[xcat-user] Bootparams table is empty

[Russ Auld]

I'm setting up a new xCAT master on a RHEL7 system.  I'm using v2.13.8.I ran copycds on the rhel7 iOS.When I run nodeset the bootparams table remains empty and there is no initrd  or kcmdline  set for the node. Dracut  then fails when the node boots. It's  set for pxe  boot and it does do that. What updates the bootparams table? --

This is a "known defect" with the CentOS templates, please see
https://github.com/xcat2/xcat-core/issues/3103 for a fix.

[xcat-user] xCAT 2.3.18: copycds does not create centos7-x86_64-install-service osimage

[Keith Ball]

Hi All,

I have installed xCAT 2.3.18 on a Centos 7.3 management node, and am using
Postgresql as the database. I am planning to provision a service node.

When I run "copycds CentOS-7-x86_64-Everything-1611.iso", only the
following stock osimages are created:
  centos7.3-x86_64-install-compute
  centos7.3-x86_64-netboot-compute
  centos7.3-x86_64-statelite-compute

**However**, there is no "centos7.3-x86_64-install-service" image created!

I have looked at /opt/xcat/lib/perl/xCAT/SvrUtils.pm (seems to be doing the
"heavy lifting" behind the scenes for copycds), but cannot figure out
what's keeping the "install-service" from being created. Was it removed
from xCAT for centos7 versions? (I have another xCAT cluster on centos7.3
at xCAT 2.13.7 that also did not build a service node osimage).

That being said:

1.) Any idea how I can get "copycds" (or other xcat action) to actually
build a service node osimage?

2.) If xCAT won't create the image, is there a way that I can reliable
hand-create the osimage for a service node e.g. by copying the
install-compute image and adding specific packages? (my concern here is
that xCAT and Postgresql, etc. items be propagated to the service node as
needed).

Many Thanks,
  Keith

Re: [xcat-user] Local scratch for stateless compute nodes

[Vinícius Ferrão]

Wow… thank you so much Bin.

“nodeset" done the trick too. It worked on CentOS 7.4.

Just an additional note, when creating definitions with chtab the trailling 
slash on directories must be written or else a file will be created instead of 
a directory:

Mount /dev/sda2 to /.sllocal/localmnt with xfs
mount -t xfs /dev/sda2 /sysroot/.sllocal/localmnt
DEBUG: SYNCTOLOCAL=1
mkdir -p /sysroot/tmp/
mkdir -p /sysroot/.sllocal/localmnt/tmp/
mount --bind /sysroot/.sllocal/localmnt/tmp/ /sysroot/tmp/
touch /sysroot/work
touch /sysroot/.sllocal/localmnt/work
mount --bind /sysroot/.sllocal/localmnt/work /sysroot/work

After editing the lines with tabedit litefile it worked as expected.

Thanks,
V.

[xcat-user] Network Log servers and NTP servers.

[Hakan Bayındır]

Hello,

I'm slowly configuring my xCAT installation further, and want to define
log servers and NTP servers to my CNs during installation.

As far as I understood, if undefined, xCAT MN is used as NTP and log
server if none defined, however our cluster have a central log and NTP
server.

How can I add these servers in addition to the list so, the CNs have two
NTP server addresses and two log server targets?

Thanks in advance,

Hakan

Re: [xcat-user] update xCAT genesis kernel

[Imam Toufique]

Hi Zhao,

thanks for the quick reply!  So, here is another question, which I am not
sure about.  My xCAT MN is in on centOS7.4 and in my cluster, all nodes are
on centOS 6.9 .  If I build the Intel X722 10G NIC driver in centOS7 for
Genesis (in MN), would that work in centOS6.9?  I guess I will be building
the driver for centOS7, genesis kernel might be able to image the node, but
I am not sure if that node will actually work after the build is complete?
i guess the difference here is that the MN is on centos7 and my machines
are running centos 6.9.

thanks.

[xcat-user] software RAID SETUP -- best practices?

[Imam Toufique]

Hi,

I need to start understanding how software  RAID setup works with xcat (in
centOS 6) , although it is not my favorite topic. :) . I have 2 disks that
I would like to setup RAID1 with.

I see there is a script that can help set up to do RAID1, it is here:

wget 
https://raw.githubusercontent.com/xcat2/xcat-extensions/master/partition/raid1_rh.sh
\
 -O /install/custom/partition/raid1_rh.sh

Is the above script good enough to setup RAID1 or should I look at the
template file?
the template file has something like this:

#Full RAID 1 Sample
#part raid.01 --size 50 --ondisk sda
#part raid.02 --size 50 --ondisk sdb
#raid /boot --level 1 --device md0 raid.01 raid.02
#

What is the best way to do this?  Can you share some thoughts or your
best practices?

thanks.
