Dear All,
Does anyone have experience in replacing secondary storage?
We need to replace current sec storage(with a new one) as it will soon be end
of support.
We are considering the process as follow.
1.) Register new secstore.
2.) Make new template to be created in new secstore.
3.) Make new snapshot to be created in new secstore.
4.) Copy current template and snapshot from old secstore to new secstore.
5.) Change db info of copied template and snapshot to reflect new secstore.
We know (1) very well :)
We would like to know if there is any way to achieve (2) and (3).
Regarding with (4),
There are 4 dir under SecStorage. (Snapshots, systemvm, template, volumes)
In our understanding, only snapshots and template dir are necessary to copy
to new storage.
Systemvm and volumes dir are not necessary to copy as it is for temporary
storage.(Original data are stored in primary store.)
Please correct me if I am wrong.
Regarding with (5),
For template, we assume it is enough to change template_store_ref.store_id to
new secstore.
Please correct me if I am wrong.
For snapshot, we would like to know what db info should be changed for
XenServer and VMware.
(XenServer implement 16 chains while VMware use full clone in taking
snapshot.)
Thanks,
