DC entries but before I had tried to start the ldap server or do much of anything else. When I returned the terminal session was screen-saver locked and entering my user password did not make it respond. I kept getting a time-out error. Rebooting took forever and was delayed for long periods at two points that I do not recall as being problems before; Loading IPtablesv6? and Starting system message bus. More importantly the user GUI takes forever to start. I am seeing these entries in the /var/log/merssages filr (vis ssh login through another system.): Sep 27 15:37:13 inet02 perl: nss_ldap: failed to bind to LDAP server ldap://127.0.0.1: Can't contact LDAP server Sep 27 15:37:13 inet02 perl: nss_ldap: reconnecting to LDAP server (sleeping 8 seconds)... Sep 27 15:37:21 inet02 perl: nss_ldap: failed to bind to LDAP server ldap://127.0.0.1: Can't contact LDAP server ... Sep 27 15:43:26 inet02 gdm[3483]: nss_ldap: failed to bind to LDAP server ldap://127.0.0.1: Can't contact LDAP server Sep 27 15:43:26 inet02 gdm[3483]: nss_ldap: could not search LDAP server - Server is unavailable So, how do I undo whateever it is I borked when I experimented with LDAP? This is a rtestbox aso a re-install is not out of the question. I am digest subscriber so if you could copy me directly on any reply to the list I would be very appreciative.

Waking up X
by semi linux 27 Sep '07

27 Sep '07

I just finished installing CentOS 5 (again)... and I'm having trouble with my X config (I _think_). If I 'startx' then switch to a console (using CTRL+ALT+F*) and then back to X (CTRL+ALT+F7), 1/2 the time it comes back, the other half I get a black screen and I can never recover the session. X is still running (CTRL+ALT+Backspace kills it) but there seems to be some type of power saving or screensaver that kicks in and won't let the session restore... Any hints on where to look? The X logs don't _seem_ to show anything... - G.
