Linux ZFS & resizing single disk pool

In a virutal enviorment I have found that I still like a lot of the features of zfs, but I do not end the RAID functionaily. With that I had the need to expand a single disk zpool due to space issues. In the past, we simply just added a second disk creating a RAID 0. But I knew there was a better way. ZFS on Linux does support resizing or autoexpand on a single disk zpool. To do this, do the following steps.

Create or Set your zpool with autoextend on (it defaults to off)
```
 zpool set autoexpand=on tank
```
Via your Virtual Host tools, extend the disk in question to the size you need.
Now on your VM, get the disk name in your zpool
```
 zpool status
```
Run parted on that disk to resize the partition.
```
 parted /dev/sdb
```

Now simply use resizepart and it will default to the max

 (parted) resizepart                                                       
 Partition number? 1                                                       
 End?  [X.XGB]?                                                           
 (parted) quit   

Now that you completed that, you need to just tell the zpool to expand. You can do this online by running the following command.
```
 zpool online -e tank sdb
```
You should now notice that your partition is now larger
```
 df -h
```
