Curious question: How did the hardware corrupt the HE?

Dear All,

So we've had some major disk corruption on our hosted engine (hardware to blame), and we have taken backups. However, the hosted-engine VM will no longer boot at all, database is thoroughly corrupted, and we need to rebuild the thing. Just a sanity check on the best route:

Preamble:

VMs are still running fine - only hosted engine affected

VMs are distributed across our entire 3 node cluster

All 3 nodes are registered as hosted engine candidates

1. Do another hosted-engine --deploy on one of the existing hosts, and then restore the backup into that

2. Build a new host, deploy the hosted-engine, then restore a backup on a fresh node

Regards,

Callum
