Description of problem: ifup-ib in rdma-core-22.4-5.el7.x86_64 or later always shows error messages wrongly like [root@sandy01 network-scripts]# ifup ib0 ERROR : [/etc/sysconfig/network-scripts/ifup-ib] Error setting device ib0 MTU to 1500, using HW default. What's wrong is only the error messages. MTU is set as specified succesfully. [root@sandy01 network-scripts]# ip link show ib0 4: ib0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN mode DEFAULT group default qlen 256 link/infiniband 80:00:02:08:fe:80:00:00:00:00:00:00:00:02:c9:03:00:f9:2a:51 brd 00:ff:ff:ff:ff:12:40:1b:ff:ff:00:00:00:00:00:00:ff:ff:ff:ff Version-Release number of selected component (if applicable): # rpm -qf /etc/sysconfig/network-scripts/ifup-ib rdma-core-22.4-5.el7.x86_64 How reproducible: static IP address for ib0 is better. Because DHCP logic is more complicated. Steps to Reproduce: 1. ifdown ib0 2. ifup ib0 3. Actual results: functional but with message like ERROR : [/etc/sysconfig/network-scripts/ifup-ib] Error setting device ib0 MTU to 1500, using HW default. Expected results: functional without any message as long as ifup is successful Additional info: - Originally, we found this problem in centOS7.8. And we reported this problem to https://bugs.centos.org/view.php?id=17851 bugs.centos.org adviced us to report this problem to bugzilla.redhat.com. - We also checked following RPMs and ifup-ib in them are identical. cent7.8/rdma-core-22.4-1.el7_8.x86_64.rpm cent7.8/rdma-core-22.4-2.el7_8.x86_64.rpm cent7.8/rdma-core-22.4-4.el7_8.x86_64.rpm cent7.9/rdma-core-22.4-5.el7.x86_64.rpm - Since rdma-core-22.4-1.el7.x86_64 in 7.8.2003, /etc/sysconfig/network-scripts/ifup-ib] in rdma-core-22.4-1.el7.x86_64 was modified. - We want to focus on secstion for setting ib0's MTU. 127 if [ -n "${MTU}" ]; then 128 ip link set dev ${DEVICE} mtu ${MTU} 129 if [ "$?" ]; then 130 net_log $"Error setting device ${DEVICE} MTU to ${MTU}, using HW default." 131 fi 132 fi return value should be treated more carefully like [root@sandy01 network-scripts]# diff ifup-ib.sstc ifup-ib 129c129 < if [ "$?" -gt 0 ]; then --- > if [ "$?" ]; then - even return value is 0, the if [$? ] is true.
(In reply to sstcosaka from comment #0) > What's wrong is only the error messages. > MTU is set as specified succesfully. First of all, I admit the wrong message is annoy. The problem is that rhel-7.9 is the last RHEL7 release. We have to file z-stream bug to fix this. To file a z-stream bug, business justification MUST be provide. So, this minor bug is unlikely get approved. > return value should be treated more carefully like > [root@sandy01 network-scripts]# diff ifup-ib.sstc ifup-ib > 129c129 > < if [ "$?" -gt 0 ]; then > --- > > if [ "$?" ]; then The patch looks good. I'm closing this bug as WONTFIX in next week. Please let me know if you can provide business justification for this bug before I close it.
