I restored my miner node with 9/15 snapshot which Phala official provided.
But when I’m syncing pherry, I met many errors that I can’t start mining,
finally I fixed them.
here’s what I’ve done:
- Extract and place extracted files to correct place as official FAQ described
- Delete
chains/khala/dbfolder, this part is corrupted that can’t be used, you have to re-sync it -
cd ~ && wget https://github.com/paritytech/polkadot/releases/download/v0.9.9-1/polkadot && chmod +x polkadotdownload Parity’s Polkadot - MAKE SURE YOU HAVE STOPPED
khala-nodeandpherry,pruntimedon’t need to be stopped -
./polkadot --chain "kusama" --base-path /data/khala-node/polkadot --pruning=archive- if you’re using docker image or solo-mining script, you should
sudo ./polkadot --chain "kusama" --base-path /data/khala-node/polkadot --pruning=archive - change
/data/khala-nodeto yourkhala-nodedata folder, and/polkadotmust be the end of the path, e.g. if you’re using solo-mining script, you need to change the command tosudo ./polkadot --chain "kusama" --base-path /var/khala-dev-node/polkadot --pruning=archive
- if you’re using docker image or solo-mining script, you should
- When it start, you have to waiting some minutes, then you can see it sycing data, just let it run about a minute, then
Ctrl + Cto stop it - The syncing should start ~9000000 block height, because we’re starting from the snapshot, if start from 0, check
--base-pathyou must give an incorrect path - Restart
khala-nodeandpherry- You must add
--fetch-blocks 512topherryif you’re using official Docker Image add it toEXTRA_OPTSlike this-e EXTRA_OPTS="-r --parachain --collator-ws-endpoint=ws://localhost:9944 --fetch-blocks 512", solo-mining script should has been fixed by Phala team, just upgrade it - I suggest start
pherrywhen you confirmkhala-nodeis fully synced.
- You must add
我先用官方提供的全量备份恢复我的节点，但是同步的时候遇到了各种问题，折腾了一宿分享一下我的做法，目前我这边的节点已经没问题开挖了
- 先按官方的教程把备份给恢复了
- 把
chains/khala/db目录删了，这部分彻底坏了，重新同步一次一两小时，等等问题不大 - 运行
cd ~ && wget https://github.com/paritytech/polkadot/releases/download/v0.9.9-1/polkadot && chmod +x polkadot下一个官方的波卡 - 进行后边操作之前确保把
khala-node和pherry给停了,pruntime可以不关 - 运行
./polkadot --chain "kusama" --base-path /data/khala-node/polkadot --pruning=archive- 要是用 docker 或者官方那个 solo 挖矿跑的要加
sudo像这样sudo ./polkadot --chain "kusama" --base-path /data/khala-node/polkadot --pruning=archive - 把
/data/khala-node改成你那边存数据的路径，结尾必须是/polkadot，比如你用官方那个 solo 挖矿脚本，你就改成sudo ./polkadot --chain "kusama" --base-path /var/khala-dev-node/polkadot --pruning=archive
- 要是用 docker 或者官方那个 solo 挖矿跑的要加
- 等几分钟，开始应该卡一会，过会就出来在同步的信息，而且区块差不多是900多万，如果从 0 开始的，说明你
-base-path路径给错了，让他跑一两分钟按Ctrl + C退出 - 重启
khala-node和pherry- 必须给
pherry的启动命令加上--fetch-blocks 512，如果你用官方的 Docker 镜像，那就得加到去EXTRA_OPTS比如这么写-e EXTRA_OPTS="-r --parachain --collator-ws-endpoint=ws://localhost:9944 --fetch-blocks 512"，官方的 solo 挖矿脚本已经给修了，下最新版就行 - 最好是确认
khala-node同步完了再启动pherry
- 必须给
另外，之前有老哥说 finalize 0 不动的问题，我这里没遇到，就同步完了放着十来分钟自己就好了，还不行重启一下 khala-node 之后再等等就行
