Description Sweta Anandpara 2016-02-12 10:18:44 UTC
Description of problem:
Had a 16 node setup, with a 6*2 volume 'testvol'. Ran FUSE I/O from clients and that went through. Did an attach tier 2*2, and it resulted in hanging of IO from fuse mounts. 'ls' on the mountpoint hanged as well. Rafi had a look at the setup. Disabled nfs on the volume, and I was able to regain the access of the mountpoints. 

Please note I had no NFS I/O running, or any of the NFS mounts active. 

Hit this while running the automated script 'attach_tier_trigger_rebalance' in tiering suite. 

Version-Release number of selected component (if applicable):
3.7.5-19

How reproducible: Hit it once
