Confirmed this in RHEL 5.3 (Tikanga). My system here is doing the same thing; each time I run mkinitrd on my system it sets the "mkrootdev..." line to use sd[a|b|c|d] instead of the correct MPATH variable. The 'resume' line gets set properly with the multipath listed, but not the mkrootdev line. Making the simple change that Jean-Francois in the mkinitrd script causes mkinitrd to create an initrd file with the correct 'mkrootdev...' line in it using the multipathed root. 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. Jean and Adam, Red Hat QE may not be able to test this particular setup. Are you willing to test if this feature is fixed and provide feedback during RHEL 5.6 test campaign (i.e. when we release a Beta or a snapshot)? It is OK for me *** This bug has been marked as a duplicate of bug 503567 *** |
Description of problem: In the script mkinitrd, the variable rootdev is overwritten when the multipath is activated that leads to have the wrong rootdev to create the line "mkrootdev -t ext3 -o defaults,ro /dev/sdc" instead of mkrootdev -t ext3 -o defaults,ro /dev/VolGroup00/LogVol01" In the mkinitrd line 1135 if [ "${withmpath}" -eq "1" ]; then for rootdev in ${rootdevs} ; do <== Overwrite the rootdev variable disk=$(find_dm_in_sysblock ${rootdev} | sed -e 's,^/sys,,') wwid=$(/sbin/scsi_id -g -u -s ${disk}) if [ -z "${wwid}" ]; then # Could be EMC unit requiring special option wwid=$(/sbin/scsi_id -g -ppre-spc3-83 -u -s ${disk}) fi if [ -n "${wwid}" ]; then case " ${root_wwids} " in *" ${wwid} "*) continue ;; *) root_wwids="${root_wwids} ${wwid}" ;; esac fi done if [ -n "$root_wwids" ]; then use_multipath=1 fi fi Version-Release number of selected component (if applicable): mkinitrd-5.1.19.6-28 How reproducible: when multipath is activated for boot on SAN Steps to Reproduce: 1. ~/mkinitrd -f initrd-2.6.18-92.1.6.el5.img 2.6.18-92.1.6.el5 Actual results: The system can't boot with the initrd generated by this script Expected results: Boot the system on SAN with the correct initrd Additional info: In the mkinitrd line 1135 rename the variable rootdev by rootdev1 in the following line solve this problem if [ "${withmpath}" -eq "1" ]; then for rootdev1 in ${rootdevs} ; do <== Overwrite the rootdev variable disk=$(find_dm_in_sysblock ${rootdev1} | sed -e 's,^/sys,,') wwid=$(/sbin/scsi_id -g -u -s ${disk}) if [ -z "${wwid}" ]; then # Could be EMC unit requiring special option wwid=$(/sbin/scsi_id -g -ppre-spc3-83 -u -s ${disk}) fi if [ -n "${wwid}" ]; then case " ${root_wwids} " in *" ${wwid} "*) continue ;; *) root_wwids="${root_wwids} ${wwid}" ;; esac fi done if [ -n "$root_wwids" ]; then use_multipath=1 fi fi
