linux client - shell hangs when operating in the root of a share with snapshots=allow snapshot acces

I am testing an RN204 using OS 6.4.2. 

 

I have a share that has snapshots enabled. I have set "allow snapshot access" on the share. The share is mounted using nfs on a linux client. If I do anything in the root of the share from the linux client, the shell hangs. For example:

 

share = TestSnap

from a shell (terminal) on the linux client

 

cd TestSnap

ls -al =hangs the shell!

 

Many other operations in the root will hang the shell also. Such operations include cp, mv etc. 

 

If I operate in a subdirectory of the share there is no problem:

 

cd TestSnap/TestDir

ls -al =works

 

I have confirmed that the presence of the snapshots and "allow snapshot access" is the culprit here. If there are no snapshots, or if snapshots are hidden, this problem does not exist. This problem occurs using either nfs3 or nfs4.

 

Just thought I would document this issue in case others run into it.

    Hi TullyNYGuy,

     

    Does this happen you will access it via SMB or Windows File Explorer?

     

    I may also need to replicate and check this with my colleagues. I will get back to you as soon as possible.

     

     

    Kind regards,

    Hi TullyNYGuy,

     

    I reproduced the issue on my machine on F/W 6.5.0 RC1.

     

    ## Created a share on the NAS
    ## Allowed NFS
    
    ## Mounted the share on a Linux machine
    # mount <ip>:/<volume>/<share> /mnt
    
    ## Listing the content of the mount point works ok and prompt is released
    # ls -alh /mnt
    [bla bla bla]
    #
    
    ## Took a snapshot (not sure if necessary)
    ## Allowed snapshot access on the share using the GUI
    
    # Listing the same mount point hangs and the prompt is NOT released
    # ls -alh /mnt
    [... hangs ...]


    So this is a BUG, and not corrected in 6.5.0
