Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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.

Comment 1 Peter Rajnoha 2013-12-19 11:04:23 UTC 
To test this issue, just create an MD with LVM on top of it, for example:

  mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda /dev/sdb
  pvcreate /dev/md0
  vgcreate vg /dev/md0
  lvcreate -l1 vg

Then try to reboot the system and check whether the lvm2-pvscan@<major>:<minor>.service is in active or inactive state (where the <major> and <minor> is the major and minor for the MD device). If the service is in loaded, but inactive state you're hitting the bug which also causes the LV to stay inactive (since the service that would activate it is not run properly).

You can check the state of the service by:
  systemctl status lvm2-pvscan@<major>:<minor>.service
  (or just grep for it: systemctl -a | grep lvm2-pvscan)

With the fix, the pvscan service should always be in active state when loaded.

Marking verified (SanityOnly). I saw no problems running the operations listed in comment #1 a few times.
