Subject Re: SSVM, templates and managed storage (iscsi/KVM)... how does it work ?
Date Sun, 03 Mar 2019 19:09:54 GMT
Hi Ivan,

SS is still on NFS in this case.  It's the primary storage in trying to
move on iscsi managed storage so just like Solidfire/Ceph on primary.

While NFS is used on both SS and primary,  I understand the SSVM just
mounts both shares and copies templates when needed.

But if you have a qcow2 template on SS,  and primary on managed storage,  I
presume the SSVM copies the qcow2 into the just dynamically created iscsi
volume in a raw way....  but I don't know that is what Im trying to connect
the dots :)
