Description

The algorithm should not have allocated new parts of the mirror onto the same PV as an existing log. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. Patch is posted to linux-lvm: https://www.redhat.com/archives/linux-lvm/2006-August/msg00098.html I think the contiguous part of this got fixed. Fixed in 2.02.10. Fix going into RHEL 4.5 Jon and I verified that the following mirror extend cases all worked: 1. mirror extend into contiguous free space on both m leg devices 2. mirror extend into non-contiguous free space on both m leg devices 3. mirror extend into non-contiguous free space on primary m leg but contiguous free space on secondary m leg An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2007-0287.html |
