Using the SVR5 ndcert test suites

NFS STRESS test suite


Synopsis:
auto_nfs all

Configuration file:
nd-nfs.cfg

Test suite name:
nd-nfs

Summary:
Stress tests NFS by simulating a user application doing read and write operations to an NFS mounted file system. This tests the network over the UDP protocol at an application level by copying a large file across the network to a remote file system and back again, Then comparing the contents of the original and copied files. The file system is unmounted between the write and read operation to ensure that all data is flushed to the filesystem. The test passes if it completes a fixed number of iterations (default 500) without any loss of data or loss of access to the NFS server.

Prerequisites
A filesystem must be set up on both the master and slave machines that can be mounted as an NFS filesystem on the other machine. These filesystems must be writable. By default, /mnt is used; to make the filesystem shared, use the following command:
   share /mnt

Media types:
All that support NFS.

Init state:
3

Executing machine(s)
master only

Execution time:
Depends upon the ITERATIONS configuration variable; each iteration takes about 3 seconds. Execution time varies considerably depending on the network traffic, speed of the machine, speed of the media, filesystem architecture used, and so forth.

Number of test cases:
1

Number of invokable scenarios:
1

Configuration variables:
The parameters for this test are set only on the master machine since the test is not run on the slave machine.

REMOTE_MACHINE
Enter the full domain name of the slave machine being used for testing.

REMOTE_FS
Mount point of the filesystem on the slave machine that is shared and can be mounted remotely on the master machine as an NFS filesystem. Default value is /tmp.

LOCAL_FS
Mount point of the filesystem on the master machine that is shared and can be mounted remotely on the slave machine as an NFS filesystem. Default value is /tmp.

ITERATIONS
Number of times the test should be executed. Default is 500.
