[CentOS] 4kB sector size HDDs
Hello again. Do any of you have one of the 'new' HDDs with 4kB Sectors currently in use? I would upgrade to the 4kB disks but I don't know if this might be problematic as I intend to use ZFS w/ RAIDz or at least a classic RAID6.

It sounds to me like your big beef is that you can't run the CentOS distribution the way *you* want it run. Whether you agree or not, doesn't change the fact that CentOS *is* enterprise ready.-- and many enterprises use it. The only time there are significant delays in No, I would just like the name and website to match the facts. I would suggest that anybody that calls centOS enterprise-ready might have a different concept to what an enterprise is to me. Enterprise to me is at least a 1000 users and dozens of live servers. If CentOS is only suitable for test environment then I don't really class that as enterprise-ready, either. As for rebuilding, why would you want to rebuild CentOS? Why not do what CentOS does and get the sources directly from Red Hat and rebuild that? Obviously you must think there is still some value in the CentOS name.

Re: [CentOS] 4kB sector size HDDs
how do I go about setting up the alignment of the partitions I use? If you use one large partition it's easy: you just create the partition leaving 1 meg of free space before the partition. This causes the partition to start at sector 2048, which is a number that 4096 is divisible by. Newer versions of disk utilities like gparted suggest this for you by placing a 1 in the 'Free Space Preceding' box when you go to create a new partition. If you create multiple partitions, it's a little harder since you have make sure that subsequent partitions start on sectors that can be divided evenly into 4096. I've never done this as I always set up one large partition on my storage arrays, and I use a separate drive for the OS to boot from and another separate drive for my VMs. I do this for performance reasons.

Do any of you have one of the 'new' HDDs with 4kB Sectors currently in

I have them in use, and set up the partitions manually before installing
the OS. This is the relevent entry from my server changelog, prior to
installing CentOS 5.5:
+ since this machine is using new drives with 4k blocks,
used fdisk to ensure that sector alignment will be sane:
fdisk -H 224 -S 56 /dev/sd{a,b}
In doing so, I created a 200MB RAID1 partition (type 0xfd)
and another RAID1 partition with the remaining disk for use
by LVM.
I found it necessary to use fdisk manually on both disks,
because the following command choked (probably due to
the geometry thing):
sfdisk -d /dev/sda | sfdisk /dev/sdb
(DOESN'T WORK)
I case it's not obvious, the partitions on sda and sdb are then
mirrored, the small one for /boot, the large one for the remaining
filesystems under LVM.
If you're using the Caviar green drives, beware of excessive head
park and quickly increasing load cycle counts. I fixed that with
using an idle timeout of 300 seconds (vice 8 seconds) per:

If CentOS is only suitable for test environment then I don't really class that as enterprise-ready, either. Dozens ? What a small environment. My concept of enterprise is thousands of servers. CentOS, as an Operating System, is most definitely enterprise ready. It can scale to 1000s of servers quite easily. Tools are available to let you build and deploy on an automated basis. You could deploy CentOS to a thousand servers with ease; you could deploy a blade farm with dynamic provisioning very quickly and easily. What the CentOS project is _not_ is an enterprise level _support_ service. It doesn't pretend to be. That's where the community aspect comes in. If you want enteprise level support then you probably need to pay for it. (which is why my employer uses RedHat and not CentOS; we want to be able to phone someone and bitch at them until they fix stuff) If you consider enterprise ready to be a combination of enterprise scalable and enterprise level support then, sure, you'll not find CentOS meeting your needs. But if you want an enterprise quality OS then CentOS fills that gap nicely. -- rgds Stephen ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] CentOS 5.6 and KVM failure
2011/4/21 Ian Forde ianfo...@gmail.com: Turns out that wasn't the only problem I faced in my migration. With 2 KVM servers, both sharing a volume mounted via NFS for VMs, I migrated all VMs to the second node, upgraded the first, them moved them all back to KVM1. Instant disk corruption on all VMs. Boom. Are you sure it was the migration and not the raw/qcow2 error which caused the disk corruption? I just had two Windows Servers with image corruption after upgrading from 5.5 to 5.6 and booting the first time with the raw setting, before changing it to qcow2 :-/ These two images were both on the same host, which is plain CentOS 5 *BUT* with a 2.6.37 kernel (and therefore 2.6.37 KVM module) from elrepo... It could be my special case of running with a vanilla KVM-module + CentOS KVM userspace which allows the corruption to happen, but if other people are seeing disk corruption with the regular kernel/kmod-kvm, then this known issue should probably have a big fat red warning in the release notes..

[CentOS] User accounts management for small office
Greetings - This may be a little off-topic here so if someone wants to point me to a more appropriate mailing list I would appreciate it. I administer the network for my small company and am preparing to install a new server in the next month or so. It will be running CentOS 6 and function primarily as a Samba file server to 10 Windows workstations (XP, Vista, 7). It will also host our OpenVPN server and possibly our FTP server; however I am hoping to move our FTP server to a gateway box when the new server is installed. The issue that I would like to be able to resolve when the new server is installed, is that currently if a user wants to change the password on their Windows workstation, I have to manually update that new password on the Linux user account, and also manually change the Samba user account. Manually updating the password in three different locations is a minor headache that I would like to correct. I have been researching and reading lots of information about account management to try and understand what is available, and what would be the best fit for my network size. Much of what I have read is related to larger networks or larger user bases, which seem to have a lot of extraneous stuff that would be unnecessary in my small user environment. I looked into OpenLDAP, and have recently been reading about Samba/Winbind. But after encountering the following statement in the Samba documentation, I am still lost about what I could, or should, be using. A standalone Samba server is an implementation that is not a member of a Windows NT4 domain, a Windows 200X Active Directory domain, or a Samba domain. By definition, this means that users and groups will be created and controlled locally, and the identity of a network user must match a local UNIX/Linux user login. The IDMAP facility is therefore of little to no interest, winbind will not be necessary, and the IDMAP facility will not be relevant or of interest. My only goal is to be able to allow my users to change their Windows password at their workstation and have it perpetuate through the system so that it also changes their Linux User and Samba User account passwords. I don't expect to ever have more than a dozen users, so I want something that fits our size network and is simple to administer. I am not looking for a how-to to set something up, but some opinions about what I should consider using, and why it would be a good fit to achieve my goal. I can do the additional research to understand configuration once I know what I should be researching. Thanks. Please cc me directly, as I only get the list in daily digest mode.

That's exactly what you've seen amongst some spacewalk users. FWIW, there are some out there who don't even think unsigned packages are a problem. As an extreme example of this, recently I saw on LinuxToday where there was a thread in an archlinux list about signed packages; most of the devs didn't consider them a priority. At all. One reason arch won't be in production here any time soon.

Yes, agreed OpenLDAP is my suggestion as well. As for Windows clients, you can either do; Samba/LDAP tie in so that your LDAP domain also function as a PDC. Or you can use pGina which is a Windows LDAP plugin that allows your Windows clients to auth direct to LDAP w/o the need to join a PDC first. I prefer pGina but its not for every one. - aurf ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

If what I have seen/read is correct, 'virsh edit' has an additional feature. It will check for errors upon exit. So, it's much like visudo (versus vi). When you move kvm guests across different platforms (for example Fedora to CentOS), editing config files using 'virsh edit' will help. In this case, you will be running 'virsh define' which may also have a checking mechanism (not quite sure about this though).

I administer the network for my small company and am preparing to install a new server in the next month or so. It will be running CentOS 6 and function primarily as a Samba file server to 10 Windows workstations (XP, Vista, 7). It will also host our OpenVPN server and possibly our FTP server; however I am hoping to move our FTP server to a gateway box when the new server is installed. Have you looked at the ClearOS distribution? It comes up with a simple web interface to manage all of this with authentication done with a pre-configured LDAP setup. I think LDAP replication is slated for the next version - which is waiting for CentOS 6 for it's components but you'd only need that if you have several different servers and want changes to propagate across them. Actually, I found webmin helpful in setting up and testing openldap. Webmin is a very different concept. It is a mostly a web-form editor for the underlying program's config file that may know enough to keep you from making/saving the kinds of syntax errors that you can make with a normal text editor, but you still have to know what program to start for each service, know the relationships between programs, and make separate changes to each program, knowing what all of the options do. ClearOS and the similar/earlier SME server are much more task/service oriented with preconfigured settings to make the common services you want come up and forms that relate to what you want to do rather than having to deal with options in several different different underlying programs. So even though it is running the same samba and openldap as a Centos install, you don't need to change anything to make them work together. And some things that are conceptually even harder, like optionally enabling openvpn per user and generating client certificates are checkbox/push button items. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Re: [CentOS] User accounts management for small office
I'd say base it on OpenLDAP. As far as the password change option, one simple but effective system is the passwd.cgi script from cgipaf: http://freshmeat.net/projects/cgipaf/ Although you already have to provide your old password to do an update, putting it behind http-basic authentication will allow you to use things like fail2ban to protect against brute forcing.

Yes, cgipaf will allow you to change samba passwords at the same time, but it's been a few years since I needed to support samba and so I don't have a *current* assessment of it.

[CentOS] iscsi multipath fails
Hi all, I have a Dell server running cent 5.6, new install, connecting to an IBM DS3500. I have configured iscsi connections using iscsid and can log into the targets on the IBM. I can also mount the LUNs when accessing them from their active controller path. When I throw multipath into the mix, it fails completely. Multipath is working, when I run multipath -ll it shows me the correct active path and it is mapped to a device under /dev/mapper. However, if I try to access the device from that path, no luck. A mount request just hangs and eventually there's a kernel error message. I'm using the native rdac drivers that came with the OS. Anyone using something similar? My guess is that it's either bad drivers, or a bad multipath config. I started with the default, but after tweaking different parameters, it's still not working. Any advice is greatly appreciated. thanks, Adam Wead ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You should not need to do anything in virsh to dump a file ... there

The XML-files in /etc/libvirt/qemu represent libvirt defined VMs, you

Problem may be an SELinux problem. Here is the alert. Notice the
reference to '/dev/hda' (which is the virtual machine boot disk), and
the SELinux context 'virt_content_t'
I'm going to create /.autorelable and reboot to ensure the upgrade
properly relabled the filesystems.
Summary:
SELinux is preventing pam_console_app (pam_console_t) getattr
to /dev/hda
(virt_content_t).
Detailed Description:
SELinux denied access requested by pam_console_app. It is not expected
that this
access is required by pam_console_app and this access may signal an
intrusion
attempt. It is also possible that the specific version or configuration
of the
application is causing it to require additional access.
Allowing Access:
Sometimes labeling problems can cause SELinux denials. You could try to
restore
the default system file context for /dev/hda,
restorecon -v '/dev/hda'
If this does not work, there is currently no automatic way to allow this
access.
Instead, you can generate a local policy module to allow this access -
see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can
disable
SELinux protection altogether. Disabling SELinux protection is not
recommended.
