copying files to shared folder via nfs create 0KB files

[andreaci]

QNAP TS-432XU firmware 4.4.2.1262 or TS-432XU firm 4.4.1.1216
it's impossible to copy file on qnap via nfs : the procedures create same files with 0KB dimension.
No problem same procedures, same files, same clients to shared folder via nfs on others QNAP TS-231P
Please help, it's necessary for backups

Both same NFS settings?

[andreaci]

Yes, same NFS settings.
But the problem is not for the clients. The clients can access to shared folder. Copying creates only empty file on qnap.

[storageman]

Just copy something to Public folder, same?

[andreaci]

same also in "Public" folder

[storageman]

Typically that's a permission issue.

I add this information
trying to copy a file from source folder (client linux) to destination folder (qnap)
so copying file "sourcefold/myfile.txt" from client to qnap share folder "destinationfold".
As result, on the qnap I have a file "destinationfold/myfile.txt" empty (0 KB) and on the client i have the error Cannot complete the operation because the file or folder sourcefold/myfile.txt already exists.

How much trouble would it give you resetting the config on that box?

No troubles because the nas is not in production but i don't know how to reset. Why would you do this? i passed from original firmware to latest firmware without any solution. What should be better ?

[storageman]

Some setting got screwed seems like.
Go for 3 second reset, or go through Control Panel. Reset settings

If this doesn't fix it would ticket time.

Finally i found the solution. even if it is not very elegant.
I downgraded the nas to the same firmware that i have in the oldest. From 4.4.1 (4.4.2) to 4.3.6
All works like a charm.

I'm waiting for support's answer.

Odd, 4.3.6.1070 build 20190919 says: "Users could not access mounted shared folders via NFS."

So having fixed it in 4.3.6 did they mess it up again!

Perhaps it's linux problem. I found over the net two other posts with same situation
