NFSTEST_DELEGATION(1) nfstest_delegation 1.0.1 NFSTEST_DELEGATION(1)
NAME
nfstest_delegation - Delegation tests
SYNOPSIS
nfstest_delegation --server <server> [--client <client>] [options]
DESCRIPTION
Basic delegation tests verify that a correct delegation is granted when opening a file for reading or writing. Also, another OPEN should
not be sent for the same file when the client is holding a delegation. Verify that the stateid of all I/O operations should be the delega-
tion stateid. Reads from a different process on the same file should not cause the client to send additional READ packets when the client
is holding a read delegation. Furthermore, a LOCK packet should not be sent to the server when the client is holding a delegation.
Recall delegation tests verify the delegation is recalled when a conflicting operation is sent to the server from a different client. Con-
flicting operations are reading, writing and changing the permissions on the same file. Note, that reading a file from a different client
can only recall a read delegation. Also, verify that a delegation is not recalled when a different client is granted a read delegation.
After a delegation is recalled, the client should send an OPEN with CLAIM_DELEGATE_CUR before returning the delegation and the stateid
should be the same as the original OPEN stateid. Also, a delegation should not be granted when re-opening the file right before returning
the delegation. Verify client flushes all written data before returning the WRITE delegation. The LOCK should be sent as well right before
returning a delegation which has been recalled. A delegation should not be granted on the second client who cause the delegation recall on
the first client.

EXAMPLES
The only required option is --server but only the basic delegation tests will be run. Use the --client option to run the recall tests as
well
$ nfstest_delegation --server 192.168.0.11 --client 192.168.0.20
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.
