Hi there,

 Just started up node and it says  "Bang with message 'Reboot'". In my services under erp5, the instance is not loading and states that its "Looking for a free partition". I've already paid the 2 Euro's and paid shows as received. What am I missing?

Thanks for you help. 

As explained on the FAQ, several things can happen here:

  • you requested an instance of Software Release that is not available (not installed or no place left) in any node you have access to
  • you requested an instance of Software Release on a specific computer, but this computer can't accept this instance (software release not installed or no place left)


Normally the payment takes a while to be processed, normally they are processed in batch at midnight only. We are working to improve the speed of check payments. If you didn't do, please open a ticked from your account, the SlapOS master team may help you more.

As explained on the FAQ, several things can happen here:

  • you requested an instance of Software Release that is not available (not installed or no place left) in any node you have access to
  • you requested an instance of Software Release on a specific computer, but this computer can't accept this instance (software release not installed or no place left)



Am aware that am invoking a very old thread but thought it okay since it is a very similar issue.

I am facing the same problem of 'Looking for a free partition'. Have seen the FAQs -

I was following How to deploy SlapOS Master instance with SlapOS to install a master on my local network for experimental purposes via the 'slapos console' method. I started the process via Constantly saw the status - 'Looking for a free partition'. Then switched to  . Thereafter, thinking that to have this working I have paid up 2 EUR but yet the invoice is showing as ' Waiting for payment confirmation '.

 Now I have the following questions:

1. What could be the exact reason of the installation not progressing and how can I figure it out? The possible reasons given in the FAQ don't seem to be applicable in my scenario.

2. Is the payment validation still a mid-nightly batch process and should I expect this process to progress after that?

3. Or am I following a no longer supported method to get the SlapOS master running and thereafter ERP5? Please note that my aim is to assess if we can participate in ERP5 development and deployment.

Please do let me know if any further information shall be helpful to guide me.

Any guidance in this regards shall be highly appreciated.




Fisrt of all, thank you for using SlapOS platform. The message 'Looking for a free partition' mean that SlapOS Master couldn't allocate your requested instance. The possibles actions and responses for this problem can be found in our FAQ.

About deployment of SlapOS Master, the documentation your are using is outdated, we are updating our developer documentation and we didn't update this documentation yet, please read this documentation for the updated one.

The recommended procedure today to depoy SlapOS Master for development purpose is to request a webrunner then request SlapOS Master inside, this let you easily control your SlapOS Master instance through webrunner. You can follow this documentation to know how to request webrunner on Vifib platform. But you can still to the procedure of SlapOS Master installation in your own computer like your started before.

After you have requested your webrunner, go to "Menu" -> " Open Software Release" then select 'slapos-master' in software folder and open it. You can now click on the green button and inspect the result.

About questions:

1- If you still have the message 'Looking for a free partition' after you have paid the subscription invoice of 2 €, this can mean than your Software Release is not installed into the computer your are trying to use. You can request installation of Software Release from slapconsole with Supply command like in the documentation you are following for SlapOS Master deployment. Make sure that you have used the same computer Id (COMP-XXX) in your supply and request command.

If you compile software release from your own computer, you can also check log in folder /opt/slapos/log/slapos-node-software.log. If your instance is under deployment and is reporting errors, you can check log in : /opt/slapos/log/slapos-node-instance.log

2-  Normally the payment validation should not be so long. Please let us know how long it take to validate your payment so we can improve if it's needed. You can also create a tiket in / so we will have more information to correctly handle the problem.

3- It's great that you can  participate in ERP5 development and deployment, please try above procedure for SlapOS Master deployment and let us know if you have any issue.

Hi Alain,

Thanks a lot for your response.

I am trying the non-webrunner method first from But there seems to be something wrong.

This was my supply command-


software_url = ''

This was my request command -

import json
software_url = ''
# Choose a SlapOS Node

computer_id = 'COMP-2547'

But I see this in Home > My Space > My Services -> clicking on the service - #error while instanciating

Error while instansiating



And as you guided I have checked the log at /opt/slapos/log/slapos-node-instance.log which has this error which I have highlighted in red -

1. Can you please tell me what have I done incorrectly?

2. The payment issue is resolved and I see the invoice is now marked as Paid, hence I assume the account is now validated.

3. If I deploy my own slapos master, will I still be charged an amount of 2 EUR on a daily basis?

Look forward to your guidance.



And the log is filling up with the same message every minute. What do I need to terminate/clean-up and restart the process?

As per the discussion at,  I don't yet have the .completed file in /opt/slapgrid/bcb8fbfbae583c14297f14ec8ebc3724

However, I see that around 5 GB of files have been downloaded/created.

~# du -s /opt/slapgrid/bcb8fbfbae583c14297f14ec8ebc3724/*
200     /opt/slapgrid/bcb8fbfbae583c14297f14ec8ebc3724/bin

5012148 /opt/slapgrid/bcb8fbfbae583c14297f14ec8ebc3724/parts

So some action is happening but I am unable to make sense of it. Am not sure if I should do anything or simply wait till the .completed file is generated.

Any guidance on what I should do next shall be helpful.


1- About error message bellow:

IOError: Software Release is not correctly installed.
Missing file: /opt/slapgrid/bcb8fbfbae583c14297f14ec8ebc3724/instance.cfg

It mean that the software release is not correctly compiled. If compilation of sotware release fail, SlapOS will retry until it succeed. I think all you did was ok, but the SlapOS Master Software doesn't compile in your distro, it need to be fixed. In your case, you can get compilation error message with: tail -f /opt/slapos/log/slapos-node-software.log

Although SlapOS will retry to compile your software release to fix errors, if some file cannot be downloaded for example, the compilation will always fail. So you must check the log to make sure that Software can compile. Can you show what you have in your /opt/slapos/log/slapos-node-software.log ?

2- Yes, your instance is now start requested this mean that your account has been validated.

3- As your are deploying instance in your own server, you will only need to pay 1€ per month for instance subscription, if you have 2 instances, it will be 2 €, ...

Hi Alain,

I have uploaded the current log herein -

Please check and let me know.




SlapOS is failing to build OpenBLAS in your distro. We mostly test software releases on debian and CentoOS distribution. Which one are you using ?

Here is the error message:

Makefile.system:393: *** OpenBLAS: Cannot set both USE_OPENMP=1 and USE_THREAD=0. The USE_THREAD=0 is only for building single thread version.. Stop.

You are compiling from this version of openblas component:

Are you using a debian machine ? so I can try to reproduce the error.


Alain Takoudjou

Hi Shrenik,

I checked OpenBLAS's Makefile.system and found that USE_THREAD is overridden to 0 if it is built on a single core machine. I just added a patch so that USE_OPENMP should be also overridden to 0 in such case. 

I am using Ubuntu 14.04. Any suggestions to fix this on this OS itself?

Hi Kazuhiko,

Could you please guide me what I need to do with this patch to move ahead?

Do I need to manually apply it to the OpenBLAS module code and thereafter wait while the compilation auto-fixes?

Okay, I applied the changes as shared in the commit and the compilation seems to be progressing ahead for now.
