Description nchilaka 2018-04-13 12:21:51 UTC
Description of problem:
I had lot of files on my ec volume on 3.12.2-6 build. 
I did an offline server upgrade to 3.12.2-7 . Also upgraded the clients to the same build(did a fresh mount post upgrade)
I then tried to delete the old files, and when we access the files I am seeing below messages logged for every entry in fuse mount log
