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.

1st time won't fail anyway,
#virt-format -a virt_format.raw --filesystem=ext3 --lvm
try with the same device 2nd time, it will fail anyway,
#virt-format -a virt_format.raw --filesystem=ext3 --lvm

exit with 
/*format.c*/

Comment 1 Richard W.M. Jones 2013-01-21 08:53:45 UTC 
moli, I think this is a duplicate of bug 872831.

Furthermore, this works for me in RHEL 7 with:

libguestfs-1.20.1-6.el7.x86_64
util-linux-2.22.1-2.4.el7.x86_64

What version of util-linux do you have?  Can you try the
latest in RHEL 7 and see if that fixes the problem?

Comment 5 Richard W.M. Jones 2013-07-18 17:13:22 UTC 
WFM using:

libguestfs-1.22.2-1.el7.x86_64
util-linux-2.23.1-3.el7.x86_64

so it looks likely that whatever problem happened
with libguestfs/wipefs/util-linux has fixed itself.
Comment 7 bfan 2014-01-09 03:09:08 UTC 
Verified with libguestfs-tools-c-1.22.6-17.el7.x86_64

# virt-format -a virt_format.raw --filesystem=ext3 --lvm
# virt-format -a virt_format.raw --filesystem=ext3 --lvm
# 

Works well for trying twice
