Hi , ALL
I think the key is how to pack the diskless image
xCAT have the packimage to generate the diskless image ,and you diskless image
is use the tar command ,which may not fit the need
[root@mgt ~]# packimage -h
Usage:
packimage [-m| --method=cpio|tar] [-c| --compress=gzip|pigz|xz] <imagename>
packimage [-h| --help]
packimage [-v| --version]
[root@mgt ~]#
[root@mgt ~]# history | grep packimage
808 packimage rhels7.3-x86_64-netboot-compute
1001 packimage -h
1002 history | grep packimage
[root@mgt ~]#
Another case would be the MEM size ,if the diskless image is 400MB ,than when
the image extract , it will be about 2GB , so it would be better to have 4G
memory for the diskless load

Subject: [xcat-user] stateless node: "no space left on device" when
loading/extracting rootimg
I'm sure this is a simple one, but I can't find the answer:
When booting my stateless node, the initrd loads without a problem, but
downloading the rootimg fails. My rootimage.tar.gz is 442 MB, a fairly normal
size as far as I can tell.
The error message is actually "no such file or device" but I already determined
that the real problem is that the root file system in the initrd is too small
to hold the rootimg.tar.gz.
When I strip down the rootimg.tar.gz to the bare minimum (363 MB), the download
completes, but extracting the image fails with an error "no space left on the
device".
How do I generate an initrd with more space in the root fs?
Here is my osimage :
Object name: rhels7.4-x86_64-netboot-hpccn
exlist=/install/custom/netboot/rh/hpccn.rhels7.4.x86_64.exlist
imagetype=linux
osarch=x86_64
osdistroname=rhels7.4-x86_64
osname=Linux
osvers=rhels7.4
otherpkgdir=/install/post/otherpkgs/rhels7.4/x86_64
otherpkglist=/install/custom/netboot/rh/hpccn.rhels7.4.x86_64.otherpkgs.pkglist
partitionfile=/install/custom/netboot/rh/hpccn.rhels7.4.x86_64.cfglocaldisk
permission=755
pkgdir=/install/rhels7.4/x86_64
pkglist=/install/custom/netboot/rh/hpccn.rhels7.4.x86_64.pkglist
postinstall=/install/custom/netboot/rh/hpccn.rhels7.4.x86_64.postinstall
profile=hpccn
provmethod=netboot
rootimgdir=/install/netboot/rhels7.4/x86_64/hpccn
synclists=/install/custom/netboot/rh/hpccn.rhels7.4.x86_64.synclist
And here is how I generate the image:
/opt/xcat/bin/genimage rhels7.4-x86_64-netboot-hpccn
/opt/xcat/sbin/packimage --method=tar rhels7.4-x86_64-netboot-hpccn
Thanks!
