Hi,

I need to configure simple 1.x style cluster beetween 2 servers on Proxmox 3.1.
I don't need HA, I don't have shared volume. I have only 2 servers with local storage area (HDDs in RAID).
I only need to have central aministration and offline migration possibility. Is it possible with Proxmox 3.1 ?
Any link for documentation ?

Regards,
Michu
 
Hi !

HA is not mandatory, If you don't have shared volume you can manage server 1 and 2 like a cluster with not shared datastore (simply server 1 has datastore 1 and server 2 has datastore 2).
The problem ... there is'nt a shared area... if you have an NFS volume shared.. you can try storage migration or use an NFS shared datastore for backup VM on server 1 and restore (offline) on server 2, but storage live migration is more simple.

If you don't wont a shared area, can try to backup VM on server 1 to localhost datastore, move backup via sftp (scp) to server 2 and restore... but a minimal share datastore for backup is recommended.

Hi,

Sorry for late response. Guys I need to have offline migration functionality like in Proxmox 1.x. I know that Proxmox 2.x and 3.x are basing on corosync while 1.x was basing on ssh and own algorithms.
I have a storage for backup (SSHFS) and I know that I can backup/restore machine.

This is not enough, I just ask if I can click "Offline migration" like in Proxmox 1.x and have machine stopped, compressed, send via network, decompressed, started. Is it possible in 2.x/3.x ? I know that this cause a downtime, but it's not a problem for me in my situation.
