I'm a new user intersted by ether universe. But i am ver surprised by difficulty to join the blockchain network. I'm working with Ubuntu 16.04, i7-2630QM CPU @ 2.00GHz, 8Go RAM and Seagate ST95005620AS. 100ko/s in upload, 800ko/s in download.
History: I started to sync with geth (go implementation). After one week of syncing and 2'000'000 block left to sync, my syncing block rate was 1 block every 30s. After read some topics, i deleted my chaindata folder and restart syncing with parameters --fast and --cache=2048. After two day of scync, same 1 block every 30 seconds. I deleted chaindata again and restart ... now i have this issue:
err="leveldb/table: corruption on data-block (pos=783749): checksum mismatch, want=0xe2cae6af got=0xcc97e598 [file=027201.ldb]"
I have two question:
- It is normal to be very painful to sync ?
- The corruption error if from logicial or hardware problem ?
