Hi!

I'm running a cluster with PVE 1.8 on 4 physical servers.
On 3 Machines are running virtual machines, 1 is hot-spare.
There are two different Storages attached:
  1. a Fibrechannel-Raid as backing for LVM (fast)
  2. a ISCI-Storage as backing for LVM (cheap)

Now I want migrate this Cluster to Version 2.0.
I plan to remove the hot-spare from the 1.8-cluster,
install 2.0 on it an take the machines one by one over to the 2.0.
When the next physical server is 'empty' I remove it from the 1.8 cluster,
install 2.0 and so on and so on ....

One problem with this solution is, i must backup & restore each
attached LVM-Volume-Storage. This means I need additional storage
for the migration and it costs a lot of time.

Is there a way to keep the data on the LVM and just migrate or convert the
configuration for 2.0?

Is it possible to attach the storage to both cluster (1.8/2.0) and both see the same LVs?

Is there a tutorial or 'best practice' to do somthing like that?

:confused: Maybe my plan is wrong, has anybody a better idea?

Thanks,

Kurt Stieger

hi tom.

thank you for the reply but I'm afraid this is not the answer for my questions.
I read the wiki-article previously but it gives no answer to my questions.

Can I go the direct way from 1.8 to 2.0?
Is there a way to use the contents of the 'LVM-Images' again, just rewrite the config?
Is it possible to use the same storage while migration on the 1.8 Installation and on the 2.0 Installation?

sincerely yours, kurt
