more usable space compared to replicated pools, but they do that for the price
of performance.
For comparision: in classic, replicated pools, multiple replicas of the data
For comparison: in classic, replicated pools, multiple replicas of the data
are stored (`size`) while in erasure coded pool, data is split into `k` data
chunks with additional `m` coding (checking) chunks. Those coding chunks can be
used to recreate data should data chunks be missing.

Creating EC Pools
^^^^^^^^^^^^^^^^^
You can create erasuce coded (EC) through using the `pveceph` CLI tooling. As
EC code work different than replicated pools, planning a setup and the pool
parameters used needs to adapt.
Erasure coded (EC) pools can be created with the `pveceph` CLI tooling.
Planning an EC pool needs to account for the fact, that they work differently
than replicated pools.
The default `min_size` of an EC pool depends on the `m` parameter. If `m = 1`,
the `min_size` of the EC pool will be `k`. The `min_size` will be `k + 1` if

Adding EC Pools as Storage
^^^^^^^^^^^^^^^^^^^^^^^^^^
You can also add an already existing EC pool as storage to {pve}, it works the
same as adding any `RBD` pool but requires to pass the extra `data-pool`
option.
