Hi All, I'm working on an ES upgrade from v0.20.5 to v1.2.1 I tested in a 2 node cluster, 3 indices, ~4 million docs, 18G file sizes, 20 shards, 1 replicas However, after bumping the version and reboot the cluster, I kept on seeing some shards are damaged. The ES log said: Caused by: org.apache.lucene.index.CorruptIndexException: did not read all bytes from file: read 451 vs size 452 (resource: BufferedChecksumIndexInput(MMapIndexInput(path="/18/index/_195c_i.del")))
This badly blocked the version upgrade in my case. Could you any one point me the reason of this issue? Lots appreciate to your help!
