Shard recovery is the process of initializing a shard copy, such as restoring a
|
|
primary shard from a snapshot or creating a replica shard from a primary shard.
|
|
When a shard recovery completes, the recovered shard is available for search
|
|
and indexing.
|
|
|
|
Recovery automatically occurs during the following processes:
|
|
|
|
* When creating an index for the first time.
|
|
* When a node rejoins the cluster and starts up any missing primary shard copies using the data that it holds in its data path.
|
|
* Creation of new replica shard copies from the primary.
|
|
* Relocation of a shard copy to a different node in the same cluster.
|
|
* A <<snapshots-restore-snapshot,snapshot restore>> operation.
|
|
* A <<indices-clone-index,clone>>, <<indices-shrink-index,shrink>>, or
|
|
<<indices-split-index,split>> operation.
|
|
|
|
You can determine the cause of a shard recovery using the <<indices-recovery,recovery>> or <<cat-recovery,cat recovery>> APIs. |
