Andrzej Bialecki commented on SOLR-11665:
------------------------------------------
This patch contains the following improvements and fixes:
* failures at any phase in the process are followed by an explicit cleanup,
which removes partially constructed shards
* sub-shards are now created with the same number of replicas per replica type
as the parent type - previously only NRT replicas would be created.
* fixed a bug in coreName construction so that the new cores follow the same
naming pattern per replica type as the parent shards
* SplitShardCmd now first checks the amount of available disk space on the
parent shard leader's node to ensure that the actual index splitting has enough
disk space to proceed.
* unit test changes, and a test that verifies the correct number of replicas
per type in the new sub-shards.

> I do see some problems when doing split shard but there are no available
> nodes for creating replicas ( due to policy framework )
> - The patch contains a test, in which sub shard stay in CONSTRUCTION state
> forever.
> - Shard which get split, stay in inactive state forever and subshards are not
> created
