It lost about 5% of saltlake IIRC (I may be wrong, but the drives lost were 4TB each and most of the data on those where backups)
Hello @gengis ,
Welcome to the forum!
The disqualification is permanent and not reversible, especially if there were a data loss.
If your node is not DQ on all satellites, you can continue to run it (but likely it would be DQ on other satellites as well).
If it’s DQ on all satellites, then you need to remove this identity and its data, generate a new one identity, sign it with a new authorization token and start with a clean storage.
Or like suggested by @arrogantrabbit - you may run a new node in parallel (but point it to a different pool), it would take all the traffic from the customers of the satellite, which has been disqualified your first node, and would share the traffic from the customers of other satellites with your first node.
Regarding destroyed RAID - this is why we do not suggest to use RAID any kind, unless you already have it and it has been used for your stuff. If you were run a separate node with own unique identity for each HDD, you could lost only small amount of the common data (because all nodes in the same /24 subnet of public IPs are treated as a one big node, so they works as a RAID on a network level), unlike in the case with the failed RAID and one big node.
