问题
After aborting an import-process I wound up with a corrupt database. Reading nodes with a certain label almost always throws an error:
"Unable to load one or more relationships from Node[160147]. This usually happens when relationships are deleted by someone else just as we are about to load them."
The said node is a superconnected one with lots of relations. I cannot delete it nor it's relationships (using cypher) as it throws the same error. This happened in version 2.1.0, however öI have since updated to 2.1.2 in a futile hope the issue would be resolved.
Can I delete the node from the filesystem somehow or how can I salvage this?
Stack below.

回答1:
For consistency checking your datastore check out Mark's great blog post.
回答2:
What kind of import process did you abort how? If it was batch-inserter, then there are no guarantees on consistent stores if you abort it and you'll probably safer redoing your import.
If it was transactional there shouldn't be inconsistencies.
Please also note that 2.1.0 had some issues and shouldn't be used, so you might run into double issues there.
