@puppies where can I find your failover script?

[rnglab]

Thanks betax and rng.  Be careful.  I forgot to mention the first thing it will do is kill any running witness_node on your box so that it can start a new one in a screen called witness.  I would not suggest running it on your main production witness until it has been much more thoroughly tested.

Thanks puppies, I'll help testing. It seems that you also improved fork detection  : )

Thanks for the great work and  for the responsible caution statement.

I've switched witness account from  "1.6.33"  "bts-bitshares-argentina" to "1.6.45" "rnglab"

Please downvote bts-bitshares-argentina and vote for rnglab. Thanks

witness "1.6.33" is back, sorry for the delay

Update: failover script based on update_witness didn't work because witness_node process died on both servers after the fork. Checking logs now

My newest version of failover script should restart witness_node and cli_wallet in case of crash, or witness production falling below 50%.  Unlock the wallet, and switch signing keys if blocks are missed.  The first 3 times it restarts it will attempt a --replay-blockchain to get back on a majority fork.  If that doesn't work it will try a --resync-blockchain.

At least thats what I expect it to do.  I still need to test it a bit more.

great puppies! that's what we need. I can help testing if you want.

Both witness nodes crashed around 10 minutes after the fork. Seednode also crashed a few minutes later. Each on a different VPS.

All witnesses may need to replay the blockchain to get back in sync.  There seems to be an issue that can cause things to get out of sync.

delegate.taolje is syncing nicely now, need some vote for servicing network

No, oct 5 was just an example. I found at the source the genesis.json, but I could not find seed node ?

it should find the seed node and use the genesis with no arguments

Code: [Select]

./witness_node
Is supposed to just work, no genesis file or seeds are needed. This is different than the testnet where you had to give it seed nodes and genesis.json.

also, witness maqifrnswa needs votes
