RE: How to find the the vm's volume file in primary storage?

[David Ortiz <dp...@outlook.com>]

I am not sure how the generation occurs, but they are stored in the volumes table.  The id column relates to the uuid in the gui, and the path column is what the file name is I believe.
Thanks,     David Ortiz

Re: How to find the the vm's volume file in primary storage?

[David Comerford <da...@gmail.com>]

1. Rock over to the GUI, click on the instance your interested in

2. Get the ID of the volume from the Volumes tab. For example
4bedcf64-5526-4777-bac1-98c638c32116

3. Jump into MySQL client and run this query:
mysql> select folder,path from cloud.volumes WHERE
uuid='4bedcf64-5526-4777-bac1-98c638c32116' \G
*************************** 1. row ***************************
folder: /mnt/volgroup/primary1/export
  path: 12485e60-5700-4783-a8b5-b34a03e4bc3b
1 row in set (0.00 sec)
4. So the path to your volume's file will be folder+path.vhd, which in my
case here will be:
/mnt/volgroup/primary1/export/12485e60-5700-4783-a8b5-b34a03e4bc3b.vhd

Just to prove it:
# du -h
/mnt/volgroup/primary1/export/12485e60-5700-4783-a8b5-b34a03e4bc3b.vhd
267M
/mnt/volgroup/primary1/export/12485e60-5700-4783-a8b5-b34a03e4bc3b.vhd
CloudMonkley> destroy virtualmachine id=ee781871-ba63-41e0-835a-cde5edfefcfb

*twiddle thumbs waiting for expunge*

# du -h
/mnt/volgroup/primary1/export/12485e60-5700-4783-a8b5-b34a03e4bc3b.vhd
du: cannot access
`/mnt/volgroup/primary1/export/12485e60-5700-4783-a8b5-b34a03e4bc3b.vhd':
No such file or directory
Disk is gone. The theory is sound.
Hope this helps.
