4 years ago Hi,
Could you share your NUMA configuration - an output from command numactl --hardware? Do you have configured PMEM NUMA node correctly? See https://pmem.io/2020/01/20/memkind-dax-kmem.html for details. Do you have installed memkind which supports automatic detection of PMEM NUMA node? Before building and installing libmemkind from sources, please ensure that you have libdaxctl-devel (v66 or later) installed on your machine.
You could quickly test Redis you build to ensure your machine is configured correctly with:
- make MALLOC=memkind CFLAGS=-DREDIS_TEST
- ./redis-server test pmem

Hi!
I'm trying to use only the PMEMs but when I change the configuration file (redis.conf) to "only-pmem" at line 1788 I get the following error. Have you encountered this issue before?
I built the project on a centos 8 machine using the memkind allocator.
Thanks Adam
