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.
