Description

HI,

i try to create an iso image in this way :

[root@foo.foo public]# foreman-rake bootdisk:generate:host NAME=host.foo.it OUTPUT=/var/lib/foreman/public/host --trace

Invoke bootdisk:generate:host (first_time)
Invoke environment (first_time)
Execute environment
Execute bootdisk:generate:host
I: -input-charset not specified, using utf-8 (detected in locale settings)
Size of boot image is 4 sectors -> No emulation
Total translation table size: 2048
Total rockridge attributes bytes: 0
Total directory bytes: 0
Path table size(bytes): 10
Max brk space used 0
328 extents written (0 MB)

Ensure the host host.foo.it exists. Ensure the directory is writeable by foreman user. Add missing ISO extension:

foreman-rake bootdisk:generate:host NAME=host.foo.it OUTPUT=/tmp/test.iso

Hi,
The directory /var/lib/foreman /var/lib/foreman/public are both writeable by foreman user and the host.foo.it exist (i create and i see it on the web interface).

The production log and the command output are the same as in the previous message.

[root@foreman_server public]# foreman-rake bootdisk:generate:host NAME=host.foo.it OUTPUT=/var/lib/foreman/public/host.foo.it --trace

Invoke bootdisk:generate:host (first_time)

I don't know what is wrong in your case, but this is the command that fails:

https://github.com/theforeman/foreman_bootdisk/blob/master/app/services/foreman_bootdisk/iso_generator.rb#L78

Locate that line, add some print debug (Rails.logger.info "XXX") and print whole command, block tempdir from being deleted and then issue that command manually and try to find what is wrong.

This works out of box without problems.

The command

foreman-rake bootdisk:generate:host NAME=host.foo.it OUTPUT=/var/lib/foreman/public/host.foo.it --trace

should work only if the host is in "build mode" ? because if the host isn't in "build mode" the output is the same.

Yes must be in build mode. By the way, when you download the same disk from UI, does it work? If it does, workaround might be to use API/hammer CLI to get the ISO.
