NFS Remote encryption problem
-
I am now also seeing the "Trying to add data in unsupported state" problem,
see this thread: https://xcp-ng.org/forum/post/84594
That did never occur when the remote used for this backup was not encrypted.

Hi,
Can you see if the specified path and file exist?
-
@stephane-m-dev the path exists but it was empty.

The problem doesn't happen on our enterprise NFS server with encryption.
But I tested on a freshly installed personal NFS server, and I get the same error as you if I use encryption.
We are investigating and will keep you informed.
-
It seems the problem happens when the directory shared contains non-hidden files.
Can you try to add a NFS remote with encryption on an new empty directory, and let us know if it works?This is not specified, but the encrypted remote must not contain encrypted and unencrypted file, as they may conflict.
We should add this information. -
@stephane-m-dev the folder was positively empty, I explicitly removed all files before adding it as remote. Have you read what I wrote about different share types in unRAID?
-
@djingo Do you have any error logs on the unraid server side?
-
@stephane-m-dev i checked, there was nothing
-
@djingo Can you share your NFS config file (/etc/exports) ?
-
the disk share (there the error occurs):
"/mnt/disk3" -fsid=87,async,no_subtree_check 192.168.100.0/24(sec=sys,rw,no_root_squash,insecure) *(sec=sys,ro,insecure,anongid=100,anonuid=99,all_squash)the user share (here it works):
"/mnt/user/backup" -fsid=91,async,no_subtree_check 192.168.100.0/24(sec=sys,rw,no_root_squash,insecure) *(sec=sys,ro,insecure,anongid=100,anonuid=99,all_squash)please also do not overlook the other problem with the full backup mode when encryption is used: "Trying to add data in unsupported state" (see above)

Thank you.
By reusing the same NFS config that fails on your server, I unfortunately could not reproduce the problem.
The only case where I saw the same error was when the shared directory already contained files, but you told me that was not your case.We will work on improving error handling to better identify NFS server-specific problems.
-
Maybe some hidden files? (eg be sure to display all files even hidden ones)
-
@olivierlambert No, in the code we only check for non-hidden files, and @djingo checked that the directory was totally empty.
-
@olivierlambert ls -halF - nothing was there
-
@stephane-m-dev well, have you tried this on an unraid server with a disk share? if not, you are still missing my point.
-
@djingo As said before, we will work on improving error handling to better identify specific issues with some users' NFS servers.
Unfortunately, we cannot reproduce the exact configuration of each user.
-
@stephane-m-dev understood. My suggestion regarding the different behavior (does not work with disk share, does work with user share) on unraid would be to put this in a "tip" in the documentation section about setting up Remotes.
