Hi chjatwork, Are you mounted to the /ifs directory with an account that has the right privileges?  To be clear, I'm assuming you're mounting the share with smb.   Can you try mounting /ifs in nfs and traverse to the location in question?
Hey,  I am trying to do a diff against my robocopy of a Isilon CIFS share to a remote system, but to ensure I do it from a stabled F/S I wanted to run the diff against a snaphshot instead of the actual F/S which is being consistently written to.  I am using a MAC to run my diff command against the 2 shares.  The MAC is running 10.7.5.  I can navigate to the /ifs/.snapshot folder, but I can not get all the way down to see the contents of the folder I am trying to perform the diff on.  Its funny because on the Isilon I can navigate to any and everything within the snapshot.  Why can't I navigate anywhere and everywhere from my MAC?  Even on Windows it will let me navigate everywhere and anywhere within a snapshot.  I even tried running an ls -a, but it still did not work.  Please help.  Thank you,
/ifs/.snapshot
