I've spent weeks syncing a full Geth node, but for part of the way (about 100k blocks), I mistakenly neglected to set the
gcmode=archive flag. So, for these blocks, the state tries are gone and I am unable to run traces.
Is there a way to have Geth rerun these blocks to regenerate and archive the state tries? It would be nice not to spend another few weeks syncing the node again from scratch.
