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
Can not create NFS storage in rhevm

version
VDSM client:
# rpm -qa libvirt qemu-kvm-rhev vdsm kernel seabios
qemu-kvm-rhev-0.12.1.2-2.317.el6.x86_64
seabios-0.6.1.2-25.el6.x86_64
libvirt-0.10.2-5.el6.x86_64
kernel-2.6.32-330.el6.x86_64
vdsm-4.9.6-39.0.el6_3.x86_64
RHEVM:
# rpm -qa rhevm; uname -r
rhevm-3.1.0-22.el6ev.noarch
2.6.32-330.el6.x86_64

How reproducible:
100%

Steps
1. Build a RHEVM environment, register a VDSM client to RHEVM.

2. Configure a NFS server.

3. New a NFS domain in RHEVM using the NFS server you just created.

Failed with error:
Error while executing action New NFS Storage Domain: Error creating a storage domain

4. Check RHEVM /var/log/ovirt-engine/engine.log, get error info:

Comment 23 Ayal Baron 2012-11-07 14:43:59 UTC 
From bug 873855 : "Description of problem:
VDSM doesn't use recommended alignment and buffer size and this can cause a segmentation fault in new kernels"
Comment 25 EricLee 2012-11-22 05:17:53 UTC 
I can not reproduce this bug with the packages:
# rpm -qa libvirt qemu-kvm-rhev kernel vdsm
qemu-kvm-rhev-0.12.1.2-2.330.el6.x86_64
kernel-2.6.32-338.el6.x86_64
libvirt-0.10.2-9.el6.x86_64
vdsm-4.10.2-1.0.el6.x86_64
And can create NFS storage domain successfully(with V3 as the default nfs Version in RHEVM GUI).

Testing this bug with RHEV-H 6.4 Snapshot 4 build fails to either create or attach NFS export domains.

Relevant section of vdsm log is attached.

Comment 28 gaoshang 2013-01-21 08:59:51 UTC 
This bug blocked RHEVH+RHEVM(vdsm/rhevm mode) host/guest association acceptance testing, need to be fixed ASAP.
Comment 29 haiyang,dong 2013-01-23 03:06:40 UTC 
Test versions:
rhev-hypervisor6-6.4-20130116.3.0.auto1412.el6.iso
vdsm-4.10.2-1.2.el6.x86_64

After add rpcbind service into this auto rhev-h 6.4 build,register rhevh into rhevm si ,then NFS storage domains can be attached successfully now. About "Miss /etc/init.d/rpcbind service in rhev-h 6.4" issue, review bug 902677.
Comment 30 Allon Mureinik 2013-01-23 10:10:37 UTC 
According to comments below, this seems to have been fixed.
Moving to ON_QA to verify it.
Comment 31 gaoshang 2013-01-25 12:53:44 UTC 
This bug still exist in rhevh 6.4 snapshot5 [1], failed to create NFS storage in rhevm and can not find /etc/init.d/rpcbind service.

[root@hp-dc5850-02 ~]# service rpcbind status
rpcbind: unrecognized service


Our host/guest association acceptance testing are still blocked, but virt-who Errata testing needs to complete before EOB of Jan 30, hope it can be fixed ASAP.
