Description RamaKasturi 2019-02-04 07:20:37 UTC
Describe the Issue: rr_weight "uniform" line is missing in the section of adding contents to /etc/multipath.conf after upgrading gluster pods.

SetionName & Number : 7.3 && Upgrading Client on RedHatOpenShiftContainerPlatform Nodes

Suggestions For Improvement : content of /etc/multipath.conf should be something as below.

# LIO iSCSI
devices {
        device {
                vendor "LIO-ORG"
                user_friendly_names "yes" # names like mpatha
                path_grouping_policy "failover" # one path per group
                hardware_handler "1 alua"
                path_selector "round-robin 0"
                failback immediate
                path_checker "tur"
                prio "alua"
                no_path_retry 120
                rr_weight "uniform"
        }
}

Comment 7 RamaKasturi 2019-03-19 07:15:52 UTC
Verified in 3.11 docs from the link provided at comment 5 and i see that the line rr_weight "uniform" is present the contents of /etc/multipath.conf file.

Verified in 3.10 docs from the pdf provided at comment 6 and i see that the line rr_weight "uniform" is present in the contents of /etc/multipath.conf file.

Moving the bug to verified state as the contents are present in both the docs.
