Upstream issue: https://github.com/openshift/sriov-network-operator/issues/43

Comment 2 Peng Liu 2019-07-31 08:08:44 UTC

mstconfig requires 'rw' permission of sysfs. However in the container, the sysfs is mounted as 'ro'.

[root@dell-per740-14 /]# cat /proc/mounts | grep sysfs
sysfs /sys sysfs ro,seclabel,nosuid,nodev,noexec,relatime 0 0
sysfs /host/sys sysfs rw,seclabel,nosuid,nodev,noexec,relatime 0 0
sysfs /host/var/lib/containers/storage/overlay/e34d48d94d879727aec1bd4a768535d1ec72f8f20fbc9279ec750254717c2fca/merged/sys sysfs ro,seclabel,nosuid,nodev,noexec,relatime 0 0
