# Import existing sector data
When we want to migrate the sector storage directory that has been completed by other computing power component solutions to venus-cluster
, we only need to use venus-sector-manager
to import and update the corresponding configuration file.
# Import and verify
Note: Both import and validation need to be done without the venus-sector-manager daemon
started.
# import
venus-sector-manager
provides an import tool called storage attach
, which is used as follows:
venus-sector-manager util storage attach --verbose --name={storage name} <path>
in:
name
is an optional parameter;<path>
is the storage path, which is converted to an absolute path during import.
For the meaning of name
and <path>
, please refer to Common.PersistStores (opens new window).
For example, we use
venus-sector-manager util storage attach --verbose --name=a -v ./mock-tmp/remote
Usually a log similar to the following is produced:

At this time, the directory import has been completed, and the location information of all sectors has also been recorded.
We can complete the import by copying and filling the final output example configuration into the configuration file of venus-sector-manager
.
# reimport
If we find that the information filled in when importing is wrong, such as --name
is misspelled, then we only need to re-use the correct information to complete the import process once.
The location information of the sector will be overwritten and updated.
# sealed_file separated from cache_dir
Some computing components allow sealed_file
and cache_dir
to be on different storage instances, in which case regular import may fail to locate sector files properly.
In this case, you can enable the split scan mode by adding the command line parameter --allow-splitted
. In this mode, the sealed
folder and the cache
folder are scanned separately for sectors that meet the naming rules path, and record the positioning information respectively.
At this point, the log will look similar to:
