[BUG] LOTUS_ENABLE_CHAINSTORE_FALLBACK=1 invalid

[rickiey]

When I set LOTUS_ENABLE_CHAINSTORE_FALLBACK=1 and then start lotus daemon:

$ lotus daemon --halt-after-import --import-snapshot complete_chain_with_finality_stateroots_latest.car            

$ cat /etc/systemd/system/lotus-daemon.service

The error is suggesting you dont have the state.
Are you reimporting a snapshot on a clear datastore? If not - you need to make sure that the epoch of the last block is no later than the epoch of the first block the snapshot contains.Or if there isn't much historic state accesses, LOTUS_ENABLE_CHAINSTORE_FALLBACK=1 should work

I have removed datastore/chain, and reimporting https://fil-chain-snapshots-fallback.s3.amazonaws.com/mainnet/complete_chain_with_finality_stateroots_latest.car;
It is normal in v1.5.3, An error occurred in v1.6.0: #5975, magik6k fixed it: #6003, Then when I re-imported an error occurred: block not found

I use v1.9.0rc1 to build lotus, and start with LOTUS_ENABLE_CHAINSTORE_FALLBACK=1 env. I got 'block not found' error too. I want to know if the lotus node will pull missing state/receipts from the network with that env. And if true, why it doesn't work?

v1.10.1 Still fail
