New blog post, "Updating The File Server to FreeNAS 11," on Kicking The Bit Bucket.
Over the weekend I took the time to upgrade my file server from FreeNAS 9 to FreeNAS 11 (version 10 was an unreleased clusterf*ck). The big challenge wasn’t upgrading FreeNAS in place for the first time (I’ve done past upgrades by installing FreeNAS on new 16GB SanDisk Cruzer Fit flash drives). That part went quite smoothly. The big challenge was changing something that could jeopardize my data. By replacing the six-drive RAIDZ3 vdev with three two-drive stripped mirror vdevs, I had to destroy my data, restore my data from backup, and hope that my data wasn’t corrupted in the process.
