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 Corey Marthaler 2017-05-17 15:09:21 UTC 
Description of problem:
This does not appear to affect raid1. All others are affect however.

The following types (raid4,5,6,10,0) were created on a rhel4 machines, deactivated, then scanned on the rhel7.3 machine and attempted to be activated. 


# rhel7.3

# raid4 and raid5 issues all looked like this:

May 17 09:41:51 harding-02 kernel: device-mapper: ioctl: error adding target to table



# raid0, raid6 and raid10 issues all looked like this:

[root@harding-02 ~]# lvchange -ay activator1
  device-mapper: create ioctl on activator1-lvol0_rmeta_0LVM-rk2rZRu5Mgu6E1tdM5EVbCur3AqKTgllds9gwmRiK556cN8hD7WMV08fotasb6hn failed: Device or resource busy

Comment 2 Zdenek Kabelac 2017-05-17 15:27:46 UTC 
This is 'different' case.

You get 'unknown' segtype - so this case is working fine.
Comment 3 Alasdair Kergon 2017-05-18 14:46:32 UTC 
So something is missing from the new metadata to identify it as not-possible-to-activate on the old systems.

Once again, all the cases need to be identified, and then the metadata changed.  Also need to check the new userspace code checks the running kernel version correctly. (I.e. 7.4 userspace booted with a 7.3 kernel should not show this problem.)

Comment 7 Corey Marthaler 2017-06-23 22:37:58 UTC 
Looks like we still have raid4 issues on 7.3 w/ 7.4 created raid volumes. Everything (except for raid0 obviously) works on 7.2 though. Are we fine with raid4 errors remaining for verification?
