I just found out this Site is still running ganesha-2.3.2. I assume there have been an enormous amount of changes here. Is there any way to figure out when this version was released?

If it’s V2.8.3 you might want to try V2.8.4, that includes readdir fixes.

 

So the issue is the directory never shows up in a directory listing, but you can navigate into it (LOOKUP)?

 

If you can run with the following debug config:

 

LOG {

    COMPONENTS {

        CACHE_INODE = FULL_DEBUG;

    }

}

 

And show us an attempt to list a directory with sub-directories, and then a successful cd into the directory, that might help.

 

Daniel, any other thoughts?

Thank you Frank,

 

Weka (my company) has had a few issues with the NFS 16 group limitation as well as file locking. We utilize an "Native" NFS solution which we are transitioning from to a Ganesha implementation actually in a later Weka version. For this customer they couldn't wait for that feature. In this case Wekafs is mounted on a customer host which in turn is presenting a stand-alone Ganesha instance. When logging on to the ganesha server file/dir operations have no issue and files/dirs are accessible and visible on the ganesha server where weka is mounted. I also believe this is ganesha version 2.8.3 as far as I know. I'm working on trying to recreate this in AWS. Frank, I think I emailed before and you responded to an earlier issue where we couldn't reproduce but the files eventually became available whereas this instance it seems they don't. While the reproduction is still underway are there any settings related to this type of situation?

What underlying filesystem?

 

We may need some debug logs and/or tcpdump traces to figure out what’s going wrong.

Thank you Daniel for your reply,

 

If you have 2 folders, one nested, /dir1/dir2 and you issue an ls command in dir1. It won't show dir2 however you can cd into that directory directly.

 

The ganesha config is as follows:

 

###################################################

NFSV4
{
DomainName = lmco.com;
}

NFS_CORE_PARAM
{
NFS_Port = 2049;
        MNT_Port = 20048;
        Rquota_Port = 875;
        NLM_Port = 32803;
        NFS_Protocols = 3,4;
}

EXPORT_DEFAULTS
{
Access_Type = RW;
Manage_Gids = true;
        Protocols = 3,4;
        Transports = TCP;

}

EXPORT
{
# Export Id (mandatory, each EXPORT must have a unique Export_Id)
Export_Id = 4;

# Exported path (mandatory)
Path = /scratch;

# Pseudo Path (required for NFS v4)
Pseudo = /scratch;

# Required for access (default is None)
# Could use CLIENT blocks instead

# Exporting FSAL
FSAL {
Name = VFS;
}
}

 

Thank you

David

I'm not sure I'm understanding the problem here.  Is it that you can
list a file but not see it's contents?  Or is it that you cannot list a
file, but can still open the file if you use a full path to it?  Is it
files, or directories, or both?

What version of Ganesha are you using?  What FSAL are you using?
