Geeking out big time with ZFS and FreeNAS

I’ve been using FreeNAS for over a year now and it is an awesome piece of software to turn an old PC into a Network Attached Storage device.  I’ve been running it on two old PCs, one full of old TV Shows and Movies I ripped from DVD’s to the hard drive.  This is for the boys, I was getting sick of them leaving piles of discs on the floor in front of the DVD player.  They were getting more scratched all the time so I backed them up to the FreeNAS server and they use XBMC (xbox media Centre) on another PC hooked up to the TV.

The other FreeNAS box has all my important files I’ve collected over the years.  But my most important files are backed up on my Drobo, which is awesome!

The Drobo is another NAS that is hooked up to my Mac Mini and is all set to share upto 16 Terabytes of data (whenever my Drobo is expanded to that size).  The Drobo is cool because it can be expanded by replacing the smaller drives in it with larger ones and it will keep growing.  Currently I have four 1 Terabyte drives in my Drobo which gives my about 2.7 Terabytes of protected storage.  If one of the drives in the drobo dies my data is still ok and all I have to do is replace the bad drive and away I go…

Now the problem is when I upgrade the drives in the drobo I’m left with spares that need to be used!  So I’ve decided to get into the Nightly build FreeNAS server which supports ZFS!

ZFS is an amazing file system that can be used as a wrapper around many pools of vdevs of drives.  The vdevs can be configured in single or RAID combinations and in Raid 5 & 6 can even be expanded similarly to a Drobo!  But unlike the Drobo Raid 5 & 6’s like all the drives to be the same size otherwise you waste a lot of storage space.

So I thought I might as well use my spare drives configuraed as JBOD (just a bunch of drives) but FreeNAS (official release 0.69) doesn’t support the size of the JBOD properly and you don’t get the use out of them.  So I decided the best choice is to use the nightly build and stripe the drives together within a vdev under ZFS.  Another bonus of ZFS is it does tests for bitrot and ensures your data is maintained.  The only real problem I see if that ZFS isn’t very mature yet.  It was written for Solaris and is ported over to FreeBSD which FreeNAS is based on.  But it has come a long way now and I’m having a lot of success so far running this version of FreeNAS so far.

My plan for now is to use the FreeNAS box I use for the boys TVShows & Movies.  I’m using a bunch (7 total) of old drives striped toggether in a ZFS vdev and added to a ZFS pool called backuppool0.  This pool will be rsynced nightly from my main drive which (for now) is a 1 terabyte drive that is on it’s own as a UFS/(EFI GPT) formatted drive.  It used to be rsynced nightly onto two 500Gig drives, a movie section on one 500Gig drive and the TV Shows on the other 500 Gig drive.  But since I’ve decided to rip the my TV shows that I want to watch and put those on my drives so that I can access them with a click of a button the 500 Gig drive is getting too full…

ZFS to the rescue!

I’ve been recording most of my experiments so far and I’m currently rsyncing my 1 Terabyte drive to my ZFS backuppool0:  Here’s the data I’ve collected so far.  Hopefully other FreeNAS experimenters would like the info (if they can find this page…)

Important things I’ve found out recently with FreeNAS and ZFS.  Make sure that you do the format part with each drive you are going to use in your ZFS vdev.  If you don’t I’ve found that they come up with some GPT errors which I couldn’t fix without doing the ZFS format.  Disks|Format (choose the Disk) then in the File System drop down box be sure to select ZFS storage pool device.  Then you will end up with a nice clean ZFS system…

We now have ad14 as a 1TB drive. This has data on it as a stand alone drive which must be copied to BackupPool first then can be added to the new pool0

which will be a stripe of this 1TB drive and a 500 G drive. They will be Rsynced with the backup-pool nightly for redundancy.

Rsynch transfer rate is about 150 Mb/s
