Description of problem:
======================
Volume mount is failing when volume option "cluster.extra-hash-regex"  is set to '(.*)\.swp*'


errors in the mount log when it failed:

Version-Release number of selected component (if applicable):
=============================================================
glusterfs-3.8.4-2

How reproducible:
==================
Always


Steps to Reproduce:
===================
1. Create a replica of any size and start it
2. Set the volume option "cluster.extra-hash-regex"  is set to '(.*)\.swp*'
3. Try to fuse mount the volume  // It will fail

Actual results:
===============
mount is failing when volume option "cluster.extra-hash-regex"  is set to '(.*)\.swp*'

Expected results:
=================
i don't the reason why mount should fail when this volume option is set.

Comment 3 Nithya Balachandran 2016-10-17 09:58:43 UTC

This is not a commonly used option. Moving this to 3.2.0-beyond.

Comment 4 Nithya Balachandran 2016-10-25 07:33:56 UTC

Note to self:

I was able to get the mount to succeed by editing the volinfo file to put quotes around the regex value.

Comment 7 Nithya Balachandran 2017-08-22 08:31:36 UTC

This is not really a dht BZ seeing that this seems to be an issue with volfile generation or the graph parsing when dealing with wildcards.

Moving this to Atin to process accordingly.
