Recently in the NFS, found that ordinary Shared directory can be normal after mount and access to content, but if the Shared directory mounted equipment directory, cannot access, specific as follows:
Assuming the NFS Shared directory is/data/WWW - data, and then in the test directory is a directory,
Through the
Dd if=/dev/zero of=loop. Dat bs=1 m count=20 create a file, and will mount this file to the/data/WWW - data/test directory
The client then over NFS mount/data/WWW - data, access to the original/data/WWW - data/test directory, rather than the mapped to loop disk content

Ask this question should be how to solve!

CodePudding user response:

Look, you take/data/WWW - data/test mapping out to look at, direct mount NFS/data/WWW data/test
