What Engine version is it? Does the bug show up when you are editing non-management network? Hi Dan engine version is provided in description and bug verson ^^ 3.5.7-0.1.el6ev No, only for management network. Can you attach super,vdsm,connectivity.log as well? Did Vdsm persist the new config? Created attachment 1106693 [details]
vdsm logs
It seems that vdsm is not persist the new config --> 'rhevm': {'addr': '10.35.128.19', 'bootproto4': 'none', 'bridged': True, 'cfg': {'BOOTPROTO': 'none' [root@pink-vds2 ~]# cat /var/lib/vdsm/persistence/netconf/nets/rhevm {"nic": "enp4s0", "mtu": "1500", "bootproto": "dhcp", "STP": "no", "bridged": "true", "defaultRoute": true} [root@pink-vds2 ~]# cat /var/run/vdsm/netconf/nets/rhevm {"nic": "enp4s0", "ipaddr": "10.35.128.19", "mtu": "1500", "netmask": "255.255.255.0", "STP": "no", "bridged": "true", "gateway": "10.35.128.254", "defaultRoute": true} Attaching logs. Important thing i didn't mentioned, the operation cause the server to become non responsive for few seconds, host and engine loosing connectivity for few seconds. does the bug show up with engine-3.5.6 and new Vdsm? An engine-3.5.7 and and old Vdsm? I don't have a clue were the regression may lie (Engine/Vdsm) lowering severity as editing management network is not recommended anyway. Hi Dan, The bug doesn't show up in engine 3.5.6 and vdsm 3.5.7. Managed to reproduce in engine 3.5.7 with older vdsm versions like : vdsm 4.16.30-1.el7ev.x86_64 and 4.16.28-1.el7ev.x86_64 (reproduced not 100%) Dan, please note, that this report no longer 100 reproducible, because i had several attempts which succeeded. But it is still failing in 60-70% of the attempts. Alona, is there anything new in Engine-3.5.7 that might have triggered this bug? Development Management has reviewed and declined this request. You may appeal this decision by reopening this request. Alona has verified that nothing has changed since ovirt-3.5.6 that could have triggered this bug. Moreover, as it reproduces very inconsistently, we believe it is not a regression. It seems like an issue that has been lurking since the introduction of jsonrpc, and should be fixed with bug 1277988 which would stop Engine's change of jsonrpc connection during setupNetworks command. I do not believe this issue is urgent enough to merit entry to 3.5.8, hence my devel_ack-. |
