[Tech Preview] Hashstore backend for storage nodes

[Alexey]

@Roxor

Now that I know they have a utility that can rebuild the hashtables from the logs, I’m much more comfortable with the migration.

It even has been used at least once:

Hashstore error preventing node restart

It has been merged. You can build it with latest go: git clone git@github.com:storj/storj.git && cd storj go install ./cmd/write-hashtbl Then in the ~/bin subfolder there should be a binary write-hashtbl. You may see the help ~/bin/write-hashtbl --help the easiest way is to just use the default flags and pass it one of the store directories, so like ~/bin/write-hashtbl /mnt/storj/storagenode/storage/hashstore/12L9ZFwhzVpuEKMUNUqkaTLGzwY9G24tbiigLiXpmZWKwmcNDDs/s0 and do the same with /s1 …

And you can use this method if you do not want to install GO:

Nobody has submit such PR so far, I would like to invite you to be a first one Right now you can build this tool by installing GO for Windows, then use then run like described in the same post cd X:/storagenode/storage/hashstore/12L9ZFwhzVpuEKMUNUqkaTLGzwY9G24tbiigLiXpmZWKwmcNDDs/s0 mv meta meta.bak mkdir meta cd meta ~/bin/write-hashtbl X:/storagenode/storage/hashstore/12L9ZFwhzVpuEKMUNUqkaTLGzwY9G24tbiigLiXpmZWKwmcNDDs/s0 But maybe easier to use docker approach mentioned ea…
