upgrading from 1.9

[coffe]

Seems like we are going to get a OK to upgade.
So i just like to get som input.

have today a cluster of 6 servers anv about 20VMs on all of them.
My ide where to use a old server to install 2.* and then copy the clients over. but i dont like to keep that server in cluster so is there a easy way of removing it as master of the new cluster ?

Any input would be good .


Cheers

Hi, in proxmox 2.1 there are no master nodes so should be a case of seting up your new cluster and then removing the node after joining the other nodes to the cluster.

So today we are going to install a new 2.* server to build the new cluster.
as we only use iscsi will we run in to big problems if we have it shared between a 1.9 cluster and a 2.* ?

Second question is whats the best way of moving a vm from the 1.9 cluster, seems litle strange to dump it and relad it as its on shared storage , seems like there have to be able to just add the servers vm config file ?

as we cant shut down all hosts , we are going to do this in steps, so first move one servers vm over to a new , then update that server to 2.* and add it to the cluster and so on.

got 2 new questions.
1.i have moved the .conf file to the new server, but it seems the system dont connect to image in shared storage. how can i "mount" it so it finds it ? ( /dev/mapper/ )
2. do i have to make the cluster before adding nodes ( its the first server in the cluster to be).

We activate the storage when you start a VM.

2. do i have to make the cluster before adding nodes ( its the first server in the cluster to be).

Hi,
Havent seen anything about creating cluster before adding VMs ,
If i try start it, it says it dont find HD image. but when checking the storage i can see it. but a ls /dev/mapper dont show it.

 

[coffe]

lvchange -ay /dev/volumegroupname/vm_id seems to worked.
No. VM stills says it cant find any boot on it, so i did test to start it up in old cluster, ans there it did work.

What is the output of

# pvesm list <STOREID>

please replace <STOREID> with the ID of the storage which does not work.

seems like the VM i where testing with where created with scsi , the others all use virtio, so it works. tomorrow will be grand day of moving 40+ VMs.
Tnx everyone
