Hi and thanks for reply! Thanks for idea, but take a look to my setup step by step, maybe I miss something?
1. Hardware Node1 - supermicro server with good cpu and 256Gb RAM, 3 15k SAS, 5 SSD's. Node2 - absolutely same server like Node1 Node3 - small little PC with 4Gb RAM and one 500Gb SATA disk Network 1Gbps via VLAN (nodes are not in the same place) What I need: Virtual Machine in H/A mode (if some of two nodes die, vm should be started up on the second node) 2. My configuration steps on Node1 and Node2: - In first of all of course is clear installation of Proxmox 5.2-1 to every node - In disk section of installer I prepare ZFS setup with 3 SAS 15k disks in ZFS-RAID1 mode - Network for nodes is placed in private subnet 172.31.101.0/24 - After install process I will configure addition file storage with 5 SSDs in ZFS-RAIDz3 mode 3. My config steps on Node3: - Simple install proxmox 5.2-1 on 500Gb SATA disk with ext4 and default LVM setup - Network for node is placed in private subnet 172.31.101.0/24 too 4. Configuring proxmox: - I logged via web to Node2 and configure Cluster (in web - Datacenter => Cluster => Create cluster) - Then I will login to Node1 and click "Join Cluster", then I'll copy here join info and cluster ready - After that I will configure local storage parameters, and check SSDs storage for use only with this two nodes - Now its time to add Node3. Paste join information and cluster is online with 3 nodes and quorum. 5. Virtual machine. - VM is created and placed on node2 - Same physically network is used (but another IP subnet) - Setting up replication for this VM to node1 (every minute */1) - Setting up H/A for this machine and request "started" state - Then I'll create Group in H/A where I will check only node1 and node2, also I will check "restricted" checkbox Setup is works fine. If some node dies, VM will be started after fencing will completes. But this setup will die after one-two days. After that, Cluster is looks like not defined, but nodes are still avaliable for each other on the network. VM does not works, all work is stalled. I read in manuals something about MASTER node... May be I must register node3 as master? But if I do that, I won't get SSD's storage, what is presend on node1 and node2, but not on node3.
