Hello! I'm switching to Debian 8 from Debian 7 and found very interesting bug with your load_driver.sh (ixgbe).
./load_driver.sh rmmod: ERROR: Module ixgbe is not currently loaded Warning: 0 hugepages available, 1024 requested irqbalance: no process found Configuring eth6 no rx vectors found on eth6 no tx vectors found on eth6 eth6 mask=1 for /proc/irq/112/smp_affinity Configuring eth7 no rx vectors found on eth7 no tx vectors found on eth7 eth7 mask=1 for /proc/irq/114/smp_affinity Configuring eth4 no rx vectors found on eth4 no tx vectors found on eth4 eth4 mask=1 for /proc/irq/108/smp_affinity Configuring eth5 no rx vectors found on eth5 no tx vectors found on eth5 eth5 mask=1 for /proc/irq/110/smp_affinity As you can see load_driver.sh tried to allocate 1024 huge pages but failed (maybe you should fail in this case?). This issue related with allocated by default in Debian 8 hugetlb buffers: AnonHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 74240 kB DirectMap2M: 50255872 kB But there are no allocated pages: grep HugePages_Total /sys/devices/system/node/node0/meminfo I suggest following fix for load_driver.sh: if [ `cat /proc/mounts | grep hugetlbfs | wc -l` -eq 0 ]; then sync && echo 3 > /proc/sys/vm/drop_caches echo $HUGEPAGES > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages mkdir /mnt/huge mount -t hugetlbfs nodev /mnt/huge else echo $HUGEPAGES > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages fi After this fix everything loaded correctly: ./load_driver.sh rmmod: ERROR: Module ixgbe is not currently loaded rmmod: ERROR: Module pf_ring is not currently loaded Configuring eth6 no rx vectors found on eth6 no tx vectors found on eth6 eth6 mask=1 for /proc/irq/112/smp_affinity Configuring eth7 no rx vectors found on eth7 no tx vectors found on eth7 eth7 mask=1 for /proc/irq/114/smp_affinity Configuring eth4 no rx vectors found on eth4 no tx vectors found on eth4 eth4 mask=1 for /proc/irq/108/smp_affinity Configuring eth5 no rx vectors found on eth5 no tx vectors found on eth5 eth5 mask=1 for /proc/irq/110/smp_affinity ######################################################################### # ERROR: You do not seem to have a valid PF_RING ZC license 6.0.3.150330 for eth4 [Intel 10 Gbit ixgbe 82599-based] # ERROR: Please get one at http://shop.ntop.org/. ######################################################################### # We're now working in demo mode with packet capture and # transmission limited to 5 minutes ######################################################################### libnuma: Warning: node 6 not allowed numa_sched_setaffinity_v2_int() failed; abort : Invalid argument set_mempolicy: Invalid argument ######################################################################### # ERROR: You do not seem to have a valid PF_RING ZC license 6.0.3.150330 for eth4 [Intel 10 Gbit ixgbe 82599-based] # ERROR: Please get one at http://shop.ntop.org/. ######################################################################### ######################################################################### # ERROR: You do not seem to have a valid PF_RING ZC license 6.0.3.150330 for eth4 [Intel 10 Gbit ixgbe 82599-based] # ERROR: Please get one at http://shop.ntop.org/. ######################################################################### ^CLeaving... ========================= Absolute Stats: 0 pkts - 0 bytes ========================= -- Sincerely yours, Pavel Odintsov _______________________________________________ Ntop-misc mailing list Ntop-misc@listgateway.unipi.it http://listgateway.unipi.it/mailman/listinfo/ntop-misc
