Description

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. 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. 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. Heinz, please check if this feature is already in RHEL6. (We believe it is already in RHEL7.) 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).
