Unknon drive after installing TrueNAS

Hello.

I just have installed TrueNAS on my Aoostar WTR Max onto an SATA SSD.

After installing, I can see two drives, although the only drive installed in the system is the above mentioned SATA SSD (sdb).

Is this a normal behavior?

truenas_admin@truenas[~]$ lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 1 0B 0 disk
sdb 8:16 0 232.9G 0 disk
├─sdb1 8:17 0 1M 0 part
├─sdb2 8:18 0 512M 0 part
└─sdb3 8:19 0 232.4G 0 part

Thanks.

BR

Search the forums for your model. I think it is normal ‘issue’ with how that model sees the boot device or how it is installed.
