Red Hat Bugzilla 1506550 0 high CLOSED [downstream clone - 4.1.7] File missing after upgrade of RHVH node from version RHVH-4.1-20170925.0 to latest. 2021-02-22 00:41:40 UTC

Description Nikola Kresic 2018-05-08 07:47:18 UTC
Description of problem:
Very similar to the following bugzilla #1506550
Looks like a regression. Customer is updating the nodes, the network config files are old and created long time ago, never changed or edited, defroute=yes overwritten to defroute=no after update so that server hangs at boot until the defroute parameter is fixed manually.

Version-Release number of selected component (if applicable):
vdsm latest

How reproducible:
update from 4.17 to 4.19 tested, no idea if it hits other update paths

Steps to Reproduce:
1. one way
- Updated the host first from RHEVM: result was that avter VDSM Upgrade the host was unreachable.
- Previous SSH session was active 
- Set Host to Maintenance
- yum upgrade for rest of RHEL updates (kernel, etc.)
- Rebooted host
- Host not reachable via SSH
- From HW console: it is determined that there is no default route!!
- Set defroute=yes in /etc/sysconfig/network-scripts/ifcfg-rhevm
- service network restart
- Host is now activateable from RHEVM

2. second way
- Set host to maintenance
- yum upgrade
- reboot
- Host is not reachable via SSH
- On HW console again: no default route
- Edited /etc/sysconfig/network-scripts/ifcfg-rhevm, set defroute=yes
- service network restart
- Activate host in RHEVM

Actual results:
config file changed so that it breaks config

Expected results:
config file untouched during update, or at least not in a way that it breaks config

Would you please attach supervdsm.log from the time of the upgrade and first boot?

Comment 2 Jiri Belka 2018-05-22 11:37:03 UTC
can't reproduce, 3.6/el7.3 eus/els host to 4.1/el7.5:

# rpm -q vdsm kernel-$( uname -r ) initscripts redhat-release-server

both ifcfg-* and vdsm's chech file in /var/run/vdsm have yes for defroute.

putting host into maintenance and doing update:

# rpm -q vdsm kernel-$( uname -r ) initscripts redhat-release-server


# grep -i 'def.*route' /etc/sysconfig/network-scripts/ifcfg-ovirtmgmt 
[root@10-37-140-151 ~]# grep -iIR 'def.*route' /var/run/vdsm/ 2>/dev/null
/var/run/vdsm/netconf/nets/ovirtmgmt:    "defaultRoute": true

Comment 3 Jiri Belka 2018-05-22 11:38:33 UTC
We have already release 4.2, thus vdsm is 4.20.x now, could you try with 4.2?

Comment 4 Jiri Belka 2018-05-23 07:55:34 UTC
I upgraded also from 3.6 to 4.2 and it still works too.

Comment 5 Dan Kenigsberg 2018-06-24 07:21:37 UTC
Please reopen with the required logs. Please also include your /etc/vdsm/vdsm.conf
