If I bind it to a core (which seems odd?), the /sys error goes away,
but I still get the hugepages error:
% ./zbalance_ipc -i zc:enp4s0 -m 1 -n 12 -c 44 -g 1
- From strace:
socket(0x1b /* PF_??? */, SOCK_RAW, 768) = 3
setsockopt(3, SOL_IP, 0x87 /* IP_??? */, ",\0\0\0\0\0\0\0", 8) = 0
setsockopt(3, SOL_IP, 0x6e /* IP_??? */, "pfring-zc-cluster-44", 20) = 0
open("/proc/meminfo", O_RDONLY) = 4
fstat(4, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x7f05780b1000
read(4, "MemTotal: 16251784 kB\nMemF"..., 1024) = 1024
read(4, "Total: 0\nHugePages_Free: "..., 1024) = 202
read(4, "", 1024) = 0
close(4) = 0
munmap(0x7f05780b1000, 4096) = 0
write(2, " *** error retrieving hugepages "..., 41) = 41
close(3) = 0
write(2, "pfring_zc_create_cluster error ["..., 99) = 99
exit_group(-1) = ?
Anyone have any ideas? I'm trying to set up ZC so 12 snorts
can read from the ZC interface. Maybe I'm not doing it right?
