            Bug ID: 1291635
           Summary: tier : Demotion failure for char type file
           Product: GlusterFS
           Version: mainline
         Component: tiering
          Severity: medium
          Priority: medium
          Assignee: bugs at gluster.org
          Reporter: jthottan at redhat.com
        QA Contact: bugs at gluster.org
                CC: bugs at gluster.org



Description of problem:
Demotion failure for char type file. It should fail all special(CHAR, BLOCK,
SOCKET etc) type files other than regular, but for me issue is seen in char
type file. From the logs, it is clear that lookup(dht_revalidate_cbk) on this
file failed in cold tier due to type mismatch 

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

How reproducible:
always

Steps to Reproduce:
1.Create and start a tier volume
2.set tier mod= test(preferable to use other demotion paremeters)
3.mount the volume(any protocol) 
4.create a char type file using mknod
5.after some time(promotion will happen)
6.When tier daemon tries to demote, it will fail. Failure messages are flooded
in tier log

Actual results:
Demotion failed

Expected results:
Demotion should not fail

Additional info:
snippet from tier daemon log :
