Description
http://thread.gmane.org/gmane.comp.file-systems.ceph.devel/6777/focus=6856
User reports iozone random read/write (-i 2) runs fail with record length 4 (actually run in automatic mode, but that seems to be the trigger).
Our regression tests only run a handful of iozone sizes, 4k isn't one of them.
1. Add a 4k block size run to regression tests.
2. Add iozone random read/write tests (-i 2) to regression tests (same block sizes as for the current ones)?
I think the earlier reason to avoid too many iozone tests was that they were quite slow. Watch for the total running time..
And finally, once the qa is in place, fix all the bugs.
