Download snapshot cannot be recognized

[shora0]

Why is the snapshot I downloaded from https://publicnode.com/snapshots#polygon unable to recognize the snapshot’s blocks and needs to be resynchronized?

config.toml is set:
“db.engine” = “pebble”
"state.scheme" = "path"

It does not seem to pick up this setting in the config toml.

[shora0]

Bor client version: v1.5.5

Heimdall client version: v1.2.0

OS & Version: Ubuntu 20.04.6

Environment: Polygon Mainnet

Type of node: Sentry

[manav2401]

Did you download the pebble and path snapshot or the old level + hash one?

I believe you haven't put the snapshot to correct location causing this. That's why bor isn't able to find anything and starting to sync from scratch. Can you mention what's the location of your snapshot and what's your datadir set in bor config?

Also, do you see any State scheme set by user logs? What does it say?

[shora0]

The location is correct. Your base snapshot is leveldb data and partly pebble data. After decompression is started, the ancient link segment is extracted. Please set --datadir.ancient to the correct path. Only basic snapshots can regenerate pebble data for normal synchronization. Otherwise block 2236 will encounter a bad block and cannot be synchronized.

Is this solved @shora0 ?

[shora0]

Only the base snapshot of https://publicnode.com/snapshots#polygon can be downloaded and then resynced to work properly.

Note - either symlink the datadir or put the data there. Make sure necessary ports are open and that bor has permission to access - heimdall needs to be synced first.

[shora0]

The configuration is the same as yours, and the directory is the same. If you use basic snapshots and partial snapshots, an error message "The ancient link segment has been extracted, please set --datadir.ancient to the correct path" will be reported. Bol cannot run. Without a snapshot, block 2239 cannot be skipped at all and synchronization is always stuck.

[shora0]

This problem occurs during synchronization

[prostghost]

@shora0 Did you solve this problem?

[shora0]

I can synchronize blocks but this error is reported. What is the problem?

Can you please try to upgrade to bor 2.0.0
