Ls command takes a long time to list shared files in two windows on a Windows-based NFS server

View products that this article applies to.

Symptoms

Consider the following scenario:

  • You have a computer that is running Windows Server 2008 R2 Service Pack 1 (SP1) or Windows Server 2008 Service Pack 2 (SP2).
  • The computer works as a Network File System (NFS) server.
  • You create and share files on the NFS server.
  • You use a mount command on a NFS client to connect to the NFS server.
  • You open more than one terminal window on the NFS client.
  • You run the following ls command in each terminal window at the same time to list all shared files:
    cd <NFS share>
    ls –lR
In this scenario, it takes longer than expected to list all the shared files from the NFS server.

Cause

This issue occurs when the NFS client sends a GETATTR call two times in a row. The NFS server has to wait for the ACK packet from the NFS client for the first GETATTR reply packet before it can send the queued second GETATTR reply packet.

Note In most cases, it takes about 0.04 sec to send the second GETATTR reply packet because of delayed ACKs from the NFS client. Therefore, when you execute an ls command, it takes more than two hours to list all files for the attribute information when the total number of files is more than 400,000.
(400,000 * 0.04 sec / 2 Nfs3GetAttr() calls / 3600 sec = 2.22 hours)

You can confirm how long it takes to send the GETATRR reply to the NFS client by monitoring network packets.

Resolution

To resolve this issue, install hotfix 2957486 on the NFS server.

Note Even though this issue has only been observed in Windows Server 2008 R2 or Windows Server 2008, the hotfix also applies to Windows 7 or Windows Vista.

Windows 7 and Windows Server 2008 R2 file information and notes
Important Windows 7 hotfixes and Windows Server 2008 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 7/Windows Server 2008 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
  • The files that apply to a specific product, milestone (RTM,SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    VersionProductMilestoneService branch
    6.1.760 1.18xxxWindows 7 and Windows Server 2008 R2SP1GDR
    6.1.760 1.22xxxWindows 7 and Windows Server 2008 R2SP1LDR
  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
