While working on my most recent project i tested an interesting ZFS feature: writeable snapshots aka “clones”.
While testing i came to the conclusion that with the help of clones oracle databases (and, of course – other databases as well) can be clones extremely fast with almost no disk space required. So i tested it.
Read on for the results…
This is part III of my most recent project named “Building a custom and cheap storage server yourself”. Part I can be found here and Part II here.
Part II left with a current status of a crashing machine during high I/O loads.During the previous weeks i tried to solve the stability problems. And finally: we solved them!
This third part is about our problems, what caused them and how we finally solved them….
Just a short note from myself:
Last week i successfully completed all requirements to become an
Oracle Certified Trainer
Preparing for the course took all my time so there was little time left to write in my blog. Beside preparing for the trainer tests i worked a lot on my other project: building a cheap custom storage yourself.
