Red Hat Bugzilla – Bug 192081
dmsetup reports 0 opened devices on LVM2 volumes.
Last modified: 2007-11-30 17:07:25 EST
This customer is experiencing the same issues as reported back on January on
the dm-devel list:
The problem description:
After configuring LVM2 on top of a dm-raid device, dmsetup info will report its
usage counter is 0, not allowing the user to deactivate the volume.
Running: # dmsetup info -c stlinux12vg1-stlinux12vg1lv1
Returns: Open 0.
And running: # lvdisplay stlinux12vg1
Returns: open 1.
Then "vgchange -aln <vgname>" command will report :
Can't deactivate volume group "vgname" with 1 open logical volume(s)
There's a file describing all the customer has done attached to this Bugzilla
which, I believe, explains the issue command by command. Please let me know if
there is something missing,

Description of the problem.
As discussed, please re-test with the U3 packages.
If it's still wrong, add -vvvv to the lvdisplay command and post the full output.
