I currently have zbalance_ipc configured with two instances per cluster id.
Normally, one would access the virtual device as “zc:10@0†and “zc:10@1â€.
I have n2disk capturing off of zc:10@0 instance. Unfortunately, when
trying to run nprobe against zc:10@1 instance it only occasionally works.
When it fails, I get the following error:
16/Mar/2016 19:42:24 [nprobe.c:5348] Using packet capture length 9000
16/Mar/2016 19:42:24 [util.c:4344] ERROR: Cannot get hw addr for zc:10@1
16/Mar/2016 19:42:24 [pro/pf_ring.c:356] Initializing PF_RING socket on
device zc:10@1..
16/Mar/2016 19:42:24 [nprobe.c:5424] ERROR: Unable to open interface
zc:10@1.
16/Mar/2016 19:42:24 [nprobe.c:7080] ERROR: Unable to open interface zc:10@1
(zc:10@1: No such device exists (SIOCGIFHWADDR: No such device))
16/Mar/2016 19:42:24 [nprobe.c:7082] ERROR: Try using -i none if you do not
want capture from a NIC
The fix seems to be a complete restart of the pf_ring service.
Any advice on what to look at next?
