Description

I'm trying to migrate MoinMoin from 1.5.8 to 1.8.0. My current meta file inside the data_dir contains this information:

data_format_revision: 1059999

After executing the second phase of the migration this message is output to stdout:

New rev is 1060000.

Then it crashes with this exception:

Traceback (most recent call last):
  File "/usr/bin/moin", line 6, in ?
    run()
  File "/usr/lib/python2.4/site-packages/MoinMoin/script/moin.py", line 15, in run

    self.mainloop()

EnvironmentError: Could not lock in MetaDict

Do not migrate and keep using 1.5.8

Discussion

Looks like a file accessing write problem. Is that filesystem full or don't you have accessrights?

• Not it's not full (32% used). I'm running the script as root, so no access problems neither.

Plan

• Priority:
• Assigned to:
• Status: worked on a different system without problem, maybe some weird installation problem
