Hello All,
I am not sure what exactly happened, but it definitely seems like
threading issue went wrong. I was importing a distro and during that
time, I also added a system, but the newly added system was not using
the currently importing distro or profile. The import bombed out with
memory corruption error. Then I tried to recover but found that I kept
getting traceback errors whenever i ran any cobbler command. I have
rebooted, and still cobbler is not able to run now. Before I blow
away my installation and try again any suggestions?
Hmmm .... Cobbler isn't threaded. Were you using the WebUI and command
line at the same time? Ordinarily that should be ok, though if one
were to crash (still not sure why it actually crashed?) while it had not
yet finished writing the configuration file, that would be a problem.
Do you have a copy of the error (traceback) you could post?
Part of the goodness about the new serializer (which very well could
become the default) is it should solve the problem of the any sort of
error occuring while cobbler is writing the configuration file. With
the yaml format, cobbler has to rewrite it's entire configuration file
when you save a new object, so if it runs out of disk space. The new
serializer is able to insert only the changes.
Yes, I would delete your existing
/var/lib/cobbler/(distros|profiles|systems|repos) files and let cobbler
regenerate them. If you want to back up this directory
(/var/lib/cobbler) periodically, it would probably be a good idea.
Here is the full traceback:
