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.

Description Jan Safranek 2015-06-22 11:50:23 UTC 
With a MD RAID on the system, blivet.reset() fails with traceback:

  File "blivet_init.py", line 27, in <module>
    b.reset()
  File "/usr/lib/python2.7/site-packages/blivet/__init__.py", line 478, in reset
    self.devicetree.populate(cleanupOnly=cleanupOnly)
  File "/usr/lib/python2.7/site-packages/blivet/devicetree.py", line 2143, in populate
    self._populate()
  File "/usr/lib/python2.7/site-packages/blivet/devicetree.py", line 2209, in _populate
    self.addUdevDevice(dev)

    raise ValueError("device is already in tree")

Version-Release number of selected component (if applicable):
python-blivet-0.61.15.5-1.el7.noarch

How reproducible:
always

Steps to Reproduce:
1. create a MD RAID:
mdadm -C -l 1 -n 2 /dev/md/test /dev/vda{1,2}

2. run this small script:
   import blivet
   b = blivet.Blivet()
   b.reset()

Actual results:
traceback

Expected results:
no error

Additional info:
Reproducible in recent nightly, RHEL-7.2-20150618.n.0, i.e. after blivet rebase.
Comment 1 Jan Safranek 2015-06-22 11:50:54 UTC 
This is a regression since RHEL 7.1.
Comment 4 Brian Lane 2015-06-22 20:45:39 UTC 
Please attach the logs.
Comment 5 Jan Safranek 2015-06-23 07:52:43 UTC

blivet log (/dev/md127 = RAID1 vda1+vda2)

Adding logs. /dev/md127 (the problematic one) is RAID 1 composed of /dev/vda1 and /dev/vda2.
Comment 6 David Lehman 2015-06-23 14:05:40 UTC 
I have fixed this in my local 7.2 branch.
