# swift-object-reconstructor(1)

OpenStack Swift EC object reconstructor

## NAME

swift-object-reconstructor - OpenStack Swift EC object reconstructor

## SYNOPSIS

**swift-object-reconstructor** *CONFIG* \[*options*\]

## DESCRIPTION

Daemon for reconstruction of EC objects. Once a pair of nodes has determined the need to replace a missing object fragment, instead of pushing over a copy like replication would do, the reconstructor has to read in enough surviving fragments from other nodes and perform a local reconstruction before it has the correct data to push to the other node.

## OPTIONS

- **-h**, **--help**

  Show this help message and exit

- **-d** *DEVICES*, **--devices**=*DEVICES*

  Reconstruct only given devices. Comma-separated list. Only has effect if --once is used.

- **-p** *PARTITIONS*, **--partitions**=*PARTITIONS*

  Reconstruct only given partitions. Comma-separated list. Only has effect if --once is used.

- **-v**, **--verbose**

  Log to console

- **-o**, **--once**

  Only run one pass of daemon
