Hi Qiu, Could you please elaborate on what you mean by disk expansion? We currently have support for quiescent pool expansion by adding new storage node(s). Are you considering adding new SSDs to an e

For the record, we also have a python script to estimate the amount of SCM vs NVMe required for a given middleware/object distribution. See https://github.com/daos-stack/daos/tree/master/src/vos/stora

Hi Shohei, I have just tried fio-3.19 with the dfs engine against both DAOS 1.2 (using UUIDS) and master (using UUIDs and labels) and couldn’t reproduce. Could you please check the pool UUID with dmg

Hm, I wonder whether I broke something with my latest fio upstream patch. Could you please try to revert commit 2819492b94f9ef901178e6972e0e5784ef3a8be9 locally, rebuild fio and retry? Thanks in advan

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 there, The fio numbers look indeed pretty low. Could you please tell us more about the configuration? It sounds like you have Optane pmem on all the nodes, right? How many DIMMs per node? How many
