Alexander L updated LUCENE-9867:
--------------------------------
Description:
Failed segment merge caused by "No space left on device" can't be recovered and
Lucene fails with CorruptIndexException after restart. The expectation is that
Lucene will be able to restart automatically without manual intervention.
We have 2 indexing patterns:
* Create and commit an empty index, then start long initial indexing process
(might take hours), perform a second commit in the end
* Using existing index, add no more than 4k documents and commit after that
Seems like the first pattern might cause more problems, but we witnessed
similar situation for the second pattern, although it was a bit different -
caused by {{OutOfMemoryError: Java Heap Space}}, and missing {{_q.cfe}} file
produced only {{FileNotFoundException}}, not {{CorruptIndexException}}. Please
let me know if we need a separate ticket for that.
Lucene version: 8.5.0
Java version: OpenJDK 11
OS: CentOS Linux 7
Kernel: Linux 3.10.0-1160.11.1.el7.x86_64
Virtualization: kvm
