Bourreau could not be started: cgroup_entry (LoadError)

[DaveMtl]

Hi, I'm setting up a development environment on a local machine and I get an error when starting the Bourreau.

[2020-09-04 12:30:20 EDT] Remote control command for my_bourreau_app failed.
Command: cd /home/cbrain/cbrain/Bourreau; bundle exec ruby /home/cbrain/cbrain/Bourreau/script/cbrain_remote_ctl start -e development -p 1026 2>&1

As suggested in #265, I tried changing the version of proctable in the Gemfile of Bourreau to:

gem "sys-proctable", :git => 'git://github.com/djberg96/sys-proctable.git', :ref => "ac047b6"

but the error remained, (I did run the command bundle install).

Since the Bourreau and BrainPortal runs on the same machine, I also tried to change it in the Gemfile of BrainPortal but then BrainPortal won't start because it can't find cgroup_entry...

Have you tried the following:

  bundle show sys-proctable
  (copy the directory shown)
  cd /to/that/directory
  rake install

Source: https://github.com/aces/cbrain/wiki/Common-Setup#iv-gems

[prioux]

Yeah, that was my first suggestion. The Sys::Proctable gem requires a manual installation step that can cause exactly that problem if it's skipped.

First, cd to the Bourreau subdirectory then type bundle show sys-proctable; it will tell you where the bundler installed the gem. Go there, and run 'rake install`.

[DaveMtl]

Thanks for the fast answer.

I still have the same problem after trying the solution.

Maybe I just missed another step. I'll try reinstalling from scratch and see if works better.

[prioux]

cgroup_entry.rb is just one of the ruby files in the sys-proctable gem, it seems weird that it can't load it after installation.

[DaveMtl]

Sorry for closing the issue, that was a misclick...

I'm not familiar with Ruby and I had a few hiccups while following the installation so I might have done something I shouldn't have. I'll let you know how it goes after trying again.

Thanks for the help.

[DaveMtl]

Hi again,

I reinstalled everything from scratch and still have the same problem:

Any other suggestions?

[prioux]

OK, I'm going to suggest some more 'clean up and try again' commands. You can type the following commands exactly as they are, they don't need any adjustments.

These commands only attempt to clean up the gems directories, they won't affect the CBRAIN codebase itself.

cd  /home/cbrain/cbrain/BrainPortal
bundle clean --force

cd /home/cbrain/cbrain/Bourreau
bundle clean --force

cd  /home/cbrain/cbrain/BrainPortal
rm Gemfile.lock
gem uninstall sys-proctable
bundle install
cd $(bundle show sys-proctable)
rake install

cd /home/cbrain/cbrain/Bourreau
rm Gemfile.lock
bundle install
cd $(bundle show sys-proctable)
rake install

[DaveMtl]

Thanks again,

I get the same error:

Some remarks: In BrainPortal, bundle clean --force didnt return anything. In Bourreau, bundle clean --force returned:

Something I forgot to mention is that I had to add gem "thin" to the Gemfile of BrainPortal. The server wasn't starting without it.

Hi, I managed to start the Bourreau by copying the content of the proctable folder from: ~/.rvm/gems/ruby-2.4.1/gems/sys-proctable-1.2.6/lib/linux/sys to: ~/.rvm/rubies/ruby-2.4.1/lib/ruby/site_ruby/2.4.0/sys

For some reason, the install location of the bundle for Bourreau isn't the same as the location used at run time.

I don't know if it's related but when I run the command rake cbrain:plugins:install:all I get the message: No public assets need to be installed for a Bourreau All done. I thought it was odd the command didn't do anything.

[natacha-beck]

I think this one can be closed ? @bryancaron ?
