Migrate virtual machines and regular storage containers to a shared one like ceph in proxmox 6.1

[POL CRIOLLO]

My greetings.
I tell you that I have an environment in production 03 nodes, with virtual machines and containers running normally.
Now I need to put high availability into operation, but all the info I find recommends having shared storage, you can use ceph.
Some of you know the method to configure shared storage with ceph and migrate existing virtual machines and implement high availability.
I am using proxmox 6.1
Best regards.

You basically need to add some disks for ceph OSDs on all three servers (at least one each), then you can create a ceph setup through Proxmox VE. After that you can move the disks of the existing VMs to a ceph pool and you'd be done.

I understand all that, high availability and shared storage is not yet implemented.
But in this mount I want to know, how to recover the data of a node that had two disks with zfs raid0, but one disk failed and only one remains operational, what should I do to achieve it.

Your data is probably lost, RAID0 is, well, no redundancy at all. If you cannot somehow salvage the disks content then any data on it is gone. If you want redundancy use RAID1, or RAID10 with (e.g.) 4 disks. You can try to salvage some data with zdb but you would to be very very very lucky to get anything out of it.

Also, open new threads for new topics.
