Re: [foreman-users] Re: "No root file system is defined" error using preseed atomic partitioning scheme

[Akash Kaveti]

Hey Hauke,

I am using Preseed default template for partition table, in it using Crypto 
method for my hardware encryption.
Is there any way I can give a default password for it, so that I shouldn't 
give password during the installation?

Thank you.

It's always hard to guess what device is getting used.
If you have a usb-stick plugged-in with the e.g. a formean-boot-iso,
that might be /dev/sda and your "real" hard-disk might be /dev/sdb/.

In that case "head -n2" will do the trick.
When using raid-devices this might be different too.

Re: [foreman-users] Re: "No root file system is defined" error using preseed atomic partitioning scheme

[Akash Kaveti]

Hello Again,

It is working now, I have check the syslog, the device I am trying to 
install is not there it seems,
so I gave /dev/sdb, it is working now.

I am trying to install ubuntu by unattended installation on a hardware box.
I am using the default the partition template, I am not using LVM.
 
It is working for the current host, but what about the other hosts, Why 
cant I use "*d-i partman/early_command string debconf-set partman-auto/disk 
"$(list-devices disk | head -n1)*"

Thank you for the help, i have been struggling with this error from 
yesterday.

Re: [foreman-users] Re: "No root file system is defined" error using preseed atomic partitioning scheme

[Hauke Behrens]

Hi,

what kind of system are you trying to install to ?
KVM/Libvirt, a hardware box, something else ?
Are you maybe using LVM to provide the virtual disk ?

Please provide some more information on what you are trying to install
to. Maybe that will help to find the error.

I've also seen that error before, and in my cases it always was:
"trying to install to a wrong disk or "trying to install to non-
existant device".

One thing you can try is to switch to a different console
(ctrl+alt+f1,f2 etc.) during the install and checking syslog, to see
what commands are issued.
Check if the device really exists on the system or try another recipe.

Hauke

[foreman-users] Re: "No root file system is defined" error using preseed atomic partitioning scheme

[Akash Kaveti]

Hi,

Thanks for the response, I have tried to install on different server as 
well, but got the same error,
Below I am pasting my partition template,



# Use the first detected hard disk as default installation disk
#d-i partman/early_command string debconf-set partman-auto/disk 
"$(list-devices disk | head -n1)"
d-i partman-auto/disk string dev/sda

### Partitioning
# The presently available methods are: "regular", "lvm" and "crypto"
d-i partman-auto/method string crypto

# If one of the disks that are going to be automatically partitioned
# contains an old LVM configuration, the user will normally receive a
# warning. This can be preseeded away...
d-i partman-lvm/device_remove_lvm boolean true
# The same applies to pre-existing software RAID array:
d-i partman-md/device_remove_md boolean true
# And the same goes for the confirmation to write the lvm partitions.
d-i partman-lvm/confirm boolean true
d-i partman-lvm/confirm_nooverwrite boolean true


# You can choose one of the three predefined partitioning recipes:
# - atomic: all files in one partition
# - home:   separate /home partition
# - multi:  separate /home, /var, and /tmp partitions (/usr was removed in 
jessie)
d-i partman-auto/choose_recipe select atomic


# If you just want to change the default filesystem to something
# else, you can do that without providing a full recipe.

# This makes partman automatically partition without confirmation, provided
# that you told it what to do using one of the methods above.
d-i partman/confirm_write_new_label boolean true
d-i partman/choose_partition select finish
d-i partman/confirm boolean true
d-i partman/confirm_nooverwrite boolean true

Thank you.

Re: [foreman-users] Re: "No root file system is defined" error using preseed atomic partitioning scheme

[Hauke Behrens]

Hi,

the problem probably isn't the partitioning schema itself, but the disk
used/defined before.

Check if this part

"d-i partman-auto/disk string /dev/vda"

matches your server.

Maybe some other value is needed for your case, like /dev/sda/ or /dev/xvda.

You can override that in the partition table itself or by adding an
according host.param for install_disk.

The relevant snippet is this one:

<% if @host.params['install-disk'] -%>
d-i partman-auto/disk string <%= @host.params['install-disk'] %>
<% else -%>
d-i partman-auto/disk string /dev/vda
<% end -%>


Hope it helps,

Hauke

[Akash Kaveti]

Exact error message is, No root file system is defined, Please correct this 
form partitioning menu. 
I have installed foreman with DHCP in a network, where I have disabled the 
existing DHCP in that Network.
