Hi Eeheet, You can use the fio DAOS engine (https://daos-stack.github.io/devbranch/admin/performance_tuning/#fio). If you want to stick to dfuse, then I would advise to use the posixaio engine instead

Hi, The DFS layer does not track openers, so the other client will be able to proceed and delete the file. The original opener will thus suddenly see an empty file. Please note that if the two process

Hi Peter, A few things to try/explore: I don’t think that we have ever tested with 2x pmem DIMMs per socket. Maybe you could try with dram instead of pmem to see whether the performance increases. 16x

Hi Lipeng, Assuming that you are using 1.2, you can create a POSIX container with the daos utility: $ daos cont create --pool <POOL_UUID> --type POSIX You get back a container UUID that you can then p

Hi there, We do run DAOS on a regular basis on Google cloud (GCP), but I am not aware of anyone who tried it on AWS yet. If that is something that you want to pursue, we would be happy to learn about

Hi, Maybe you have a firewall running on the VM? You could maybe try to run the containers with --network=host to use the host network. Please note that you will also have to open up ports 31416 and 3

Hi Kedar, I assume that you are passing event = NULL to daos_kv_put() and only have one operation in flight, right? In the “normal” case (i.e. no membership change, no restart), the bulk of the work h

Hi, The dmg format command actually connects to the server to initiate the format. In your case, the server failed to start, so the “refused connection” is expected. I assume that you are running the

Hi Ping, Right, no endpoint configuration on the client side, the agent fetches everything (except the access points and certificate) by connecting to the servers. Are you sure that you don’t have (in
