I am creating a new pool (for offsite backup) with 3 - 2TB drives. They are mixed brands and rpms so I expect performance to be poor. The problem I am running into is: The pool’s capacity is on only 50% of what I am expecting. Can someone help me understand/troubleshoot this?

Welcome to the TrueNAS forums!
It almost seems like you have a smaller disk in the RAID-Z1 set. Except one of your screen shots shows 3 x 2TB disks…
Please supply the output of the following commands in CODE tags;
zpool list -v
zpool status
lsblk
This should help determine the problem.
Further, did you setup any ZFS quota, reservations?

Thanks for the response!
I have been trying various things since the original setup.
I tried creating 3 separate pools, one for each drive, to see which drives are causing trouble.
sda: looks fine,
sdk: 50% capacity,
sdl: 50% capacity
So I tried to “Expand Pool”:
sda: sucess, no change,
sdk: immediately faulted,
sdl: didn’t work, I think it was because of the running task on sdk and I didn’t want to wait.
So I deleted the pool with sdl and started a full disk wipe with random zero. I was not able to export sdk since it still had an “expand” job running.
Here are the relevant sections of the commands you asked for:

I now have some more questions.
- How can I cancel jobs? That pool expand job is still running at 0%
- Just yesterday I did a long SMART test on all 3 of these drives and they all came back with “success”. How can I access the results of the smart tests and does success mean “no errors”?
- If the drive has errors like this, does it always mean the drive needs to be replaced or can I assume this error has to do with how it it formatted?
smartctl -a /dev/sda
smartctl -a /dev/sdk
smartctl -a /dev/sdl
Not necessarily.
Start from providing the required outputs, we have to evaluate the situation.
Also, do note that 1.8 TiB ≈ 2 TB.
There is nothing wrong with experimenting with an empty NAS server, but boy what a mess you currently have.
A few things you need to do:
-
Get the exact models of your hard drives and check that that specific model is NOT a SMR technology disk. SMR disks are not useable for redundant vDevs with TrueNAS/ZFS.
-
Your pny-ssd-pool is striped without any redundancy - this is NOT a good idea as if one drive dies you will lose the data on the other drive as well.
-
When you are ready to create your production pools, ask for advice about the best setup for the hardware you have. In general terms, vDevs have to use disks of similar sizes (otherwise the space on bigger drives will be wasted), but you can have multiplke vDevs in a pool. For VMs and Apps you do not want to use RAIDZ, and SSDs are best if your data sizes are not too big. For HDDs, generally it is better to have a single pool, but there are circumstances where you may want to split pools.

Thanks!
- The exact models seem to be included with smart reporting. I will try to find whether they are SMR shortly.
- I understand the risk. Most of the data on the pny-ssd-pool is static and I replicate that pool to the ait2408 pool every night. There is a chance I would lose data but unless I also loose the other backup pool it will at most be a day.
- Yes, I am interested in some input on a good setup. I was not aware that RAIDZ is not good for apps and VMs but it makes sense.
Some explanation of the rest of the mess. I have 3 pools in here.
- ssd storage
- HDD backup
- pcs_backup single drive. This is an offsite backup for someone else who has various other backups. If this fails no data is lost unless other terrible things happen at the same.
The rest of the pools are simply to test the drives in question.
Update:
I have not been able to find whether the Hitachi Ultrastar A7K2000 is SMR or not.
The Seagate Barracuda LP seems to be according to this, if Barracuda is same as Barracuda LP
I have not been able find information on the HITACHI HUS724020ALA640 either
These are drives I had laying around and I thought I would use them for my offsite backup. I am not losing much if these drives aren’t any good.
You’ve listed “sdk” as one of the drives. It has a partition of 1/2 the storage, so if that was used in the pool, that would explain the reduced storage.
To fix, simply wipe “sdk”, either by removing the “sdk1” partition or write zeros to the disk. Then retry creating the 3 x 2TByte RAID-Z1 pool again.

Assuming OP used the GUI, how did this happen?
First thing TrueNAS usually does when you setup a pool is format and partition the disks right?
A bug?
That is correct. Everything was done as shown in the screenshots above. This was a used drive so I am not surprised by the partition but I really expected TrueNAS would keep its word and destroy “all” data on the disk…
Aliens, it has to be the evil Goa’uld! At least that’s my story and I am sticking with it.
Back in reality, that is a very good question. Either the GUI should have said something like “disk already has data” because of the preexisting partition table entry and fail to use it. Or simply prompted the user to over-write it.
How can I stop these jobs? They have been stuck here ever since I tried to export the faulted test2 pool. I can’t either export test1 pool. Do I need to reboot?
I have physically removed the drives in hopes that would help but it does not seem to make a difference.
Guys! it works!!
I went ahead and rebooted to clear out those jobs since I could not find any way to stop them and they were preventing me from removing the one disk from Test1.
Removing the partitions did fix the problem.
Thanks for your help!!
If I have time (haha) I might try to reproduce the issue but currently I am thinking I probably had one of those 2TB disks in with a 1TB disk while I was doing some other testing. I am suspicious that since there was a zfs made partition there already it was not wiped.
As far as smart test go, I don’t really understand how to read them. Can I just trust TrueNAS to tell me when there is a problem with a drive or should I check the smart test results occasionally?
Thanks again for your help!
I think there is a bug somewhere there… there are also active reports at the moment of auto-expand not functioning correctly.
If the partitions are being sized wrong that would certainly explain the above.

You should check. Using this helps greatly.
You want to mainly look out for:

And SMART short or long tests that cannot complete the test.
