[Spacewalk-list] .treeinfo file missing and then trying squashfs.img

Wed May 30 08:37:32 UTC 2018

Hi Andreas,

Thanks a bunch for your reply

It seems that the .treeinfo file is imported when the distro was
created in the var/cache/rhn/reposync/1/ directory

####

[root at du-tst-spw-trn02 tftpboot]# find / -iname .treeinfo
/var/cache/rhn/reposync/1/rhel-74-iso/.treeinfo
/var/cache/rhn/reposync/1/repo-centos-7/.treeinfo
/var/www/html/pub/mnt/7.4/.treeinfo
/var/www/html/pub/mnt/c7/.treeinfo
/var/iso-images/mnt/7.4/.treeinfo

######

while the file .discinfo itself is not imported anywhere. I have no
easy way to check if the content is imported in the db somehow

Is there any other place this file should be as well ?

I guess the minimal way to PXE / kickstart a machine is

Create a Channel and then a repo. Sync the repo with the DVD to the
repo over http or file:/// with the command spacewalk-repo-sync and
the --sync-kickstart option
Then create a kickstart distribution over the locally mounted iso as
you described at all. Finally you create a kickstart profile. Finally
you make sure that dhcp is working and you next server is your tftp
server and the declaration in dhcpd.conf like

#####
group {
  next-server 10.131.101.19;
  host tftpclient {
# tftp client hardware address
 hardware ethernet  00:50:56:a3:1c:b9;
 filename "pxelinux.0";
     }
}
#######

In the /var/lib/tftpboot/images/ directory you find a dir named under
your distribution you have just created like
distribution-name:Org_Name . Inside that you find the vmlinuz and
inird.img which I hashed and verified they are the right ones.

Perhaps I am missing something. Feel free to rhrow me ideas (even
irrelevant) , I am sure I am missing something really basic here

Best,

Nikos
