Storage replication

[fedele]

Hello,

I'm new to Proxmox and I'd like migrate my 3-node oVirt cluster.

My dubt is if in PVE there is a similar to ovirt gluster replica 3 storage

I can use filesystems, not devices, for replica

Can anyone have suggestions for me?

N.B. Can Ceph work on filesystem instead devices? Is it available a replica mechanism for vm disks?

You can create, configure, manage and use Gluster on your own, thus presenting GulsterFS to PVE as directory.
Its not natively built into PVE.

not directly, you may be able to create loop devices and force them into config, but you are on your own with that Frankenstein monster.

Is there a way to realize a replica of the vm disks on each hypervisor?

Thats a very broad question. Without any additional requirements/details, the answer is - it depends.

If I were to attribute some additional details to your question, then the answer _may be_ "yes" - by using ZFS replication available in PVE.

My idea is create a cluster of at least 2 hypervisors in HA and use the disks of hypervisor as storage

you may be ok with ZFS replication https://pve.proxmox.com/wiki/Storage_Replication

good luck

you have right i need at least three nodes, i suppose i can create my vm infrastructure on one node and then install the other two nodes to obtain HA
