hard linked home dir????

I have recently discovered an unusual and unexplainable thing on my readynas and I am hoping someone has some insight about it. Something has created a hard link to my home dir, calling it the same as my email address... but the weird thing is, it has the same inode number, but if I cd into it, it does not show the same contents, its empty... I am unable to delete it. All attempts to remove it give me the error "Operation note permitted".

Does anyone ahve any idea what this seemingly hard linked file is? its the same inode as my home dir, but like I said, if I cd into it, it doesn't have the same contents. And I can't delete it. I also see that something or someone added my email address to /etc/passwd, and references this dir.

I did not create this. It is dated July 23, which is right around the time I updated to 6.8.0, so the question is, is this something related to Readynas OS6, perhaps one of the cloud services or something? I really don't have anything unusual installed on this machine that should have done something like that and the fact that this folder appears to be some kind of very low level link makes me think Netgear put it there. Does anyone know?

yep, readycloud is the one! I had to hit the "leave" button the readycloud screen in frontview and that nuked the folder. Need to learn a little more about how readycloud works...but thanks for that.

I suspect it's a ReadyCloud account. Did you look in the web ui on the cloud users page?

Where exactly are you seeing the hard link?

  well I don't actually know for sure its a hard link...as there is no way to see if something is a hard link or not. What I can see is that all the dirs under /home have the same inode value...but that might be normal for dirs, I'm not sure.
  
  But what I can say is that this dir with the same name as my email, is there, I can't remove it and I'm not sure how it got there or why I can't remove it.

    /home is a mount, it should be showing you the same information as /data/home. Normally a folder there means that username of <email> was created by the system (and that someone logged into that account). ReadyCloud of course uses that convention, so you should look on the "cloud users" tab of the accounts page in the admin web ui.
    
    Subvolumes all show an inode of 256 (and I believe each users's home folder is a btrfs subvolume).
