Adding new drive

[Cam Hauver-Reeves]

I've got a single 3TB drive in a server, and it's out of space. I'd like to add another drive to it, but I don't want my data split across two different drives in my file system. Basically, I want to expand my "red" drive using the new 3TB drive. (shown in screenshot)

I'm pretty clueless as you can probably tell, so any help is greatly appreciated.

Options are: Replace that single drive with a bigger one. You should build another volume with multiple drives for data safety and copy the data to it. To better help you, the forum requires you to provide your server specs.
Also note that you are using more than the recommended ZFS max and you might experience poor performance.

The above is correct, if you wanted to add another single drive the best option would be to create a second pool but it is not the correct way to do things.

but it is not the correct way to do things.

Could you clarify?

You can simply add another drive.

This will work fine, but then you need to be aware that you already have no redundancy and have now doubled your already high chances of total data loss.

A better solution would be the increase your redundancy and increase space.

Ask us how ;)

Unfortunately it involves at least two more drives.

Here are your options:

1. And another pool with single disk. More capacity.
2. Replace current disk with larger disk. More capacity.
3. Mirror current drive and add more drives. This would give you redundancy and more capacity. Requires 3 more disks.

If you're honest... How genuinely likely is it that something would happen to my server? I'm actually pretty concerned about data loss now. It's nothing crazy important on there, but still wouldn't be fun to lose it.

If you are worried about data loss you need to have a backup. If you want uptime then you need to add redundancy to your pool.

100% likely given time

It's all about backups.
Backup everything and you are safe. Use a cloud, another harddrive, external drives (but not on the freenas server itself,...). you have a lot of options. You should do this as you will drive crazy if somethings happens to your data ;)

I've had three drives fail in the last six months, and have not lost any data, they had 40,000-60,000 hours on them.... I found out via Email

I would buy 4-8 3TB drives add a new pool in RAIDz2 ASAP and get your data to it

I am using a temporary pool in addition to my main pool without problems

Whats the performance like with the pool 96% full?

Have Fun
