Chipset support for 6750 Intel CPUs
by Drew Weaver 08 Dec '07

08 Dec '07

Howdy, We've noticed that the new chipsets required for the **50 series of intel processors is not supported in CentOS 5. We've tried the DG31 board which (realtek nic unsupported) DG33 no support for disk controller or NICs. We also tried the dx38bt and there was no support. Fedora 8 apparently works great with all of the boards we tried. My question is, will there these boards not be supported via the installer until CentOS 6? I realize that the driver support comes from upstream, but it would be cool if they made a easy way to use a newer/updated kernel in the installer. Thanks, -Drew

yum upgrade fails on pm-utils dependancy

I just tried to perform a yum upgrade on my CentOS 5 machine and it failed on a pm-utils >= 0.99.3-6 is needed by package hal error. I rsync my repos every night.

LDAP and Automount
by Camron W. Fox 08 Dec '07

08 Dec '07

Alle, I'm following the instructions in section 19.3.3.2 of the docs @ http://www.centos.org/docs/5/html/5.1/Deployment_Guide/s2-nfs-config-autofs…, but I cannot add the following entry in LDAP: dn: automountMapName=auto.home,dc=subaru,dc=nao,dc=ac,dc=jp objectClass: top objectClass: automountMap automountMapName: auto.home After looking at the schemas in /etc/openldap/schema, I find that "automountMapName" does not exist: [root@loa schema]# find . -exec grep auto {} \; -ls attributetype ( 1.3.6.1.1.1.1.25 NAME 'automountInformation' DESC 'Information used by the autofs automounter' objectclass ( 1.3.6.1.1.1.1.13 NAME 'automount' SUP top STRUCTURAL DESC 'An entry in an automounter map' MUST ( cn $ automountInformation ) objectclass ( 1.3.6.1.4.1.2312.4.2.2 NAME 'automountMap' SUP top STRUCTURAL DESC 'An group of related automount objects' 4425955 4 -rw-r--r-- 1 root root 748 Nov 10 04:30 ./redhat/autofs.schema [root@loa schema]# The docs say RFC2307bis is the most recently established schema, but as far as I can tell, it has expired. I've found several references on line about nisMapName vs automountMapName, but I'd like to stay with what's documented. Am I missing something? We're trying to setup a server to use for both Linux and SPARC client authentication. Best Regards, Camron -- Camron W. Fox Hilo Office High Performance Computing Group Fujitsu America, INC.

I have some suspect drives that had errors report but format fine at the controller level. I would like to see how many bad blocks the format encountered and remapped. If there are a large number of these then I do not want to use the drives in any critical applications. If the number is small then I will assume that the drive is basically fine to use and that the errors were localized. Since I posted my original inquiry I have discovered that some of the drive manufacturers have T&D utilities that might allow me to get at this information. The main problem here is that they tend to be Windows based which means that I will need to setup a Windows system just to test the drives. I would rather test them in the systems that the will be running in (one is CentOS 4.5 and one is RHEL3). Seagate does have an older utility that supposedly will run at the Linux CLI (their terminology) which I will be trying out.

mounting nfs as httpd_sys_content_t under selinux
by Johnny Tan 07 Dec '07

07 Dec '07

I have a NFS mount that I want apache to be able to serve files from. According to this doc: http://www.centos.org/docs/5/html/5.1/Deployment_Guide/rhlcommon-section-00… I should be able to mount it with a context that will allow apache to access it. But when I try the command they suggest: [root@vm-37:~] mount -t nfs -o \ context=system_u:object_r:httpd_sys_content_t \ 192.168.1.100:/data/test /mnt/test It mounts, but when I do: [root@vm-37:~]# ls -lZ /mnt drwxr-xr-x 65534 65534 system_u:object_r:nfs_t test It doesn't show the correct context. (I don't know if it matters that I don't have a user with UID 65534, only the remote NFS server has that.) And sure enough, apache still can't serve from it. I see this in /var/log/messages: Dec 7 17:30:14 vm-37 kernel: audit(1197066614.787:240): avc: denied { search } for pid=18066 comm="httpd" name= "" dev=0:14 ino=4301717509 scontext=root:system_r:httpd_t:s0 tcontext=system_u:object_r:nfs_t:s0 tclass=dir Dec 7 17:30:14 vm-37 kernel: audit(1197066614.787:241): avc: denied { getattr } for pid=18066 comm="httpd" name ="" dev=0:14 ino=4301717509 scontext=root:system_r:httpd_t:s0 tcontext=system_u:object_r:nfs_t:s0 tclass=dir When I "setenforce 0", it works. But I want SELinux. Granted, I could do: allow httpd_t nfs_t:dir { search getattr }; Well, actually, I haven't tried it but I'm guessing that that will work. The problem is that I have other nfs directories that I don't want httpd to access, even accidentally if we ever point httpd at those directories. So... any ideas on the nfs mount with the context option? I'm running CentOS-5.1 with latest updates of everything. johnn

CentOS 5.1 on intel DQ35JO , Q35 chipsed based board
by David Hláčik 07 Dec '07

07 Dec '07

Hi, i was trying to install CentOS 5.1 on new machine based on Intel Q35 desktop board, witch 2 SATA disks (configured as RAID 1) , 8GB RAM and Intel Core2 QUADCORE. The first problem was with install - it hangs before installer startup at ACPI messages. So i installed it with ACPI=off switch. The first problem is : Dec 7 09:54:01 vmhost1 kernel: BIOS bug, no explicit IRQ entries, using default mptable. (tell your hw vendor) Dec 7 09:54:01 vmhost1 kernel: Processors: 1 Which kernel should i use? I have default installed kernel. The second problem is with LVM (probably raid on board - in bios i switched in sata mode to raid, and created in raid utility RAID1 volume from those 2 disks: /dev/sdb1 [ 101.94 MB] Found duplicate PV hpGVb3U5Q0lxFe1LN6eJpSCJSWs0xfpu: using /dev/sdb2 not /dev/sda2 /dev/sdb2 [ 297.99 GB] LVM physical volume [root@vmhost1 archive]# What does it means and how can i fix this? Thanks a lot David Hlacik

RAID-1 strategy for a CentOS/Xen server?
by Bob Tomkins 07 Dec '07

07 Dec '07

Hi, I'm planning to migrate my current server configuration: AMD Athlon/X2 FreeBSD 62-Release 2 x 250GB HW RAID1 (all partitions RAIDed, incl. swap) to a Xen/CentOS config: AMD Athlon/X2 Dom0 CentOS 51 Xen 31 Dom1/1 FreeBSD 7 Dom1/2 CentOS 51 ... To "best preserve" RAID1 mirroring protections of OS, Data, etc *AND* optimize performance, how should I setup RAID for the "new" configurations? Should DOM0 be RAIDed? Each DOM1, as well? Should I continue to use HW RAID or switch to SW? A mix? I understand I can do any/all ... choosing the "right" option is the goal, here. Advice is appreciated. Regards, Bob Tompkins

Minimal install for CentOS 5?
by Aaron Seelye 07 Dec '07

07 Dec '07

Hello, I'm new to the linux world (long time FreeBSD user), and I'm wondering if there's an easy way to install CentOS 5 without the GUI and unnecessary services? I see there's a server cd for CentOS 4, but I didnt see anything like that for CentOS 5. Am I looking in the wrong places, or is it just necessary to manually select the minimal set of packages? Thanks, Aaron Seelye
