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 Alasdair Kergon 2012-04-20 19:00:26 UTC 
Make dm-striped bug 814820 available through lvm.
Comment 1 RHEL Program Management 2012-07-10 08:25:41 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.
Comment 2 RHEL Program Management 2012-07-10 23:57:27 UTC 
This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development.  This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4.
Comment 3 Tom Lavigne 2012-09-07 15:21:57 UTC 
This request was evaluated by Red Hat Product Management for 
inclusion in the current release of Red Hat Enterprise Linux.
Since we are unable to provide this feature at this time,  
it has been proposed for the next release of 
Red Hat Enterprise Linux.
Comment 4 Jonathan Earl Brassow 2015-10-15 14:36:28 UTC 
Heinz, please check if this feature is already in RHEL6.  (We believe it is already in RHEL7.)
Comment 5 Heinz Mauelshagen 2015-10-16 08:21:21 UTC 
It is not in upstream.
It is not in RHEL7 either.

Obviously it is not as important to the original requester (xfs?).

FWIW: non-power of 2 stripe sizes are incompatible with md, thus
      once we support takeover from striped -> raid0/raid4/raid5,
      non-power of 2 striped mappings ain't supported to be taken
      over to those dm-raid mappings; conversion by duplication will
      be possible though (i.e. lvm creating a new LV with the requested
      layout and sync the content of e.g. the striped LV across).
