RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Harald Hoyer 2010-05-26 15:30:14 UTC 
Created attachment 416880 [details]
40-multipath.rules

Description of problem:
If a whole device is used for multipath, the underlying devices should have the partitions removed.

Please ship the attached 40-multipath.rules

This blocks bug 595719
Comment 2 Harald Hoyer 2010-05-26 17:14:44 UTC 
btw, if the multipath rules would be a little bit later (70 instead of 40), you could honor the udev environment variables and skip the scsi_id run.

Comment 3 Harald Hoyer 2010-05-27 16:15:07 UTC 
another optimization would also be only run "multipath -c" on non-partition devices.


SUBSYSTEM!="block", GOTO="end_mpath"
ENV{DEVTYPE}!="partition", \
   ENV{DM_MULTIPATH_DEVICE_PATH}!="1", \
   PROGRAM=="/sbin/multipath -c $tempnode", \
   ENV{DM_MULTIPATH_DEVICE_PATH}="1"

ENV{DM_MULTIPATH_DEVICE_PATH}=="1", \
   ENV{DEVTYPE}!="partition", \
   RUN+="/sbin/partx -d --nr 1-1024 $env{DEVNAME}"

RUN+="socket:/org/kernel/dm/multipath_event"

KERNEL!="dm-*", GOTO="end_mpath"
ACTION!="change", GOTO="end_mpath"
ENV{DM_SUSPENDED}=="1", GOTO="end_mpath"
ENV{DM_UUID}!="mpath-?*", GOTO="end_mpath"
ENV{DM_ACTION}=="PATH_FAILED", GOTO="end_mpath"
RUN+="$env{DM_SBIN_PATH}/kpartx -a -p p $tempnode"
LABEL="end_mpath"
Comment 4 Ben Marzinski 2010-05-28 22:45:37 UTC 
Unfortunately, I do need to check if multipath is in /sbin or /usr/sbin.  It's necessary for anaconda, and unless I'm working on a dm device, I can't use $env{DM_SBIN_PATH}. The ENV{MPATH_GOT_HERE} was just debuginfo information that never got deleted from the patch, but the rest (or something like it) is necessary.  Otherwise the patch seems reasonable.
Comment 5 Harald Hoyer 2010-06-10 16:17:15 UTC 
"/sbin/multipath -c" should only run on ACTION=="add"
Comment 6 Ben Marzinski 2010-06-16 23:30:27 UTC 
Here are the new rules:

SUBSYSTEM!="block", GOTO="end_mpath"

ENV{MPATH_SBIN_PATH}="/sbin"
TEST!="$env{MPATH_SBIN_PATH}/multipath", ENV{MPATH_SBIN_PATH}="/usr/sbin"

ACTION=="add", ENV{DEVTYPE}!="partition", \
        ENV{DM_MULTIPATH_DEVICE_PATH}!="1", \
        PROGRAM=="$env{MPATH_SBIN_PATH}/multipath -c $tempnode", \
        ENV{DM_MULTIPATH_DEVICE_PATH}="1"

ENV{DM_MULTIPATH_DEVICE_PATH}=="1", ENV{DEVTYPE}!="partition", \
        RUN+="/sbin/partx -d --nr 1-1024 $env{DEVNAME}"

RUN+="socket:/org/kernel/dm/multipath_event"
KERNEL!="dm-*", GOTO="end_mpath"
ACTION!="change", GOTO="end_mpath"
ENV{DM_SUSPENDED}=="1", GOTO="end_mpath"
ENV{DM_UUID}!="mpath-?*", GOTO="end_mpath"
ENV{DM_ACTION}=="PATH_FAILED", GOTO="end_mpath"
RUN+="$env{MPATH_SBIN_PATH}/kpartx -a -p p $tempnode"
LABEL="end_mpath"
Comment 7 Harald Hoyer 2010-06-17 08:10:59 UTC 
fine, this might work
Comment 8 Ben Marzinski 2010-06-19 02:15:44 UTC 
Done.
Comment 10 releng-rhel@redhat.com 2010-11-10 20:10:35 UTC
