I am trying to get ZC up and running on Oracle Enterprise Linux 7 (Linux ord12-v-sec-cap-05 3.10.0-229.11.1.el7.x86_64 #1 SMP Wed Aug 5 13:40:15 PDT 2015 x86_64 x86_64 x86_64 GNU/Linux) using the latest version of pf_ring.
I have licenses for both of my interfaces. I have installed the pf_ring and ZC ixgbe driver. I've tried running zsend on one of my ZC capable interfaces, but I get the following: ./zsend -i zc:enp48s0f0 -c 1 -g 0 -b 8 -l 60 pfring_zc_create_cluster error [No buffer space available] Please check your hugetlb configuration My hugepages config is: sysctl -a | grep huge vm.hugepages_treat_as_movable = 0 vm.hugetlb_shm_group = 0 vm.nr_hugepages = 32 vm.nr_hugepages_mempolicy = 32 vm.nr_overcommit_hugepages = 0 cat /proc/meminfo | grep Hugepagesize Hugepagesize: 1048576 kB I would think that 32 x 1 GB hugepages would be enough. On the file system, they are mounted: mount | grep huge cgroup on /sys/fs/cgroup/hugetlb type cgroup (rw,nosuid,nodev,noexec,relatime,hugetlb) hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime) nodev on /mnt/hugepages type hugetlbfs (rw,relatime) Any thoughts as to what I am doing wrong here.? Thx. C
