Re: Fio with I/O Engine=DFS


Lombardi, Johann
 

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 pool list and also send me the output of dmg pool query --pool $PUUID?

 

Cheers,

Johann

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 advance.

 

Cheers,

Johann

Hi Johann,

Thank you. Here is an example how I set POOL and CONT env vars to. Yes, I'm using DAOS 1.2 and fio version fio-3.27-84-gf7942.

[Setting Env Vars]
 export POOL=4a6fa2f6-f2aa-40d5-9092-63ea46641887
 export CONT=1ed2c63e-9c20-4746-9ec4-03ce57c5d5a2 

[FIO Version]
fio --version
fio-3.27-84-gf7942

Thank you very much,

Shohei
