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 Nenad Peric 2013-10-14 12:39:54 UTC 
Description of problem:

When a RADI1 is converted to thinpool, device mapper spews an error, which is not fatal, but makes very little sense

How reproducible:

Everytime 

Steps to Reproduce:

[root@virt-013 ~]# vgcreate vg /dev/sd{a..f}1
  No physical volume label read from /dev/sdd1
  Physical volume /dev/sdd1 not found
  No physical volume label read from /dev/sdf1
  Physical volume /dev/sdf1 not found
  Physical volume "/dev/sdd1" successfully created
  Physical volume "/dev/sdf1" successfully created
  Volume group "vg" successfully created
[root@virt-013 ~]# lvcreate --type raid1 -L4G -n raid1 vg
  Logical volume "raid1" created
[root@virt-013 ~]# lvconvert --thinpool vg/raid1
  Logical volume "raid1_tmeta" created
  Logical volume "lvol0" created
  device-mapper: remove ioctl on  failed: Device or resource busy
  Converted vg/raid1 to thin pool.


Expected results:

Not seeing a message which looks as if something went wrong, when the conversion actually finished successfully.

Comment 1 Zdenek Kabelac 2013-10-14 12:48:01 UTC 
This error message is related to deactivation of thin pool metadata spare device which is zeroed and deactivated - this should be handled in 2.02.102 via new udev rules flags.
Comment 3 RHEL Program Management 2013-10-18 02:25:20 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
