Re: [xcat-user] choosing kernel for genimage (xCAT 2.13.4)
The problem is gone now. I had originally done the chdef -t osimage -p pkgdir before there was a line for rhels7.3-x86_64-netboot-comp_kup. It created a new entry for me with most of the fields blank. There was no rootimg dir, and there had been no pkgdir before I ran the command. Therefore there was nothing to append the new pkgdir to. I went back and cloned an existing line for rhels7.3-x86_64-netboot-comp (with our earlier customizations), then did chdef -t osimage rhles7.3-x86_64-netboot-comp_kup -p kerneldir <...> The result was kerneldir was filled in, and pkgdir was also prepended with the kernel directory. I think this is what was intended in the documented example. I ended up with a bootable image, and the correct kernel/initrd. Thanks for the help, your solution was much simpler than what I was thinking it would take. -- ddj > On Dec 3, 2018, at 8:57 PM, Yuan Y Bai wrote: > > Hi David, > > Thanks you pointing out that the doc is not clear about "kerneldir", and make > you confused about "kerneldir" and "pkgdir". > > Here you should use "pkgdir" to append kernels repo directory into pkgdir. > Here is my example, could you try like this, if you have problems, contact me > freely. > > ]# ls /install/kernels/3.10.0-860.el7.x86_64/ > dracut-033-535.el7.x86_64.rpm > dracut-network-033-535.el7.x86_64.rpm > kernel-3.10.0-860.el7.x86_64.rpm > linux-firmware-20180220-62.git6d51311.el7.noarch.rpm > repodata > > ]# chdef -t osimage rhels7.3-x86_64-netboot-compute -p > pkgdir=/install/kernels/3.10.0-860.el7.x86_64 > > ]# lsdef -t osimage rhels7.3-x86_64-netboot-compute -i pkgdir > Object name: rhels7.3-x86_64-netboot-compute > pkgdir=/install/rhels7.3/x86_64,/install/kernels/3.10.0-860.el7.x86_64 > > ]# genimage rhels7.3-x86_64-netboot-compute -k 3.10.0-860.el7.x86_64 > > ]# packimage rhels7.3-x86_64-netboot-compute > > > > > Best Regards > -- > Yuan Bai (白媛) > > CSTL HPC System Management Development > Tel:86-10-82451401 > E-mail: by...@cn.ibm.com > Address: IBM ZGC Campus.

Re: [xcat-user] choosing kernel for genimage (xCAT 2.13.4)
Hi David, Thanks you pointing out that the doc is not clear about "kerneldir", and make you confused about "kerneldir" and "pkgdir". Here you should use "pkgdir" to append kernels repo directory into pkgdir. Here is my example, could you try like this, if you have problems, contact me freely. ]# ls /install/kernels/3.10.0-860.el7.x86_64/dracut-033-535.el7.x86_64.rpmdracut-network-033-535.el7.x86_64.rpmkernel-3.10.0-860.el7.x86_64.rpmlinux-firmware-20180220-62.git6d51311.el7.noarch.rpmrepodata ]# chdef -t osimage rhels7.3-x86_64-netboot-compute -p pkgdir=/install/kernels/3.10.0-860.el7.x86_64 ]# lsdef -t osimage rhels7.3-x86_64-netboot-compute -i pkgdirObject name: rhels7.3-x86_64-netboot-compute pkgdir=/install/rhels7.3/x86_64,/install/kernels/3.10.0-860.el7.x86_64 ]# genimage rhels7.3-x86_64-netboot-compute -k 3.10.0-860.el7.x86_64 ]# packimage rhels7.3-x86_64-netboot-compute Best Regards--Yuan Bai (白媛)CSTL HPC System Management DevelopmentTel:86-10-82451401E-mail: by...@cn.ibm.comAddress: IBM ZGC Campus.

Re: [xcat-user] choosing kernel for genimage (xCAT 2.13.4)
The document seems to have a problem with the examples — the description talks about “kerneldir” attribute, but the example uses “pkgdir”. When I use pkgdir it clobbers the existing value (/install/rhels7.3/x86_64) with new value (/install/kernels/3.10.0-862.14.14.el7.x86_64) I think it should say chdef -t osimage <> -p kerneldir=<> I got further using that format. However, I’m still having trouble with the packimage command “Error: Cannot find rhels7.3-x86_64-neboot-comp_kup from the linuximage table.
