Installing TrueNas Scale: "Can not find sda3 Not a block device"

TrueNAS General
,
5

Hello,

I had the similar issue recently with being unable to install on a bios system with 24.04.

The error was:
lsblk: CANT_FIND_sda3_OR_sdap3: not a block device

This is what I did(based on this pull request):

  1. In the installer, select “2. Shell”.
  2. In the shell, type in vi /usr/sbin/truenas-install
  3. In vi, type /SUCCESS
  4. Look in the next few for a line with return 0 (maybe 15 lines)
  5. Move the cursor on the line before (should be empty)
  6. Type in a to append text
  7. Type sleep 20
  8. Press the escape key.
  9. Type in :wq followed with the enter key
  10. You should be back in the shell
  11. Press CTRL + d to return to the installer.
  12. Choose Install/Upgrade

This will cause the script to pause for 20 seconds for both drives(if a mirroir install is selected) and should be enough for the partition to show up. If not increase the sleeping time.

For reference, here’s the function where the sleep cmd should be inserted(near the end)

wait_on_partitions()
{
    if [ "$#" -lt 2 ]; then
        echo "FATAL: A disk and at least one partition number must be given" > /dev/tty
        return 1
    elif [ ! -b "/dev/${1}" ]; then
	# we assume the block special device exists
	echo "FATAL: Disk device (/dev/${1}) not found" > /dev/tty
	return 1
    fi

    local _disk="$1"
    shift
    local _sleeptime=1
    local _maxwait=30
    local _slepttime
    local _parts="$*"
    local _part _slepttime
    for _part in ${_parts}; do
        _slepttime=0
        while [ ${_slepttime} -lt ${_maxwait} ]; do
	    if [ -b "/dev/${_disk}${_part}" ]; then
                echo "SUCCESS: Found /dev/${_disk}${_part}" > /dev/tty
                break
            elif [ -b "/dev/${_disk}p${_part}" ]; then
                echo "SUCCESS: Found /dev/${_disk}p${_part}" > /dev/tty
                break
            else
                sleep ${_sleeptime}
		_slepttime=$(expr $_slepttime + 1)
                echo "Slept ${_slepttime} seconds waiting on disk (${_disk}) partition number: ${_part}" > /dev/tty
		if [ ${_slepttime} -eq ${_maxwait} ]; then
		    echo "FATAL: Could not find /dev/${_disk}${_part} or /dev/${_disk}p${_part}" > /dev/tty
		    return 1
		fi
	    fi
	done
    done

    sleep 20 # This is where the sleep cmd should be inserted
    return 0
}
