Hi Zhao,
thanks for doing this! I do have a few questions since I am not an expert
in working with genesis. ;-)
the procedure of installation as you mentioned, will it work with
xcat version 2.13.7 ? I have xcat 2.13.7 installed now in my LAB setup, I
am planning to upgrade very soon to versio
Please take a look of the 'xdsh -K -l [user]'.

Hello,
Please refer to "Enabling the localdisk Option" section under "diskless installation" section : http://xcat-docs.readthedocs.io/en/latest/guides/admin-guides/manage_clusters/ppc64le/diskless/customize_image/localdisk.html
The main diskless installation doc link is here:

Hello,
The major problem is the missing documentation on how to use the local disks on
a stateless (diskless) installation. Tricks are being deployed instead.
Trying to mimic the steps of a statelite installation is not sufficient to make
it work on stateless deployments.

That is correct, diskless and statelite both support local disk for different purposes now.

Hi Kevin,
Please refer to http://xcat-docs.readthedocs.io/en/latest/advanced/security/security.html#commands-access-control
Here is "Granting Users xCAT Privileges" topics.

We’ve used similar scripts in the past without any checks to prevent unintended
disasters. It would be pretty easy to use an if or case statement to ensure
anything destructive only happens on the right systems.

Very good info indeed. I will be looking on the script, Kevin.
It would be sufficient for a while, but about the feature, it would be nice to
be fixed/documented/explained how to use it, because it’s a pretty common use
case of stateless nodes.
Perhaps someone on the dev team can look at this?
THX Kevin for the tip!!
We actually used similar method, but the first post on the thread reminded me
of the localdisk feature and I thought it can be very nice to use it, if
working.

xCAT seems to be very good at managing root's known_hosts file, and
distributing root's SSH key to the nodes for passwordless logon. I believe
this is done by updatenodes.
Can xCAT do the same for ordinary users as well? I have not found a way to
do it yet.
Thanks!

To address this, we are using the syncfiles mechanism to copy an rc.local
file into the compute node (we could probably also put it directly into the
image)
This rc.local contains statements to mount the /tmp volume. We originally
also used it to partition and format the physical hard disk, but th
Hello,
Accordingly to the documentation they are different on a specific way:
. Stateless: nodes boot from a RAMdisk OS image downloaded from the xCAT mgmt
node or service node at boot time.
. Statelite: nodes boot from an NFS-root diskless OS image.
And both support local disk for different p
1. I use local disk for scratch and swap. Somethings logs as well (in this
case you can think of it as sort of statelite, but from xCAT perspective, it is
still stateless).
2. I took only the part that not relate to statelite from the instructions
– not working.

If you're using netboot and local disk, then isn't that "statelite"?Do the satellite instructions not work? On Nov 27, 2017 9:26 AM, Gilad Berman wrote:
