[one-users] [Datastores] Image Datastore has no size

Thu Apr 24 01:29:19 PDT 2014

Hi Eloi

It seems that the guide assumes a new feature of the 4.6 version, not
present in the 4.4 release. If you take a look the actual BASE_PATH is
/var/lib/one/datastores/1 (and not the one in the template). This path is
not available in the ESX hosts. So simply, create two new datastores. One
IMAGE_DS and the other SYSTEM_DS. You may use the template values shown in
the screenshot you send. Sorry for the error in the guide.

In this case for SYSTEM_DS is using the value in oned.conf (/vmfs/volumes)
so you get the right values

When you create the datastores, no directory will be created in
/var/lib/one/datastores. Note that for VMFS datastores they live in the
ESXs storage.

Yes the share the same storage medium so the potential available capacity
is the same for the two.
