Root mount error when booting from USB

[biozinc]

I've just dd'd 8.0.2 amd64 image to a flash drive and booted up FreeNAS. I'm getting a "ROOT MOUNT ERROR" on boot:

Code:

The startup sequence stoops asking for input. If I type in ifs:/dev/ufs/FreeNASs1a, it completes, and starts up fine. However, this means the box doesn't boot properly without manual input. What am I doing wrong here?

Try writing the image to the USB drive again - my initial reaction is that it's corrupt. Which image did you use, "Full Install"? Check the sha256 to make sure what you downloaded is correct.

 

[biozinc]

So an update:

- I wrote the image again to a different flashdrive, but using Physdiskwrite this time. The flash drive was a Kingston DataTraveler 8Gb. The exact same thing occured.
- Checked the SHA256 hash of the Full_Install.xz. It's correct

and

- In the meanwhile, added another 2 disks to the box, and now it boots correctly! I still get this bit of output:

Code:

Oct 16 00:13:06 morpork kernel: GEOM: da0s1: geometry does not match label (16h,63s != 255h,63s).
Oct 16 00:13:06 morpork kernel: Trying to mount root from ufs:/dev/ufs/FreeNASs1a

I'm worried that the problem is not solved and may come back. Any ideas?

Those errors are 'normal', they happen to everyone during every boot, don't worry.

It's interesting how the problem fixed itself after adding the disks. Hopefully this will be a clue to help the developers fix the problem.

I solve this disabling USB 2.0 support in BIOS.

I am having the same issue. Strange though as it seems to have persisted across two completely separate unrelated setups (mobo, drives, usb stick, and all). First thought was a bad install so i tried again at least three times on each system with no luck. Swapped flash drives in the event one was bad still with no luck. Thought i had a bad cd so i tried a several fresh burns from multiple fresh downloads (8.0.2 32bit version, and the current night lightly also 32bit). Tried the advise with disabling usb 2.0 in bios also with no change.

 

[d_shev]

Try to change other parameters in BIOS (In the first place - related to USB)

I had almost the same error shown in the OP, a "ROOT MOUNT ERROR". In my case I was booting off a USB stick in a USB 3.0 port. What I discovered was that USB 3.0, aka XHCI, is disabled by default. Having re-enabled it by using info in the following posts, I've been able to get FreeNAS booting:
