I believe the following witnesses are on the minority fork and need to --replay-blockchain:
bts-bitshares-argentina
bue
cyrano
delegate-1.lafona
elmato
fox
mr.agsexplorer
roadscape
triox-delegate
xeldal
The operators of these witnesses have done nothing wrong. We managed to capture the event which caused the split, and we should be able to debug the issue.
EDIT: bts-bitshares-argentina went down ~10 minutes after the fork, and roadscape was down for a while before the fork.
