Node Storage Failure and Recovery

Afternoon all,
Running Start9 latest on a proxmox node with dedicated storage for start9.
The Drives had a failure, which shouldn’t happen but did.

I tried to restore from the old drive itself but encounter no end of RPC errors on read and abandoned that recovery path.

I eventually chose to restore from backup, which worked and the blockchain has been re-syncing for several days now. As I write this sitting at about 80%

I want to verify I understand what happens next.

Thunderhub and LND are both running, my node shows online in Amboss but all channels have closed. I think this is expected from what I’ve read but I didn’t fully understand that.

Node id:

My questions are:
Am I correct in assuming those channels are gone forever? There’s no way to re-initialize or restore?
If not, how does one restore, or properly close and recover funds?
Is there a guide on how to recover funds?

I’ll wait for the blockchain to fully sync before I “meddle” with anything but any ideas, instructions or insights would be greatly appreciated.
