DESCRIPTION

Information about a Linux operating system image that can be used to deploy cluster nodes.


linuximage Attributes:

imagename

The name of this xCAT OS image definition.

template

The fully qualified name of the template file that is used to create the kick start file for diskful installation.

pkglist

The fully qualified name of the file that stores the distro packages list that will be included in the image.

pkgdir

The name of the directory where the distro packages are stored.

otherpkglist

The fully qualified name of the file that stores non-distro package lists that will be included in the image.

otherpkgdir

The base directory where the non-distro packages are stored.

exlist

The fully qualified name of the file that stores the file names and directory names that will be excluded from the image during packimage command. It is used for diskless image only.

postinstall

The fully qualified name of the script file that will be run at the end of the packimage command. It is used for diskless image only.

rootimgdir

The directory name where the image is stored. It is used for diskless image only.

kerneldir

The directory name where the 3rd-party kernel is stored. It is used for diskless image only.

nodebootif

The network interface the stateless/statelite node will boot over (e.g. eth0)

otherifce

Other network interfaces (e.g. eth1) in the image that should be configured via DHCP

netdrivers

The ethernet device drivers of the nodes which will use this linux image, at least the device driver for the nodes' installnic should be included

kernelver

The version of linux kernel used in the linux image. If the kernel version is not set, the default kernel in rootimgdir will be used

krpmver

The rpm version of kernel packages (for SLES only). If it is not set, the default rpm version of kernel packages will be used.

permission

The mount permission of /.statelite directory is used, its default value is 755

dump

The NFS directory to hold the Linux kernel dump file (vmcore) when the node with this image crashes, its format is ``nfs://<nfs_server_ip>/<kdump_path>''. If you want to use the node's ``xcatmaster'' (its SN or MN), <nfs_server_ip> can be left blank. For example, ``nfs:///<kdump_path>'' means the NFS directory to hold the kernel dump file is on the node's SN, or MN if there's no SN.

crashkernelsize

the size that assigned to the kdump kernel. If the kernel size is not set, 256M will be the default value.

comments

Any user-written notes.

disable

Set to 'yes' or '1' to comment out this row.
