I just finished my server migration and am now serving up CIFS shares from a 4TB RAID1 zpool. This site is served via a native FreeBSD jail which also handles my email. It was a bit of a bumpy migration as I suspected my hardware had gone bad. My original ‘plan’, was to install two new 4TB NAS disks, install Ubuntu 14.04 LTS, install ZOL, and transfer the data to a shiny new zpool before my existing raid died (spinning for 4+ years). Things went fine until a few hours after the transfer completed and then the box started locking up. I assumed it was a hardware problem as I had rewired all the SATA connections and swapped some memory.
I tried swapping the memory back, moving it to a new bank, fiddled with the bios, but nothing fixed the problem. Then I thought I’d try the latest FreeNAS just to see if it truly was the hardware and besides… It has zfs and the zpool format should be compatible so why not? I threw in a FreeNAS-18.104.22.168 CD and booted it up. I manually imported the zpool, fixed up the mountpoint’s, then exported and imported using the GUI. That was 3 days ago.
I think I’m going to like this FreeNAS.

I thought I’d throw in this snapshot for a bit of humor… Back in 2010 when I was putting this box together, I didn’t have any drive rails and it was late on a Sunday so I manufactured my own drive rails out of some scrap oak I had in the garage. I had totally forgotten about these until I did this migration.
