Hello everyone, I’m enabling DPDK on a system and I don’t see any errors while doing so. However, after enabling DPDK, I can see that my system has way less free hugepages than expected. It should only be using 512 at that point but it’s using 1914. OvS is the only potential candidate that can be consuming hugepages at that time. I tried to verify that it is indeed OvS that is allocating these hugepages by checking each process under /proc/<proc-id>/smaps but surprisingly I did not find any process having hugepages under its process ID. I wonder if there is something failing internally in OvS that is messing up the hugepage allocation.
Here are a few details of the system I’m using: OvS version: 2.17.3 DPDK version: 21.11.0 Kernel version: 4.18.0-372.9.1.el8.x86_64 HugePages_Total: 5120 HugePages_Free: 3206 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB Hugetlb: 10485760 kB I noticed that the OvS and DPDK versions are not precisely matching with the official support listed here: https://docs.openvswitch.org/en/latest/faq/releases/ Could that be a reason for this behavior? I’ve attached the log files of the ovs-vswitchd.log of the time where DPDK gets enabled to this email. Thanks for any help!
