yum blocks when having blocking file systems

Description of problem:
We have systems where a file system (NFS) is unaccessible sometimes. Also there
are file systems wher root has no access and will not have ever.

In the later case we get just a "Permission denied" which is not nice but ok.
In the first case yum will block forever.

How reproducible:
- Mount a NFS filesystem from a remote server
- Switch off the remote server (or make it unavailable per iptables or other)
- Try to install/remove packages with yum

Actual results:
It blocks

Expected results:
No block

What could it do? What other programs don't fail in this way?

[Klaus (klaus-redhat-bugs)]

Ehem, That it clearly a bug.

There is no reason why yum should block when the filesystem is not releated to the path where to install.

Ok, I did forget to mention that I mean to have the NFS filesystem in (for example) /home/.../... or /net/... or somethink absolutelly unrelated to any path yum is needed to access.

To your question: I d not know any other program which fails this way.

So this IS a bug. And a grave one too.

[James (james-redhat-bugs)]

 So you have a path like:

/my/inaccessible/path

...and yum has problems with it? This only when installing/removing packages, yes?
 Does rpm work? As I seem to recall that rpm stats. mount points when it runs the transaction. So moving there, but it's NaB IMO or maybe a feature request.

[Panu (panu-redhat-bugs)]

Rpm in RHEL 6 only accesses and stat()'s paths actually relevant to the transaction, so it doesn't hang on unrelated things like NFS mounts. It's not backportable to RHEL 5 however due to the API changes involved.
