# NAME #

**pmempool-sync** -- Synchronize replicas or their parts within a poolset.

# SYNOPSIS #

```
pmempool sync [options] <poolset_file>
```

NOTE: Only the poolset file used to create the pool should be used
for syncing the pool.

# DESCRIPTION #

The **pmempool sync** command synchronizes data between replicas within
a poolset. It checks if metadata of all replicas in a poolset
are consistent, i.e. all parts are healthy, and if any of them is not,
the corrupted or missing parts are recreated and filled with data from one of
the healthy replicas.

##### Available options: #####

`-d, --dry-run`

: Enable dry run mode. In this mode no changes are applied, only check for
viability of synchronization.

`-v, --verbose`

: Increase verbosity level.

`-h, --help`

: Display help message and exit.
