Hi there, im a truenas noob. Im playing arround with truenas, and truenas vant find all my drives. I have 12 discs in my nas.
1 nvme 500 gb with win 11 os,
1 ssd drive 128 gb with trunenas os,
3 hdd 4 tb drives,
4 hdd 500 gb drives
3 hdd 500 gb (2,5”) drives.

3 of the disk will not show up in gui. Not sure if its the 3,5” or 2,5 ”. Windows shows all the drives. All 500 gb drives are formatted and ready to use.

Why wont they show up in truenas???

Thank you

Hardware specs? Like how drives connected? to HBA? to motherboard? via USB?

They are connected trough raidcontroller, it works like a sata controller at the moment. The raid controller has 8 connections, and truenas finds 5 of them. I’ve changed 3 of the disc that truenas did not find, but it did not help. The cables does work, because windows find all the discs.

I have asus b450 prime motherboard.
4 of the discs are connected trough motherboard.

Yeah, that is 100% not okay and not supported.

What kind of raid controller? Is it flashed properly?

Because both FreeBSD and Linux try REALLY HARD to make broken hardware work.

But you do not want to use BROKEN HARDWARE with ZFS. You will quite likely end up with broken data.

So maybe its better to use original sata controller? PCIe card with plenty of sata connections?

And what is HBA?

Host Bus Adapter, a term we mostly use to describe non-RAID SAS (SCSI) controllers, but that is not infrequently used to describe any SCSI controller or even any (S)ATA or SCSI/SAS controller. So named because it adapts the disk interface to the host bus.

Probably not, unless it's designed for server use with a nice PCIe x8 slot and a quality chipset.

And what is HBA?

There's a link above that you were given that describes this in great detail.

Okay, i have a motherboard with 4 sata connections. So if truenas dont like raidcontroller or satacontrollers.. so then i only get a few discs i my nas. How can people get plenty of discs in their truenas?

It's not TrueNAS that doesn't like RAID controllers. It's ZFS. Please see link you've already been pointed at.

As for SATA controllers, they're typically made for Windows and many of them are dodgy. You can get a bit more info here:


How can people get plenty of discs in their truenas?

The conventional way: you use SAS gear, which conveniently is largely SATA compatible. You can get 20PB (that's 20 petabytes, or 20000 terabytes) on a single system; remember that it's pretty easy to get 90 HDD's into a 4U space. With 20TB HDD's that's nearly 2PB per shelf, and if you have a 48U rack, you can cram 11 shelves plus a head in there for 19.8PB (990 hard drives). Big machine, but all attached to one machine. Please check out the following link.

Find hardware that compatible with truenas/zfs/freebsd/linux (example LSI HBA or motherboard with more than 4 SATA connections (they do exists))
