Hi,

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


Did you have sharding enabled but not have any sharded VM images or were their shards missing on some bricks?  


Yes, interested to know why you had to turn off sharding. Could you elaborate?

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
