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?

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 code is under statelite
- In the linuximage man – “Partitionfile - Only available for diskful
osimages and statelite osimages(localdisk enabled)“
A very quick trial on my statless nodes results in nothing ☺, it seems there is
simply no reference to localdisk with stateless.
So, can someone please help clarify it?
** as always, there is a chance I missed something very basic and it should be
working ☺
THX in advance!

Subject: [xcat-user] Local scratch for stateless compute nodes
Hello,
I would like to enable swap and local /tmp on my stateless nodes, but after
following the documentation on the following link nothing appears to work:
http://xcat-docs.readthedocs.io/en/stable/advanced/hierarchy/provision/diskless_sn.html
I’m aware that the documentation is for service nodes and not for compute
nodes, but I was thinking the procedure would be similar.
At this point I’m with this settings on osimage:
[root@headnode xcat]# lsdef -t osimage centos7.4-x86_64-netboot-compute
exlist=/opt/xcat/share/xcat/netboot/centos/compute.centos7.exlist
imagetype=linux
osarch=x86_64
osdistroname=centos7.4-x86_64
osname=Linux
osvers=centos7.4
otherpkgdir=/install/post/otherpkgs/centos7.4/x86_64
****
partitionfile=/install/custom/netboot/centos7.4-x86_64-netboot-compute/partitionfile
permission=755
pkgdir=/install/centos7.4/x86_64
pkglist=/opt/xcat/share/xcat/netboot/centos/compute.centos7.pkglist
postinstall=/opt/xcat/share/xcat/netboot/centos/compute.centos7.postinstall
profile=compute
provmethod=netboot
rootimgdir=/install/netboot/centos7.4/x86_64/compute
synclists=/install/custom/netboot/compute.synclist
And the content of the partition file is the following:
cat /install/custom/netboot/centos7.4-x86_64-netboot-compute/partitionfile
enable=yes
enablepart=yes
[disk]
dev=/dev/sda
clear=yes
parts=10,90
[swapspace]
dev=/dev/sda1
[localspace]
dev=/dev/sda2
fstype=xfs
Finally the following commands were executed:
chtab priority=7.1 policy.commands=getpartition policy.rule=allow
chtab litefile.image=centos7.4-x86_64-netboot-compute litefile.file=/var/log/
litefile.options=localdisk
chtab litefile.image=centos7.4-x86_64-netboot-compute litefile.file=/tmp/
litefile.options=localdisk
After a new genimage/packimage the local scratch does not appears to be made
nor working.
Someone knows what to do next?
Thanks,
V.
