Hi,

please make sure that you are on CentOS 7.9,  your kernel level indicates that you may be on an older level?

Best,

Michael

I create the pool and container with POSIX type successfully. But I mount the dfs by dfuse failed and I get the error message as follow:
fuse: error: filesystem requested capabilities 0x10000 that are not supported by kernel, aborting.
My system is Centos 7 and the kernel is 3.10.0-957. I install the daos services by the yum repo.

Thanks a lot.

Yes that’s correct  – libioil requires the container to be dfuse-mounted. And note that all metadata operations will still go through dfuse, libioil only intercepts (most of) the data I/O calls.

Best,

Michael

OK, thanks. And I want to know if I must mount the dfuse before using the libioil interception library?

Thanks a lot.

Yes, libioil works in conjunction with DFuse and allows the interception of POSIX I/O calls.

OK, thanks. And I want to know if I must mount the dfuse before using the libioil interception library?

Thanks a lot.
