[Xen-API] Local Storage Missing 200+ GB

[Asai <asai@xxxxxxxxxxxxxxxxxxxxx>]

Greetings,

Running XCP 1.6.  This seems to be a recurring problem with many people, running snapshots seems to be slowly eating up space. Where we have a 1 TB local storage capacity and 700 GB of VMs running, we're up to 99% capacity used on the local storage drive. Out of 9 VMs, there seem to be 6 that are hidden which I'm unable to view in XenCenter even by revealing hidden objects. Basically I need to know what the best technique is for cleaning up the space here.  I tried running the coalesce-leaf command but got an error:

[root@ultimata ~]# xe host-call-plugin host-uuid=7d56ad1f-34f2-4efb-9635-623aca23df39 plugin=coalesce-leaf fn=leaf-coalesce args:vm-uuid=fb7a4699-6e28-49ef-b4ca-6b6db122b458

There was a failure communicating with the plugin.

status: leaf-coalesce

stdout: KeyError

stderr: 'vm_uuid'

I hesitant to export and re-import the VMs because that can make for hours of downtime for critical servers.  Any insight is much appreciated.

 The output of vdi-list, vhd-util scan and lvscan is as follows:
