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 Sudhir Menon 2017-08-11 09:27:58 UTC 
Description of problem: ipa server uninstall with -v option displays "IOError: [Errno 9] Bad file descriptor Logged from file ipautil.py, line 442"


Version-Release number of selected component (if applicable):
ipa-server-4.5.0-21.el7_4.1.x86_64

How reproducible:Always


Steps to Reproduce:
1. Install IPA server
2. Uninstall ipa-server using the verbose option

#ipa-server-install --uninstall -U -v

Actual results: The console log displays the below message.

1. Check the below section
ipa         : DEBUG    stderr=
ipa         : DEBUG    Removing service keytab: /etc/dirsrv/ds.keytab
ipa         : DEBUG    Removing service credentials cache
ipa         : DEBUG    Starting external process
ipa         : DEBUG    args=/usr/bin/kdestroy
ipa         : DEBUG    Process finished, return code=0
ipa         : DEBUG    stdout=
ipa         : DEBUG    stderr=Traceback (most recent call last):

  File "/usr/lib64/python2.7/logging/__init__.py", line 835, in flush
    self.stream.flush()
IOError: [Errno 9] Bad file descriptor
Logged from file ipautil.py, line 442
ipa         : DEBUG    runas=dirsrv (UID 389, GID 389)

=========

2. Check the traceback seen at the end of the uninstall section.
ipa         : DEBUG    Traceback (most recent call last):

    for _nothing in self._uninstaller(self.parent):

  File "/usr/lib/python2.7/site-packages/ipaserver/install/server/install.py", line 1160, in uninstall
    sys.exit(rv)
SystemExit: 0

Expected results: 

1. Although it doesn't seem to break anything, we should fix the above traceback seen.

2. Although the 'SystemExit: 0', if possible we should also fix the traceback to have a clean uninstall log file which doesn't confuse the end user.

Comment 3 Petr Vobornik 2017-08-18 16:33:09 UTC 
Was this already fixed upstream?
Comment 4 Standa Laznicka 2017-08-21 12:02:39 UTC 
This is fixed in FreeIPA master branch. A fix should arrive in RHEL 7.6 since the fix was a part of a major refactoring.

1. There are certain traceback's which are yet to be addressed e.g as mentioned in comment#2 hence reopening the bug.
