Subject Re: new primary storage
Date Fri, 10 Jan 2020 11:10:51 GMT
Hi all,
I keep getting the following error about a volume that has been migrated:

volume:d93d3c0a-3859-4473-951d-9b5c5912c767

what could happen if I create a symbolic link between the file currently in
use (the actual path of volume in use) and what cloudstack is looking for
(the d93d3c0a-3859-4473-951d-9b5c5912c767, the uuid of volume in use) so
that it can collect the data of the file?
