Subject [URGENT] Mounting issues from KVM hosts to secondary storage
Date Thu, 03 Oct 2013 15:53:29 GMT
Dear all,

We face a major problem after upgrading to 4.2.0. Mounting from KVM hosts
to secondary storage seems to fail, every time a new VM instance is
created, it will use up the / (root) partition of the KVM hosts instead.

Here is the df result:

The strange thing is that df shows that it seems to be mounted, but it's
actually not mounted. If you noticed, the total capacity of the mount point
is exactly the same as the capacity of the / (root) partition. By right it
should show 7 TB instead of just 4 GB.

This caused VM creation to be error due to out of disk space. This also
affect the KVM operations since the / (root) partition becomes full, and we
can only release the space after we reboot the KVM host.

Anyone experience this problem before? We are at loss on how to resolve the
problem.

Looking forward to your reply, thank you.

Cheers.
