Is there any option to fix it without full resync?

Afaict that shouldn't have been an actual crash, you're just getting bad blocks on the network which your node should be ignoring? Kovan has just gone through a hardfork and you are on the right version of parity to continue syncing with the correct side of the chain.

How exactly are you running your node? Are you using --chain kovan or manual chainspec to connect to kovan?

jam10o-new · 2019-05-15T13:26:28Z

Here are the details of the fork #10628 (comment) and if you still are having trouble, you can always manually use the chainspec you can find in this repo at ethcore/res/ethereum/kovan.json

It appears you are somehow still using the old version of the chain specification (you are expecting an old validator).

varasev · 2019-05-15T13:27:01Z

Seems the reason is that a new bootnode is not fully synchronized yet: https://kovan-netstat.poa.network/

The old bootnodes have no new chain spec, so they are not working at the moment: https://kovan-stats.parity.io/

@APshenkin it looks like you'll have to wait for more peers or bootnodes running up to date versions to come online.

@varasev I've passed on that our bootnodes appear to still be running the old chainspec. That's probably a mistake. (cc @gabreal?)

I've passed on that our bootnodes appear to still be running the old chainspec. That's probably a mistake.

Yes, they should have been updated as well, but seems they have an old spec.

Also, we had to restart our bootnode right after the fork, for that reason it's still in sync.

varasev · 2019-05-15T13:57:28Z

@APshenkin could you repeat once more? Now, our node is fully synchronized.

@APshenkin a resync might be unavoidable unfortunately, I understand that might be frustrating with a fat-db archive node. You might be able to rewind with parity --chain=kovan db reset [number of blocks] in order to remove the bad chain head and try to continue sync.

*edit: you don't need to be in beta to try a reset. It was added in 2.3

@APshenkin also try with the following CLI-flags: --reserved-only --reserved-peers=./reserved_peers

where the reserved_peers file should contain this line: https://github.com/paritytech/parity-ethereum/blob/e04a2f926acd7ced096eb8a40c01821731ebd777/ethcore/res/ethereum/kovan.json#L5384

Generally speaking you should be able to ignore bad block detections - I would try adding an up to date node to your reserved peers as recommended above..

@joshua-mir

Looks like that after db reset there is other issue (not a problem with bad blocks)

before reset blocknumber was 10960440

The new block after hardfork is 10960441 that alerts on startup.

I run this command: parity --chain=kovan reset db 10

and it successfuly reset to block 10960430

Now when launching (with reserved peers also) parity node takes 10960441 block on startup (I don't know from where, maybe some cache) and try to insert it. But there is no 10960440 block more.

Also when running with reserved peers after some time parity starts prints logs about syncing, but it's stuck on 10960430 block

@seunlanlege any ideas?

jam10o-new · 2019-05-15T15:54:22Z

@APshenkin it was either a reset or resync, unfortunately.

APshenkin · 2019-05-15T17:02:56Z

@joshua-mir

So, after several hours syncing wasn't started after block reset

Looks like block reset feature is not working as expected, or I don't understand why it can't start sync.

Currently I had removed --reserved-only --reserved-peers=./reserved_peers CLI flags and have only 2 peers and no sync blocks info

maybe I can provide any detailed logs to help you to fix it?

It's not a problem to resync arhive node for kovan (it's not so big)

But if somebody will faced similar issues in live network then resync will be painable for them (1-2 month to sync again)

jam10o-new · 2019-05-15T17:04:51Z

Pinged Seun above, who implemented the feature and might have a better idea about what's going on.

seunlanlege · 2019-05-15T17:35:00Z

hey @APshenkin, the error your facing is a known issue #9910 that plagues the way blocks are imported. For now, I would advise a resync.

stephgosling · 2019-05-15T23:35:55Z

we saw the same, 2.5.0 instances on kovan panicked in that way, upgrading to 2.5.1 and retaining data they also wouldn't proceed past 10960440. Deleting the chain data and restarting our instances all successfully resynced. This was annoying for us as this appeared to side-step our check for their uptodateness
