Hrishikesh Gadre commented on SOLR-8587:
----------------------------------------
[~shaie] I ran into a similar problem (NoSuchFileException for the segments
file) while working on Solr backup/restore. This problem can be avoided by
using the following trick implemented in ReplicationHandler.
https://github.com/apache/lucene-solr/blob/7794fbd13f1a0edfff8f121fb1c6a01075eeef6a/solr/core/src/java/org/apache/solr/handler/ReplicationHandler.java#L537-L542
I see that LukeRequestHandler is not implementing similar strategy.

My guess is that if we change LukeRequestHandler to implement a strategy
similar to ReplicationHandler, it should fix the problem. Although I don't
fully understand why is that the case. [~yo...@apache.org] [~thetaphi] you have
any idea?

> Having the index's segments file name returned by CoreAdminHandler STATUS can
> be useful. The info I'm thinking about is the segments file name and its
> size. If you record that from time to time, in a case of crisis, when u need
> to restore the index and may not be sure which copy you need to restore, this
> tiny piece of info can be very useful, as the segmentsN file records the
> commit point, and therefore what you core reported and what you see at hand
> can help you make a safer decision.
> I also think it's useful info in general, e.g. probably even more than
> 'version', and it doesn't add much complexity to the handler or the response.
