Re: [xcat-user] update xCAT genesis kernel

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

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

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. V. > On 28 Nov

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

That is correct, diskless and statelite both support local disk for different purposes now.   Best Regards--Yuan Bai (白媛)CSTL HPC System Management DevelopmentTel:86-10-82451401E-mail: by...@cn.ibm.comAddress: IBM ZGC Campus. Ring Building

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

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. Regards, Christian Caruthers Lenovo Professional Services Mobile: 757-289-9872

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

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?

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

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. [http://lenovocentral.lenovo.com/marketing/branding/email_signature/images/gradient.gif] Gilad Berman HPC

[xcat-user] Managing user's SSH configuration with xCAT

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! --

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

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

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

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.

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

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: All,   I would like to join this question – Does even localdisk works with stateless? From the docs it seems that

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

All, I would like to join this question – Does even localdisk works with stateless? From the docs it seems that should be supported (because it is under stateless), however – - the instructions are taken from statelite and refer to statelite code (litefile) - The rc.localdisk
