add_partition() does not initialize a partition's read-only policy field, so it defaults to 0, or read-write, even if the disk itself is flagged read-only. If a partition is detected after the call to set_disk_ro() (which sets each partition's policy field), the partition can be writable, even though the disk itself is not. This is known to happen with s390 DASD disks, but could potentially impact other disk drivers as well. A simple patch to make the partition inherit the disk's policy field was accepted upstream and is in the 2.6.18 kernel: http://marc.theaimsgroup.com/?l=linux-kernel&m=115192926219558&w=2 committed in stream U5 build 42.18. A test kernel with this patch is available from http://people.redhat.com/~jbaron/rhel4/ 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. QE ack for RHEL4.5. 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-2007-0304.html |
