RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHEA-2011:1782 0 normal SHIPPED_LIVE new packages: vdsm 2011-12-06 11:55:51 UTC

Description Maor 2011-04-03 16:44:01 UTC 
Description of problem:
Right now ,to fetch specific file types from Iso domain, we use a specific verb for each file type like Iso or floppy.
As part of the new cache mechanism implementation for Iso domains in the backend side, The files are persisted in the DB,
so after this change, it would be a benefit, if VDSM will expose us a new API verb, which will get two parameters, 
one, the pool Id
second, the file type (code number).
(There will be support for a code that will retrieve all files types)

and will return a struct list, which will have the following parameters:
1. file size 
2. date created 
3. file type (which will be some kind of code).

By that, we can execute only one verb on the VDSM, that will fetch all the file types with the file type specified in the parameter.
Instead using many verbs, and getting list of Strings which will indicate the iso names or floppys.

Comment 2 RHEL Program Management 2011-04-04 02:04:39 UTC 
Since RHEL 6.1 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.
Comment 3 Igor Lvovsky 2011-04-10 11:48:42 UTC 
The new API was added to the vdsm to get files list from ISO domain: 
   
 getFileList(sdUUID, extension = None)

sdUUID  - Iso domain's UUID
extension - file's extension filter

To get whole file list, call  getFileList() without 'extension' parameter at all.


Return value:
 dictionary per file
   'files' : {'file1.vfd' : {'status': 0, 'ext': 'vfd', 
                              'ctime': 1302419597.5658536, 'size': 0},
              'file2.iso' : {'status': 0, 'ext': 'iso',
                             'ctime': 1302419597.5077033, 'size': 0}
             }

On host is python-2.6.6-20.el6.x86_64. When attempting to get the whole file list, I got this traceback that int exceeds XML-RPC limits.

If I use 'iso' or 'vfd' as extension, nothing is returned. There are some files on iso domain. In RHEVM files in iso are shown correctly.
