> We had several cases where the the manifest file would get corrupted when
> doing power reset tests or iLO resets to mimic power failure scenarios,
> ungraceful resets, kernel panics etc. It wasn't clear at the time where the
> problem was, but I think the data below shows that Cassandra is missing an
> fsync call to the manifest file prior to closing it. This particular stack
> trace from below is on Cassandra 1.2.4.
> The trace was captured using strace options:
> strace -f -p 2200 -e trace=open,close,write,fsync,fdatasync,rename
> [pid 9710]
