Hi,<div><br></div><div>What I meant it that an external script could monitor each physical host, get the free storage and, if it is lower that a threshold (e.g. 10 or 20 GB) execute a 'onehost disable hostname'.</div>
<div><br></div><div>This way you will prevent the scheduler from sending VMs to that host from that moment onwards.</div><div><br></div><div>Regards</div><div>--<br>Carlos Martín, MSc<br>Project Engineer<br>OpenNebula - The Open-source Solution for Data Center Virtualization<div>

<div>Hi,
<div><br></div>
<div>You are right, the OpenNebula scheduler does not check the available
storage.</div>
<div>But the scheduler ignores disables hosts, so you can set up a cron job to
gather the storage left in each host and execute 'onehost disable' or
'enable'.</div>
<div><br></div>
<div>Regards.</div>

<div>Hi,</div>
<div>I created a vm on opennebula2.2,but failed .Then i checked the vm.log,
and i found the reason:</div>
<div style="TEXT-INDENT:2em">scp: /one_images/277/images/disk.0: No space left on device
</div>
<div>So,i want to know before opennebula scheduling host ,will it check
the disk space whether meet the virtual machine .</div>
<div>In my opinion , if the host space is not enough to assign , it shouldnot
be scheduled.</div>
<div>Please masters pointing me .</div>
