The default command is `ec.encode -fullPercent=95 -quietFor=1h`. It will find volumes at least 95% of the maximum volume size, which is usually 30GB, and have no updates for 1 hour. +If the volume is replicated, only one copy will be erasure encoded. All the original copies will be purged after a successful erasure encoding. + Note: One collection can contain both normal volumes and erasure coded volumes, with write requests going to normal volumes. ### Data Repair
