Boot on SSD ras.pi3

Support
1

Hello
I want to boot from my sdcard and use my system on an ssd plug in usb port

on the sdcard I add a /boot/cmdline.txt
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/sda3 rootfstype=btrfs elevator=deadline fsck.repair=yes rootwait

on the ssd /etc/fstab
/dev/sda3 / noatime,noerror 0 1

Problem Description
/dev/mmcblk0p1 /media/root/0F47-1CA3 vfat 23%13.2 Mio / 59.9 io
/dev/mmcblk0p2 /media/root/819dc0b2-b94c-49cf-8ab9-28fd79ac2c6 ext2 48%55.4 Mio / 124.0 Mio
/dev/mmcblk0p3 / /.snapshots btrfs 30% 8.7 Gio / 29.6 Gio

/dev/sda1 /boot/firmware vfat 23% 13.2 Mio / 59.9 Mio
/dev/sda2 /boot ext2 48%55.4 Mio / 124.0 Mio
/dev/sda3 btrfs

The system used is the one from the sdcard and not the ssd one
