hi,
I run following test command and stuck at recall12 recall14 recall20
recall22 recall40 recall42 recall48 recall50.
./nfstest_delegation --nfsversion=4 -e /nfsroot --server <server ip>
--client <client2 ip> --trcdelay 10
./nfstest_delegation --nfsversion=4.1 -e /nfsroot --server <server ip>
--client <client2 ip> --trcdelay 10
./nfstest_delegation --nfsversion=4.2 -e /nfsroot --server <server ip>
--client <client2 ip> --trcdelay 10
recall12 recall14 recall20 recall22 recall40 recall42 recall48 recall50
tests write files after remove.
After comment out above testcases result is:
646 tests (588 passed, 58 failed)
FAIL: WRITE delegation should be granted
run ./nfstest_dio have following messages.
INFO: 16:19:51.455222 - WRITE delegations are not available -- skipping
tests expecting write delegations
test OS: RHEL9.2 Nightly Build
Why do these testcases can not stop?
best regards,

Are you asking why these testcases don't pass? If you're testing against
the kernel's NFS server then it's because it does not (yet) support
write delegations.

run following command and test result is attached.
./nfstest_delegation --nfsversion=4 -e /nfsroot --server 192.168.122.110
--client 192.168.122.109 --trcdelay 10 -v all --createlog --keeptraces

Hello,
First of all, the --client option can be used successfully when the system in which you are running the test is able to capture the traffic for both clients, e.g., when you are running VMware and both clients are VMs. If you are using real clients, tcpdump will only capture traffic for the local system.
./nfstest_delegation -h
Test options:
--runtest=RUNTEST
Comma separated list of tests to run, if list starts with a '^' then
all tests are run except the ones listed [default: 'all']
--client=CLIENT
Remote NFS client and options used for recall delegation tests.
Clients are separated by a ',' and each client definition is a list
of arguments separated by a ':' given in the following order if
positional arguments is used (see examples):
clientname:server:export:nfsversion:port:proto:sec:mtpoint [default:
'nfsversion=3:proto=tcp:port=2049']
--client-nfsvers=CLIENT_NFSVERS
Comma separated list of valid NFS versions to use in the --client
option. An NFS version from this list, which is different than that
given by --nfsversion, is selected and included in the --client
option [default: 4.0,4.1]
The second client is a combination of --client and --client-nfsvers and the default for --client is 'nfsversion=3:proto=tcp:port=2049'. This means that the mount for the second 'client' is on the main client with the following nfs mount options: 'nfsversion=4.0:proto=tcp:port=2049' or 'nfsversion=4.1:proto=tcp:port=2049' depending on the value for option --nfsversion. In you case, --nfsversion=4 (if you mean 4.0) the mount options for the second client should be 'nfsversion=4.1...'. This way main mount is 4.0 (holding delegation) and the second mount is 4.1 (recall delegation) on the same system so the network traffic could be fully captured.
Of course, if you specify --nfsversion=4, the client will mount either 4.2, 4.1 or 4.0 (in your logs: NFS version of mount point: 4.2). You need to explicitly specify the NFS version as 4.0, 4.1 or 4.2.
The reason why the test is hanging is because the server is sending NFS4ERR_DELAY to COMMIT:

As Jeff mentioned earlier, Linux server does not grant write delegations. I don't know what server are you using but the OPEN clearly shows it did not grant a write delegation so this test should fail.
Here is a sample run against a RHEL 8.6 server:

hi,
Thanks for reply.
> Of course, if you specify --nfsversion=4, the client will mount
either 4.2, 4.1 or 4.0 (in your logs: NFS version of mount point: 4.2).
You need to explicitly specify the NFS version as 4.0, 4.1 or 4.2.
I understand.

I run test OK in RHEL 8.6 server.
best regards,

> The second client is a combination of --client and --client-nfsvers and the default for --client is 'nfsversion=3:proto=tcp:port=2049'. This means that the mount for the second 'client' is on the main client with the following nfs mount options: 'nfsversion=4.0:proto=tcp:port=2049' or 'nfsversion=4.1:proto=tcp:port=2049' depending on the value for option --nfsversion. In you case, --nfsversion=4 (if you mean 4.0) the mount options for the second client should be 'nfsversion=4.1...'. This way main mount is 4.0 (holding delegation) and the second mount is 4.1 (recall delegation) on the same system so the network traffic could be fully captured.
