TESTS
acregmin_attr
Verify consistency of attribute caching by varying the acregmin NFS option.
The cached information is assumed to be valid for attrtimeo which starts at acregmin.
acregmax_attr
Verify consistency of attribute caching by varying the acregmax NFS option.
The cached information is assumed to be valid for attrtimeo which starts at acregmin. An attribute revalidation to the server that shows no
attribute change doubles attrtimeo up to acregmax. An attribute revalidation to the server that shows a change has occurred resets it to
acregmin.
acdirmin_attr
Verify consistency of attribute caching by varying the acdirmin NFS option.
The cached information is assumed to be valid for attrtimeo which starts at acdirmin. Test that this is so.
acdirmax_attr
Verify consistency of attribute caching by varying the acdirmax NFS option.
The cached information is assumed to be valid for attrtimeo which starts at acdirmin. An attribute revalidation to the server that shows no
attribute change doubles attrtimeo up to acdirmax. An attribute revalidation to the server that shows a change has occurred resets it to
acdirmin.
actimeo_attr
Verify consistency of attribute caching by varying the actimeo NFS option.
The cached information is assumed to be valid for attrtimeo which starts and ends at actimeo.
acregmin_data
Verify consistency of data caching by varying the acregmin NFS option.
acregmax_data
Verify consistency of data caching by varying the acregmax NFS option.
The cached information is assumed to be valid for attrtimeo which starts at acregmin. An attribute revalidation to the server that shows no
attribute change doubles attrtimeo up to acregmax. An attribute revalidation to the server that shows a change has occurred resets it to
acregmin.
acdirmin_data
Verify consistency of data caching by varying the acdirmin NFS option.
The cached information is assumed to be valid for attrtimeo which starts at acdirmin. Test that this is so.
acdirmax_data
Verify consistency of data caching by varying the acdirmax NFS option.
The cached information is assumed to be valid for attrtimeo which starts at acdirmin. An attribute revalidation to the server that shows no
attribute change doubles attrtimeo up to acdirmax. An attribute revalidation to the server that shows a change has occurred resets it to
acdirmin.
actimeo_data
Verify consistency of data caching by varying the actimeo NFS option.
The cached information is assumed to be valid for attrtimeo which starts and ends at actimeo.
EXAMPLES
Required options are --server and --client
$ nfstest_cache --server 192.168.0.11 --client 192.168.0.20
Testing with different values of --acmin and --acmax (this takes a long time)
$ nfstest_cache --server 192.168.0.11 --client 192.168.0.20 --acmin 10,20 --acmax 20,30,60,80
NOTES
The user id in the local host and the host specified by --client must have access to run commands as root using the 'sudo' command without
the need for a password.
The user id must be able to 'ssh' to remote host without the need for a password.
