Pushkar Raste commented on SOLR-9310:
-------------------------------------

I went through logs in the failed test email notification but those are truncated. Where can I look at the entire build.log for the test. 

Only thing I could think of at this point is data directory could get deleted while a node is brought down, since data directory is created in {{temp}}. Upon restart replica would have no frame of reference and will have to fall back on replication.

> I found that Peer Sync fails if a node restarts and documents were indexed while node was down. IndexFingerPrint check fails after recovering node applies updates. 
> This happens only when node restarts and not if node just misses updates due reason other than it being down.
> Please check attached patch for the test.
