StateDb does not have PRUNING_MODE

[tugytur]

When upgrading a node from 0.9.21 to 0.9.22 I get the following error on startup:

Also tried again with --unsafe-pruning \, issue is still there

I have faced the same issue.

My node was previously synced with the flag sync=Warp and after binary migration to v0.9.22 the following error is shown:

Reverting binary to previous version v0.9.21 the node starts as normal.

Sadly there was a bug before and the code is now more strict. You would need to resync with warp sync on 0.9.22. Sorry for the inconvenience!

[bkchr]

Okay, there is a problem with warp sync as well: paritytech/polkadot#5556

[tugytur]

Okay, there is a problem with warp sync as well: paritytech/polkadot#5556

I started syncs from scratch for paritydb and rocksdb.
Will make them available on https://parasnaps.io/ as soon as it's synced.

[tugytur]

@bkchr we are syncing since yesterday for Polkadot and Kusama.

Kusama seems a bit slower, but Polkadot is way slower and is syncing only with ~8-15 bps.
Don't know if this is a bug or something drastically changed.

The specs of the VMs are the same as for the Validators (also pass the benchmark tests).

[bkchr]

@tugytur What parameters do you run your node with?

[tugytur]

@bkchr the only differences are the chain and db.

ExecStart=/usr/local/bin/polkadot \
        --name "X" \
        --pruning 1000 \
        --no-mdns \
        --public-addr=/ip4/X.X.X.X/tcp/30333 \

        --ws-port 9944 \

        --base-path=/var/blockchain

Kusama with paritydb is synced after almost 48h
Kusama with rocksdb after ~50h is at target=#12771417 (50 peers), best: #12755968

Polkadot with paritydb after ~50h target=#10391605 (50 peers), best: #2350890
Polkadot with rocksdb after ~50h target=#10391611 (50 peers), best: #2938044

[bkchr]

This is fixed.
