Re: [CentOS] Easy way to strip down CentOS?
The best way to do this is a new minimal install either in the GUI installer or with kickstart. And build up from there. If you do an install to e.g. CentOS-base.qcow2, that image already has machine-id and hostname set. While not running a VM, use guestfish to mount the qcow2, and make /etc/machine-id empty. Now, only use this base.qcow2 as a backing image. That is, never use it directly in a VM. Use qemu-img create -b base.qcow2 -f qcow2 guest1.qcow2 qemu-img create -b base.qcow2 -f qcow2 guest2.qcow2 qemu-img create -b base.qcow2 -f qcow2 guest3.qcow2 Now use the guestn.qcow2 in the VM. And at first boot, the machine-id will be populated. I'm not sure of any negative consequences of not doing this, but if you want to use remote journalling it's necessary so that the single journal can keep machines uniquely identified (even when changing the hostname). http://fedoraproject.org/wiki/Changes/Remote_Journal_Logging https://kashyapc.fedorapeople.org/virt/lc-2012/snapshots-handout.html Extra info: Anaconda uses this on lives to do installations (quite a few of these options are consolidated with -a): rsync -pogAXtlHrDx -- Chris Murphy ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] C7, igb and DCB support for pause frame ?
Hi there, I’m working on deploying our new cluster. Masters have 5×1gbps (i210 and i350, thus using igb.ko), configured with mtu 9000, 802.3ad. Works fine *but* I can’t get DCB working (pause frame, aka flow control, which is supported by and enabled on our switches). [root@master2 ~]# dcbtool gc eno1 dcb Command:Get Config Feature:DCB State Port: eno1 Status: Device not capable (I get the same with ELRepo 5.2.15 kmod).

Re: [CentOS] Easy way to strip down CentOS?
Ok, I understand, now. I just leave multiple desktops in place and switch between them as I want. But perhaps you have reasons to do it as you do. That is one thing I really appreciate about Linux, the fact that there are many, many ways to accomplish almost everything and that what is right and works for me may not be what works best for you. Your scripting style is irrelevant so long as it gets the job done for you. And one tenet the Unix/Linux Philosophy is, "automate everything," which is what you have done.

[CentOS] move a disk to another machine

Check the installed kernel append line to make sure the rdblacklist option
is not being pulled from the kickstart boot line. If it is you can add
this to the kickstart post install section:
/usr/bin/perl -p -i -e 's/rdblacklist=MODULENAME//' /boot/grub/grub.conf
So for port 2 (eth1), the kickstart file has it configured as a dhcp
interface, so why when the system reboots it comes up with
bootproto=none?
As I pointed out the script I sent changes all interfaces to DHCP=none.
If you are using it and you don't want it to do that then remove this line:
/usr/bin/perl -p -i -e 's/dhcp/none/'
/etc/sysconfig/network-scripts/ifcfg-${NETDEV}-tmp
On the other hand, port 1 (eth0) does come up with the static information

That's what I figured, so I can remove it from the kickstart file, no
problem. The question then becomes, if kickstart doesn't configure it,
what
happens when the system reboots after install? It won't know what to do
with that interface, correct?
Is this a case where I will need to put an ifcfg-eth2 file in place
during post-install?
Upon reboot the system *should* generate a base one for you as it will
see it as a new interface. Not a big deal if it does not though, just
create one yourself. You will want to add it to the udev rules file
though. You can re-run the script I sent to do that if you want. At
that
point it should be eth2. Or you can edit the existing one by copying a
line and changing the MAC and eth* to whatever you need.

[CentOS] How to search the mail archive
Hey All, I've seen references to searching the mail archive. How exactly does one perform such a search? Let's say I want to search the mail archive for references to the scp command.

Re: [CentOS] Kickstart with multiple eth devices
Nope, it doesn't add it to the kernel boot parameters. That was the first
thing I checked.
As for the bootproto ... DUH. I didn't check that. :) That being solved,
yeah it's not bringing up the add-in card now when it boots up.

That's what I figured, so I can remove it from the kickstart file, no
problem. The question then becomes, if kickstart doesn't configure it,
what
happens when the system reboots after install? It won't know what to do
with that interface, correct?
Is this a case where I will need to put an ifcfg-eth2 file in place
during post-install?
Upon reboot the system *should* generate a base one for you as it will
see it as a new interface. Not a big deal if it does not though, just
create one yourself. You will want to add it to the udev rules file
though. You can re-run the script I sent to do that if you want. At
that
point it should be eth2. Or you can edit the existing one by copying a
line and changing the MAC and eth* to whatever you need.

Re: [CentOS] Kickstart with multiple eth devices
What about a blacklist line somewhere in /etc/modprobe.d ?
I have never noticed anaconda adding one there but it is worth checking.
Also, when you check dmesg, are you looking for the expected module name
or eth2?

As I pointed out the script I sent changes all interfaces to DHCP=none.
If you are using it and you don't want it to do that then remove this
line:
/usr/bin/perl -p -i -e 's/dhcp/none/'

On the other hand, port 1 (eth0) does come up with the static

Re: [CentOS] Kickstart with multiple eth devices
I have a Dell server that has two built-in ethernet devices. When I kickstart the machine, they are correctly identified as eth0 and eth1 (correctly meaning they correspond to the physical device ports 1 and 2). I need a third one and want that to come up as eth2. After adding the hardware, kickstart now fails because for some reason it goes through a rename process where it makes the newly added card eth1 (or eth0, I forgot). Is there a way to stop this rename process so kickstart correctly uses the physical hardware the way they are, meaning physical port 1 = eth0, port 2 = eth1, and the additional ethernet card then becomes eth2? Should I be using the device's MAC address when I set the 'network' option in the kickstart file? So instead of 'network --device=eth0' I make it 'network -device=aa;bb:cc:dd:eee:ff' ? ksdevice=aa;bb:cc:dd:ee:ff in your above example will ensure the device with that mac is the kickstart device. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] scp -rp behavior
Hey all, I'm trying to copy configuration files from my old CentOS 6.6 32 bit machine to my new CentOS 6.6 64 bit machine. On my 32 bit machine: [mlapier@mushroom ~]$ ifconfig eth0 Link encap:Ethernet HWaddr 00:19:DB:E5:4E:9F inet addr:192.168.15.105 When I issue this command on my new 64 bit machine, 192.168.15.101: scp -pr mlapier@192.168.15.105: /home/mlapier/.thunderbird /home/mlapier/.thunderbird It copies all directories and files in 192.168.15.105: /home/mlapier/ to 192.168.15.101: /home/mlapier. I don't want all that, I just want the .thunderbird folder and all it's contents. The user and group account numbers match on the two machines for this user so that's not the issue. When I RTFM this is what I thought it said to do.

Also, if you want to specify destination directory (say with different name) you will need to end directory with forward slash both on local and remote, like: scp -pr mlapier@192.168.15.105:"/home/mlapier/.thunderbird/" \ /home/mlapier/.thunderbird/ (this should be one line which didn't fit for me in one line hence backslash...)

The two are often confused and not compatible. http://www.intel.com/content/www/us/en/ethernet-controllers/ethernet-controller-i350-datasheet.html Mentions "flow control" several times, but never PFC/priority-flow-control/802.1Qbb. PFC capable switches purposefully disable 802.3x flow control. Also PFC has to negotiate between two devices/switches matching QoS/CoS/no-drop policies.

Typically FCoE/iSCSI is set to "no-drop" and Ethernet traffic is paused/dropped in favor of storage traffic. If there is only one type/class/CoS of traffic PFC won't gain much over regular flow control/802.3x.

I just tested and confirmed it. Some other notes: with the "mlapier@192.168.15.105" you'll, by default, be "in" the home directory of mlapier on the remote machine. So you don't need the "...:/home/mlapier/" pathing. Also, if you are in your (mlapier) home directory on the new machine when you are doing this you again won't need the pathing. So, I think you should be able to do just: scp -pr mlapier@192.168.15.105:.thunderbird . or at most: scp -pr mlapier@192.168.15.105:.thunderbird /home/mlapier/. If, per chance, you wanted to change the directory name on the transfer you'd need to specify it, rather than just the ".", otherwise the "." will simply put directory on the target machine with the same name as the original. - Richard ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
