[lustre-discuss] [Lustre] How to remove stale mount in client?

[Trung Đặng Đinh Quốc]

Hello,

I am new to Lustre, and I just use it for my work.
During working with Lustre, I made a mistake when I unmount the file system.
After that, I think my Lustre client suffers from the previous stale mount.

This is the output of "*lfs check servers":*

What should I do in order to remove the stale subsystem (*ffff8c18cfdcd000*)
from my client?
Thank you very much.
