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.

Comment 10 Mike Burns 2010-08-13 19:41:47 UTC 
I've tried to work around the issue in RHEV-H, but it doesn't appear possible.  I've escalated bz 623846 to be a blocker for RHEL 6 because of this.
Comment 11 Mike Burns 2010-08-13 20:32:25 UTC 
Moving to rhev-hypervisor to track inclusion of package with fix in it. No code change should be necessary.
Comment 12 Denise Dumas 2010-08-16 21:10:26 UTC 
623846 is in Mod and will be picked up in tonight's nightly compose to enable pre-Snapshot sanity-checking on Tuesday.
Comment 16 Mike Burns 2010-08-17 20:39:25 UTC 
This BZ is being closed since it is fixed by the parted bz and no actual changes need to be made on ovirt-node/rhev-h side.

Comment 17 Alan Pevec 2010-08-20 12:07:31 UTC 
See bug 624781 comment 4 and 6,
there still seems to be inconsistency between /dev/mapper/ and underlying sd* block devices.
Comment 18 Alan Pevec 2010-08-20 12:19:22 UTC 
Here's example:

[root@localhost /]# grep parted /live/isolinux/manifest-srpm.txt 
parted-2.1-10.el6.src.rpm

[root@localhost /]# multipath -l /dev/sda  
0QEMU    QEMU HARDDISK   drive-scsi0-0-1 dm-3 QEMU,QEMU HARDDISK
size=2.0G features='0' hwhandler='0' wp=rw
`-+- policy='round-robin 0' prio=-1 status=active
  `- 0:0:1:0 sda 8:0  active undef running
[root@localhost /]# parted /dev/dm-3 print
Model: Linux device-mapper (multipath) (dm)
Disk /dev/dm-3: 2147MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start  End     Size    Type     File system  Flags
 1      512B   256MB   256MB   primary  ext2
 2      257MB  512MB   255MB   primary  ext2
 3      512MB  2147MB  1636MB  primary               lvm

[root@localhost /]# parted /dev/sda print
Error: /dev/sda: unrecognised disk label

So we need workaround from bug 623846 comment 14:
[root@localhost /]# echo 3 > /proc/sys/vm/drop_caches
[root@localhost /]# parted /dev/sda print
Model: QEMU QEMU HARDDISK (scsi)
Disk /dev/sda: 2147MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start  End     Size    Type     File system  Flags
 1      512B   256MB   256MB   primary  ext2
 2      257MB  512MB   255MB   primary  ext2
 3      512MB  2147MB  1636MB  primary               lvm

It also wouldn't hurt to align partition boundaries to 1M.

Comment 26 Vivian Bian 2010-08-26 07:14:51 UTC 
checked with rhev-hypervisor-6.0-13 

[ prerequisite ]
A clean machine with no HostVG created 

Steps to Reproduce:
1.Configure rhev-h through firstboot without shared root, and make root + HostVG on the same disk 
2.Choose "Local Install and Reboot"

actual result :
after installation can't boot 

[root@localhost ~]# ll /dev/disk/by-label/
total 0
lrwxrwxrwx. 1 root root 10 Aug 26 07:04 CONFIG -> ../../dm-8
lrwxrwxrwx. 1 root root 11 Aug 26 07:04 DATA -> ../../dm-10
lrwxrwxrwx. 1 root root 10 Aug 26 07:04 LOGGING -> ../../dm-9

lrwxrwxrwx. 1 root root  9 Aug 26 07:12 rhev-hypervisor -> ../../sr0

There is no partition named Root , RHEVH can't find grub to boot . 


So set bug status to ASSIGNED

Comment 37 Vivian Bian 2010-09-03 05:16:36 UTC 
checked with rhev-hypervisor-6.0-13.1 

steps :
1. partition without shared root on SATA, virtio disk , FC LUN , CCISS disk 
2. install locally and reboot 

actual result :
after installation could boot from SATA, virtio disk , FC LUN , CCISS disk 

So set bug status to VERIFIED
