nfs:nfs_shrinkreaddir

Description

Some older NFS servers might incorrectly handle NFS version 2 READDIR requests for more than 1024 bytes of directory information. This problem is due to a bug in the server implementation. However, this parameter contains a workaround in the NFS version 2 client.

When this parameter is enabled, the client does not generate a READDIR request for larger than 1024 bytes of directory information. If this parameter is disabled, then the over-the-wire size is set to the lesser of either the size passed in by using the getdents system call or by using NFS_MAXDATA, which is 8192 bytes. For more information, see getdents(2).

When to Change

Examine the value of this parameter if an older NFS version 2 only server is used and interoperability problems occur when the server tries to read directories. Enabling this parameter might cause a slight decrease in performance for applications that read directories.
