[All H13-629 Questions]

A Huawei OceanStor 9000 is externally shared using NFS and CIFS at the moment.

You want to set some parameters to improve the performance of the NFS mounted under the Linux operating system. Which of the following description is correct?

ARsize / wsize, read and write the maximum size of each block, it is recommended to adjust to the maximum. General Linux operating system environment, the maximum value of 1M.

BAsync, allowing asynchronous data write, synchronous write requirements. NFS server must brush each data into the hard disk before it can return success delay higher.

CNoatime, if you do not need to record the file access time, you can increase this parameter to avoid frequent access, modify the access time to open pin.

DNolock, if there is a shared file between NFS clients, you can use this parameter. Reduce service-side file lock overhead.

Wait, I thought Nolock could cause issues with file consistency?

I practiced a question about nolock before, and I think it helps with file locking issues, but I’m not clear on when exactly to use it.

Noatime sounds familiar; I believe it helps with performance by reducing unnecessary writes, but I’m not entirely sure how it works in practice.

I think async is a good option to improve write performance, but I’m a bit confused about the implications of using it.

I remember something about rsize and wsize being important for performance, but I'm not sure if 1M is the maximum for all setups.
