Ruby on Rails could not be started>class variable @@platform

[hufter]

Though my hda was initially working flawlessly, Ruby on Rails does not start since a few weeks. This happened after one of my drives filled up to 99%, though it does not belong to the greyhole storage pool. So perhaps this is unrelated.

Anyhow, Rails does not start, so the control panel is inaccessible. I tried recommendations from several other posts such as reinstalling rails 2.3.4, removing rack 1.1.0 (I also tried removing 1.0.1 and keeping 1.1.0), reinstalling hda-platform. Nothing worked.

Now my error message (see below) is slightly different from other Ruby on Rails problems. The message suggests that the real problem lies with hda platform. However, I do not have the slightest idea how to solve this and I would prefer not to reinstall hda because of custom settings.

Any help? Please find the output of Phusion Passenger below.

If your root drive is full, this could be a result of that. Once you clear out some space, a restart might fix things.

[hufter]

There is plenty of space in the root partition, and there always has been. Still Rails won't start, and I do not know how to solve it. The steps mentioned in several forum threads do not work here.

I am convinced the fault lies somewhere else, for example with the platform variable mentioned in the error message. Any help?

I hope this provides enough information for Linux cracks to solve this problem. Otherwise, I will probably have to uninstall Amahi and call it a day.

I have removed Amahi and changed my server into a Vortexbox music server. I manually added Greyhole, so it doubles as a file server, and this really rocks.
