Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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 of problem:
In a disk pool, when try to create a volume on a disk on which no primary partition is available, virsh vol-create command will fail.
Version-Release number of selected component (if applicable):
libvirt-0.8.1-8.el6.x86_64
# uname -a
Linux dhcp-66-70-6.nay.redhat.com 2.6.32-33.el6.x86_64 #1 SMP Thu Jun 3 13:00:03 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux
How reproducible:
Always
Steps to Reproduce:
1. Prepare a disk pool xml:
# cat pool-disk-test.xml
<pool type='disk'>
<name>sda</name>
<source>
<device path='/dev/sda'>
</device>
</source>
<target>
<path>/dev</path>
</target>
</pool>
2. define the disk pool
# virsh pool-define pool-disk-test.xml
Pool sda defined from pool-disk-test.xml
3. Start the pool
# virsh pool-start sda
Pool sda started
4. Check the current disk info:
# virsh pool-dumpxml sda
<pool type='disk'>
<name>sda</name>
<uuid>b0f38663-5d3f-1dd6-36eb-0fb86e7314a6</uuid>

4. Try to create a vol in the pool
# cat vol-partition-test.xml

# virsh vol-create sda vol-partition-test.xml
error: Failed to create vol from vol-partition-test.xml
error: internal error '/sbin/parted /dev/sda mkpart --script primary 58185630720B 58290488319B' exited with non-zero status 1 and signal 0: /sbin/parted: invalid token: primary
Actual results:
virsh vol-create command always try to create a primary partition.
I try to specify "logical" format for the partition in xml, but looks like the command can not recognize "logical".
...
<target>
<path>/dev/sda9</path>
<format type='logical'/>
</target>
...
# virsh vol-create sda vol-partition-test.xml
error: Failed to create vol from vol-partition-test.xml
error: XML description for unknown volume format type logical is not well formed or invalid
Expected results:
User should be successful to create logical partition on the disk where no primary partition is available.
