Hi, 

I found the cause of this problem. I had to turn off sharding.

Hi, 

I updated glusterfs: 
glusterfs-client-xlators-3.8.12-1.el7.x86_64 
glusterfs-cli-3.8.12-1.el7.x86_64 
glusterfs-api-3.8.12-1.el7.x86_64 
glusterfs-fuse-3.8.12-1.el7.x86_64 
glusterfs-server-3.8.12-1.el7.x86_64 
glusterfs-libs-3.8.12-1.el7.x86_64 
glusterfs-3.8.12-1.el7.x86_64 

Now I cannot add a volume disk preallocated, after a while it breaks.

The glusterfs logs contain below errors:

Krutika, could you take a look?

Hi, 

I setup an ovirt hosted enine, in only one server with local gluster bricks. 

When running a MS SQL 2012 process to rebuild a data base, which take around 4 hours, after a while the VM is paused with the error: 
vm has been paused due to unknown storage 

The VM disk is in Thin provision

Ovirt and gluter versions:

Version 4.1.1.8-1.el7.centos

glusterfs-cli-3.8.11-1.el7.x86_64
glusterfs-libs-3.8.11-1.el7.x86_64
glusterfs-3.8.11-1.el7.x86_64
glusterfs-client-xlators-3.8.11-1.el7.x86_64
glusterfs-fuse-3.8.11-1.el7.x86_64
glusterfs-api-3.8.11-1.el7.x86_64
glusterfs-server-3.8.11-1.el7.x86_64 

I can find the reason why 
The logs are attached. 

Any idea? 

Thanks
