Hi,
I am running Cassandra 2.1.10 and noticed intermittent
DirectoryNotEmptyExceptions during repair. My cassandra data drive is
reiserfs. I noticed that on reiserfs wiki site
https://en.m.wikipedia.org/wiki/ReiserFS#Criticism, it states that unlink
operation is not synchronous. Is that the reason for the exception below:
ERROR [ValidationExecutor:137] 2015-10-13 00:46:30,759 CassandraDaemon.java:227
- Exception in thread Thread[ValidationExecutor:137,1,main]
org.apache.cassandra.io.FSWriteError: java.nio.file.DirectoryNotEmptyException:
