---------------------------------------
Summary: IGFS: Do not allow DUAL -> PRIMARY -> DUAL modes
interleaving.
Key: IGNITE-3405
URL: https://issues.apache.org/jira/browse/IGNITE-3405
Project: Ignite
Issue Type: Bug
Components: IGFS
Affects Versions: 1.6
Reporter: Vladimir Ozerov
Assignee: Ivan Veselovsky
Priority: Critical
Fix For: 1.7
Currently we allow almost any combinations of path modes. This appears to be
wrong. Consider the following scenario:
1) /dir1 -> PRIMARY
2) /dir1/dir2 -> DUAL
It is impossible to support this scenario properly because {{dir1}} will be
created in both file systems anyway, but primary and secondary representation
will be "detached" from each other.
Instead, we should allow only DUAL -> PRIMARY and DUAL -> PROXY transitions.
Any other combinations doesn't make sense.
