Fresh install, Encrypted raidz, 5 disks. Boot fails at error:


zfs i/o error - all block copies unavailable


What could cause this? I've reinstalled several times and same fault every time. FreeBSD has worked before with this same computer. Booted up with Ubuntu-live and disks seems to be OK.

Hmm. Just a hunch, but have you tried wiping the install disk completely before installing - using dd for instance? I've found that if I haven't done this, sometimes information from previously used RAID controllers or ZFS related boot information can be left on the disk making subsequent installs have weird problems.

I’d focus on the “can’t find /boot/zfsloader” bit before going much farther.
I think that's just a consequence of the I/O errors.

I'd check to see if your keys are correct. If it fails to decrypt the disks ZFS won't be able to read them. Also check the disks themselves for bad sectors, especially with encrypted filesystems those can give you really weird results.

Wiped disk with dd and changed mini-keyboard to normal keyboard and now everything works fine. Thanks to all! :)

I got error when calculatating geli decryption key disk3.

Failed to read pad2 area of primary vdev

Should I be worried? Zpool status says pool is okay, but I made zpool scrub to pool anyway.

And the S.M.A.R.T. data shows nothing that could point at problems?

Maybe the drive itself passed.
But I am not sure the environment is not FAILING_NOW, as shown in the list.

For my part I find the value #190 particularly interesting.
As it is difficult to correctly interpret these smart values into actual temperatures, it's hard to say how warm it is in that computer's drive bay.

But I guess it is safe to assume that it is a bit uncomfortably warm for the drives already. Maybe they want a bit more fresh air?

The temperatures of your disk seem awfully high. When drives get too hot you can get weird random issues.

Not just drives, but all sort of electronics too; especially any type of amplifier circuitry. Then again humans seem to go berserk with too much heat. :eek:
