@ -359,6 +359,31 @@ A directory can be in one of the following states::
- `syncing`: The directory is currently being synchronized
- `failed`: The directory has hit upper limit of consecutive failures
When a directory is currently being synchronized, the mirror daemon marks it as `syncing` and
`fs mirror peer status` shows the snapshot being synchronized under the `current_syncing_snap`::
$ ceph --admin-daemon /var/run/ceph/cephfs-mirror.asok fs mirror peer status cephfs@360 a2dc7784-e7a1-4723-b103-03ee8d8768f8

The mirror daemon marks it back to `idle`, when the syncing completes.
When a directory experiences a configured number of consecutive synchronization failures, the
mirror daemon marks it as `failed`. Synchronization for these directories is retried.
By default, the number of consecutive failures before a directory is marked as failed
