Description of problem:
When doing a chmod -R on an NFS mounted volume, I get an Input / Ouput error on each file processed. After speaking on IRC about it, it seems we are two encountering that bug at least, on Debian 8 with the same version.
No problem on previous versions though.

Version-Release number of selected component (if applicable):
glusterfs 3.7.8 built on Feb 11 2016 05:58:55

How reproducible:
?

Steps to Reproduce:
1. Install Debian 8
2. Install the latest glusterFS from gluster repos
3. Create a volume
4. Mount it with NFS
5. chmod -R some files on it

Actual results:
Input / Output error on each file

Expected results:
No errors

Additional info:
Doesn't seem to happen with the same setup but older versions of glusterfs.
We spoke about it on IRC with jiffin on 15/03/2016 around 2 pm UTC, who asked for us to file a bug.

Having exactly same beavior on Debian 8 with lastest GlusterFS.

nfs.log showing me: [2016-03-15 14:07:43.776687] W [MSGID: 112199] [nfs3-helpers.c:3418:nfs3_log_common_res] 0-nfs-nfsv3: <gfid:a6ee3547-fd39-40ca-b381-041be04bc732>/StaticRecordCollection.php => (XID: d6165f74, SETATTR: NFS: 5(I/O error), POSIX: 5(Input/output error))
on all files that produce Output "Input / Output error on each file" while doing chmod -R or chown -R

If i recursively change file permissions on directories with just a few files the error doesn't occur. So it seems to be an issue with the mass of files that passing a permission change same time.

Please provide nfs logs and brick logs. Also it will be helpful if you could collect packet trace  (while the test is being executed) on the node where gluster-nfs server is running using below command -

 tcpdump -i any -s 0 -w /var/tmp/nfs-hang.pcap tcp and not port 22

If possible, please collect the packet trace in the older version servers as well.

glusterfs-server version 3.7.10-1 seems to have fixed this issue but brought a new one.

All my Glusterfs setups seem to loose their Quorum without any notice in log files at irregular days. 
I only can identify this after all client mounts went to "readonly filesystem" state and following log lines appear in nfs.log:

[2016-04-13 06:19:12.797704] W [MSGID: 112199] [nfs3-helpers.c:3418:nfs3_log_common_res] 0-nfs-nfsv3: /www/CENSORED/shared/usersettings/1/settings.conf => (XID: 3e2a6261, SETATTR: NFS: 30(Read-only file system), POSIX: 30(Read-only file system)) [Invalid argument]

for me it looks like it was an attempt to fix the previous reported bug and brought another one.
