Effectively, it's very surprising. I checked my differents storage (local as iscsi sr) on xcp 1.0, xcp 1.1, xcp 1.4.90, xcp 1.6, xenserver 6.0 and xenserver 6.2, i observe that i can have a 'used' storage more important that the 'allocated' one
I verified connected to my hypervisors shells and verified the data displayed in xencenter, the value 'used' is the good one. However, i can have allocated 200GB on my local SR to one vm (so it's provisionning). I can have 33GB 'used' on my local SR, but i have in reality less storage available into my vm. More clearly, if 200GB allocated on one vm, if xencenter says me 33GB are used, i can retrieve a vhd file corresponding to my vm of a size of 33GB, but when i'm connected to the vm's shell, i don't retrieve my 33gbs of storage. I observe the same phenomenon with my others xenserver hypervisors. It seems that some metadatas could be present into the vhd file + the real vm storage. Is there any citrix xenserver specialist in the room to confirm (or not) what i said ? Thanks. Regards, Benoit. 2013/10/4 Mike Tutkowski <mike.tutkow...@solidfire.com> > Doh!
