Description Heinz Mauelshagen 2011-06-15 10:34:29 UTC
Description of problem:

dmraid doesn't support the new dm-raid456 device-mapper wrapping target by Neil Brown/Jon Brassow which offers access to the MD RAID personalities, thus trying to activate RAID5 mappings with the dm-raid456 target will fail.

Important!
The current support for the dm-raid45 target module supported in RHEL6 and other distros (which ain't go upstream) _must_ stay in for backward compatibility.

Version-Release number of selected component (if applicable):
dmraid-1.0.0.rc16-10.el6

How reproducible:
Always.

Steps to Reproduce:
1. Remove dm-raid45 target.
2. Have dm-raid456 target installed
3. Try activating any RAID5 set supported by dmraid (eg. isw)
  
Actual results:
Activation fails.

Expected results:
Activation succeeds.


Additional info:
THe enhancement involves additions to
lib/activate/activate.c
lib/events/libdmraid-events-isw.c
lib/metadata/metadata.c
lib/register/dmreg.c

Comment 3 RHEL Program Management 2012-07-10 06:49:23 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 4 RHEL Program Management 2012-07-10 23:06:32 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 5 RHEL Program Management 2012-09-07 05:21:34 UTC
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unable to address this
request at this time.

Red Hat invites you to ask your support representative to
propose this request, if appropriate, in the next release of
Red Hat Enterprise Linux.
