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.
