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 delegation 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. Conflicting operations are reading, writing, removing, renaming and changing the permissions on the same file. Note that reading a file from a different client can only recall a write delegation. Removing the delegated file from a different client recalls the delegation and the server may or may not allow any more writes from the client after the delegation has been returned. Renaming either the delegated file (as source) or into the delegated file (as target) recalls the delegation. In the case where the delegated file is the target of rename, the existing target is removed before the rename occurs, therefore the server may or may not allow nay more writes from the client after the delegation has been removed just like in the case when removing the delegated file.
Also, verify that a read delegation is not recalled when a different client is granted a read delegation. After a delegation is recalled, the client may send an OPEN with CLAIM_DELEGATE_CUR before returning the delegation specially when there is a open pending on the client. In addition, the stateid returned by the new open should be the same as the original OPEN stateid. Also, a delegation should not be granted when re-opening the file before returning the delegation. The client may flush all written data before returning the WRITE delegation. The LOCK should be sent as well before returning a delegation which has been recalled. Finally, a delegation should not be granted on the second client who cause the delegation recall on the first client.

EXAMPLES¶
Run the basic delegation tests (no client option):
nfstest_delegation --server 192.168.0.2 --export /exports
Use short options instead:
nfstest_delegation -s 192.168.0.2 -e /exports
Run both the basic and recall tests using positional arguments
with nfsversion=3 for the second client:
nfstest_delegation -s 192.168.0.2 -e /exports --client 192.168.0.10:::3
Use named arguments instead:
nfstest_delegation -s 192.168.0.2 -e /exports --client
192.168.0.10:nfsversion=3
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.
