Upgrading hard drives in your NAS question

to the best of my knowledge rebuilding arrays are incredibly stressful for the remaining drives and doing it multiple times risk drive failure.

im actually not sure if hexos/truenas will automatically increase pool size if you replace the smallest drive with a bigger drive. it would be great if it does 

I am a complete noob to this realm so please be patient. 

In a previous post on my hardware I talked about starting with hard drives that I have laying around and upgrading as I can afford.  One person made the above comment and I was thinking (yeah, I know, dangerous).  If at a future time any of us wanted to upgrade the drives in our raid (upgrading size) could you shut down a raid, remove a drive, use a docking station that will duplicate drives and duplicate it, then use a program like EaseUS Partition Master to resize the drive and then place the resized cloned drive into the raid would that work with the program/raid?

Q: Can I change small drives our for larger ones to increase my storage pool's capacity?

• A: Yes.  Drives can be exchanged one at a time to gradually copy all the data onto larger drives, Once all drives have been exchanged the pool's capacity will grow all at once.
  • Example: Lets say we have a pool with 6x10TB drives in RAIDz1, and we swap those out one by one for six 20TB units. When the last 20 TB drive has been installed, and the pool has finished re-silvering (copying data to a drive to re-construct the pool) then the pool's total capacity will jump from ~50TB usable to ~100TB usable!

Hex OS uses the ZFS filesystem which is software raid. It's worth getting to know ZFS, even if you just keep to the "high level" points and topics. Understanding the filesystem, how it handles drive failures, how it re-builds vdev's, why it is RAM hungry will all better enable you to not only understand your system but also know what to do when something goes wrong.

HERE YOU GO.

Good luck!
