Subject inventory storage volumes on primary storage
Date Wed, 01 Apr 2015 00:28:23 GMT
HI, all:

I am doing an inventory of all vhd files on my primary storage device.   I have only eight
active VM instances, but I have 43 vhd files on file system.  Running cmd “xe vdi-list”
on XenServer provides infor on all vhd files.  From the output,  I can tell that “name-label”
field generally matches the disk names shown in CS web UI for active volumes, or for templates
copied over to primary storage.  However,  there are a number of vdi’s whose “name-label”
field is either blank or “base copy”, as shown below:

# xe vdi-list

           read-only ( RO): false



(more output)


My questions are: 1) what are those VDI’s whose “name-label” is blank, can I safely
delete them from file system ? And 2) what are those “base copy” VDI’s, how do I find
out which VM / templates they belong to ?


Thanks,


Yiping
