Bug 1020870

Description of problem:

The problem is I am getting "No volumes present" for gluster volume info command even though I am having a volume.


Presently I upgraded my system to glusterfs 3.4.0.35rhs from 3.4.0.34rhs.

Already I was having a volume, with quota enabled and over nfs mount the I/O was going on.
Before updating the rpms I have stopped the volume.

Now after updating the rpm using yum update.

I tried to check the status of the system and it did provide me status properly.
Even I/O over nfs resumed after I started the volume.

But executing some gluster related commands, gluster volume info fails to provide the information of single existing volume.

Before gluster volume info failure, setting the quota-deem-statfs comamnd also failed.

[root@quota2 ~]# gluster volume set dist-rep quota-deem-statfs on
volume set: failed: Another transaction is in progress. Please try again after sometime.

In actaul results section, mentioning the sequence of commands and there outputs.

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

Expected results:

Seems it went to some inconsistent state and could not collect the correct info.

Additional info:


Before executing all the commands mentioned in "Actual Results" section, 
I executed gluster volume quota $volname list and it listed me 2679 directories successfully.
