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 Martin Krajnak 2015-12-07 15:12:57 UTC 
Description of problem:
RHEL6 cannot detect LVM created on two flashdisks in RHEL7. gnome-disk-utility shows only two flashdisks, no LVM partitions are present.

Version-Release number of selected component (if applicable):
kernel-2.6.32-573.el6.x86_64
udisks-1.0.1-9.el6.x86_64
gnome-disk-utility-2.30.1-3.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1.create LVM in RHEL7
2.reboot to Rhel6
3.open gnome-disk-utility

Actual results:
No LVM partition are present

Expected results:
LVM partitions should be present and possible to mount 

Additional info:
Output for udisks --dump on RHEL6:

Comment 1 Tomas Smetana 2016-04-11 07:35:05 UTC 
Hi,
  it is highly unlikely this will ever get fixed in RHEL-6. However:

Does RHEL-7 udisks2 (or some  mount the flash disks correctly?
Can you mount the LVM partition by the standard CLI tools (not udisks) in RHEL-6?

Thanks and regards.
Comment 2 Martin Krajnak 2016-04-13 11:56:01 UTC 
yes, it is possible,
after connecting devices with lvm run as root:

$vgscan
  Reading all physical volumes.  This may take a while...
  Found volume group "vol_grp1" using metadata type lvm2
#vgchange -a y
  3 logical volume(s) in volume group "vol_grp1" now active

then you can mount logical volumes:

mount /dev/vol_grp1/logical_vol1 /mnt/vol1/
mount /dev/vol_grp1/logical_vol2 /mnt/vol2/
mount /dev/vol_grp1/logical_vol3 /mnt/vol3/

tested on 6.8
Comment 3 Tomas Smetana 2016-04-20 10:15:23 UTC 
OK. So if the flash disks are plugged into another system (not the one they were created on), does gnome-disks find them? No matter which OS...
Comment 4 Tomas Smetana 2016-04-25 12:05:39 UTC 
I was not able to make this work (automatically recognizing LVM on a flash drive) well even under a recent Fedora. I seriously don't think anybody is going to implement the LVM support in the ancient RHEL-6 udisks.

I think WONTFIX is actually appropriate in this case.
