Post the photo? This is a generic message and we need to see more information. Is devid 9 missing? Does the initrd on this system contain? /usr/lib/udev/rules.d/64-btrfs.rules That will wait until all devices are available before attempting to mount. If it's not in the initrd, it won't wait and it's prone to races, and you can often get mount failures because not all devices are ready to be mounted. > > OTOH, 5.10.19 boots without a hinch > $ btrfs fi show / > Label: none uuid: 911600cb-bd76-4299-9445-666382e8ad20 > Total devices 8 FS bytes used 3.28TiB > devid 1 size 899.01GiB used 670.00GiB path /dev/sdb3 > devid 2 size 489.05GiB used 271.00GiB path /dev/sdd > devid 3 size 1.82TiB used 1.58TiB path /dev/sde1 > devid 4 size 931.51GiB used 708.00GiB path /dev/sdf1 > devid 5 size 1.82TiB used 1.58TiB path /dev/sdc1 > devid 7 size 931.51GiB used 675.00GiB path /dev/nvme2n1p1 > devid 8 size 931.51GiB used 680.03GiB path /dev/nvme1n1p1 > devid 9 size 931.51GiB used 678.03GiB path /dev/nvme0n1p1 This seems to be a somewhat risky setup or at least highly performance variable. Any single device that fails will result in boot failure. -- Chris Murphy
