So, I made a mistake and installed FreeNAS on the HDD on the server (this is a home share). I made a USB bootable media and installed it on the server.
After reading docs I realized I needed to install it on a USB media. I did that successfully, and I boot my computer with FreeNAS USB storage, 16GB.
Now when I go to GUI, it doesn't show the hard disk I have on the machine, all it shows is da0 -15 GB.
This is what I see from gpart show:
[root@freenas ~]# gpart show
=> 34 30277565 da0 GPT (14G)
34 8190 - free - (4M)
8224 1024 1 bios-boot (512k)
9248 30268344 2 freebsd-zfs (14G)
30277592 7 - free - (3.5k)
=> 34 625142381 ada0 GPT (298G)
34 1024 1 bios-boot (512k)
1058 6 - free - (3.0k)
1064 625141344 2 freebsd-zfs (298G)
625142408 7 3 freebsd-ufs (3.5k)
How to solve this problem. Thanks.
I solved it:
sysctl kern.geom.debugflags=0x10
dd if=/dev/zero of=/dev/ada4 bs=512 count=1 && dd if=/dev/zero of=/dev/ada5 bs=512 count=1
Forgot to reboot afterwards, thats why it didn't show in disks, now all ok.
