[one-users] wrong restart -> delete disk image!

[samuel]

Hi folks,

Recently there was a network problem and one instance became unreachable. We
tried to restart it with stop and resume actions but there's been a problem
and the disk has been deleted. The main concern is why, after trying to
restart and an error happened, the directory where the disk image resides
has been deleted? There was no sensible data on it but I just don't get why
there has been a rm -rf of the directory.

Details:

The configuration is KVM with shared storage using open nebula 2.2.
