Please note that this website is currently a work in progress! Lots of interesting data and statistics to come.
I am waiting to see if I can bring home a server from work that may be decommissioned soon. I want to play with FreeNAS Corral outside of my live home server, the vm and docker integration sounds awesome.
EDIT: mistype
God damn it. Just moved off all in one freenas/VMWare to unraid.
Now might have to move it all back, I do miss the safety feeling of ZFS.
Just a point of clarification. The information about ZFS's Log drive isn't exactly correct. It is a common mistake but really the Log device is actually referred to as a ZIL or ZFS Intent Log.
The purpose of the ZIL is more of a journal for writes only (they have no impact on reads, that's the job of the L2Cache/Cache section in the FreeNAS window). The data for writes is still kept in memory, however without the ZIL the data has to be written to the ZFS data store before it is acked. With a ZIL the acks occur once the ZIL device has committed the write. The information still exists in RAM and is eventually pushed to the datastore from RAM, but the ZIL's purpose is to make sure a write isn't lost (as an example if power is lost then the write in memory is wiped, but the ZIL can replay the write and the data is recovered). Writes still occur from RAM to the data store during normal operation. The ZIL is only used in the event that there is a failure, and the data that was in RAM is lost.
It's a tricky and nuanced concept, so it is easy to think about it in the wrong way.
Having said that... there are some SAN providers that use ZFS as their backend file store, and they are super fast (Tegile).
I was deeply confused for a minute. 10-RELEASE is out (and it's called Corral). Hell yeah!
I'm itching to build a FreeNAS based system that can outperform my QNAP TS419, in a similar small footprint. Any chassis suggestions?
How solid is Corral right now? I tried to run the FreeNAS 10 beta about two months ago and ran into some issues (mostly polish). Did they get that all squared away?
