Trying to test hosted-engine on EL7, I got the following Traceback in VDSM:

 Thread-52::ERROR::2014-07-30 11:09:28,688::task::866::Storage.TaskManager.Task::(_setError) Task=`a041a63b-ef51-4352-98de-c5169bf8dcf1`::Unexpected error

Storage is NFSv3 on a different host.

Comment 3 Allon Mureinik 2014-09-02 07:29:48 UTC
Saggie, do we have an ioprocess build available on EL7?

Comment 5 Barak 2014-09-21 15:20:33 UTC
There is an available package for ioprocess for EL7,
This should be handled by storage group , moving back to storage.

BTW the initial error is "No such file or directory" ...

Comment 6 Yoav Kleinberger 2014-09-28 11:32:53 UTC
Is this an engine running on a RHEL7 VM, or an engine running on any VM operating system, but the *host* is running RHEL7?

I'm pretty sure you meant the host, but I want to be sure.

Comment 7 Artyom 2014-09-28 11:45:07 UTC
Reporter is Sandro so the best way it ask him, but how I understand host is EL7.
Also hard to understand when it happen, on what stage, on deployment of hosted engine or when hosted-engine deployment already finished, Sandro can you give a little more details about the flow, when exception appear, what actions preceded.

Comment 8 Sandro Bonazzola 2014-09-29 05:59:09 UTC
This is ovirt-hosted-engine-setup running on EL7 for creating a VM where it would have been installed EL 6.5 + RHEV-M 3.5 (but it failed before creating the VM)

It failed at Volume creation stage, after having created the storage domain:

2014-07-30 11:09:28 DEBUG otopi.context context._executeMethod:152 method exception

    raise RuntimeError(response["status"]["message"])

There are full logs of the setup execution and corresponding vdsm logs in the attached archive.

Comment 9 Sandro Bonazzola 2014-10-02 12:32:21 UTC
I'm not able to reproduce the issue using upstream rpms,maybe we should move this to QE as test-only so it can be checked on next downstream build?

I finish deployment for vt4 and not encounter this kind of exception, but all vdsm logs full of:

So I can reassign this bug or just open one new, what you prefer?

The two issues seem unrelated - please open a new BZ.

Comment 14 Artyom 2014-10-06 07:54:21 UTC
Verified on vdsm-4.16.5-2.el7.x86_64 and ovirt-hosted-engine-setup-1.2.0-1.el7.noarch
