Greetings
We run ovs 2.17 on our stacks, and we use ovn through OVN-Kubernetes
I notice that when tracing a flow that goes through an ovn
loadbalancer, I get a "no live bucket" message, and ofproto/trace does
not give the full trace of the packet:
ovs-appctl ofproto/trace br-int
in_port=27,dl_dst=0a:58:0a:e1:18:01,dl_src=0a:58:0a:e1:18:09,tcp,nw_src=10.225.24.9,nw_dst=10.224.0.1,nw_ttl=60,tcp_dst=443
..
19. ct_state=+new+trk,tcp,metadata=0x30,nw_dst=10.224.0.1,tp_dst=443,
priority 120, cookie 0xb3a567e9
set_field:0/0x2000000000000000000000000->xxreg0
set_field:0xae000010000000000000000/0xffffffff0000000000000000->xxreg0
set_field:0x1bb00000000/0xffff00000000->xxreg0
group:399
-> no live bucket
this group matches a select that I can get from the ovn-controller:
# ovs-appctl -t /var/run/ovn/ovn-controller.8726.ctl group-table-list
| grep 399\$
type=select,selection_method=dp_hash,bucket=bucket_id=0,weight:100,actions=ct(nat(dst=10.64.245.116:6443),commit,table=20,zone=NXM_NX_REG13[0..15],exec(set_field:2/2->ct_mark)),bucket=bucket_id=1,weight:
100,actions=ct(nat(dst=10.64.245.20:6443),commit,table=20,zone=NXM_NX_REG13[0..15],exec(set_field:2/2->ct_mark)),bucket=bucket_id=2,weight:100,actions=ct(nat(dst=10.64.245.68:6443),commit,table=20,zone=N
XM_NX_REG13[0..15],exec(set_field:2/2->ct_mark)): 399
Would you know if there is a way to display the full trace when doing
ofproto/trace?
Cheers
