[daxionga]

I run my IPFS daemon node with docker
today,I don't know why my IPFS node has dirty data, it can't start up, and always get this error now

Error: constructing the node (see log for full detail): error loading filesroot from DAG: block was not found locally (offline): ipld: could not find QmRwA5Sn3Ubf9hYoP3sSchy3Cb9YRifXMMkWxW5aUowUmq

but I also want to keep the data that has no problem, how can I do it
