[Xen-API] problem with vdi-resize XCP 1.0

[<simone.cariani@xxxxxxxxxx>]

Hi all,

 

i have a problem with vdi resize  from 40GB to 10GB in XCP 1.0.

 

XCP shows the following error:

 

[root@xcp1 ~]# xe vdi-resize uuid=c3fdc9ab-06d6-4f4c-aefc-42799ec800fc disk-size=10GiB

Error code: SR_BACKEND_FAILURE_79

Error parameters: , VDI Invalid size [opterr=shrinking not allowed],

 

 

 

The Smlog shows:

I have tried the resize with vdi that are stored in  both nfs SR and  Local Storage SR. But the problem persists..

 

Does anyone know a possible solution to resize the vdi?
