mkfs.vfat: 无法打开 {partition}: 没有这样的文件或目录命令成功，但抛出此错误并阻止脚本的其余部分

如何解决mkfs.vfat: 无法打开 {partition}: 没有这样的文件或目录命令成功，但抛出此错误并阻止脚本的其余部分

更新：我得到了这个工作，但仍然不是 100% 确定为什么。我已将完整且一致的工作脚本附加到末尾以供参考。

我正在尝试使用 sgdisk 和 mkfs.vfat 编写一系列磁盘分区命令的脚本。我使用 Live USB (NixOS 21pre) 工作，有一个空白的 1TB M.2 SSD，正在创建一个 1GB EFI 启动分区和一个 999GB ZFS 分区。

一切正常，直到我尝试使用 mkfs.vfat 在 EFI 分区上创建 fat32 文件系统，我在标题中收到错误。

然而，奇怪的是，mkfs.vfat 命令成功了，但无论如何都会抛出该错误并阻止脚本的其余部分。知道为什么要这样做以及如何解决吗？

从未格式化的 1TB M.2 SSD 开始：

$  sudo parted /dev/disk/by-id/wwn-0x5001b448b94488f8 print
Error: /dev/sda: unrecognised disk label
Model: ATA WDC WDS100T2B0B- (scsi)                                        
disk /dev/sda: 1000GB
Sector size (logical/physical): 512B/512B
Partition Table: unkNown
disk Flags: 

脚本：

$ ls

$  cat partition.sh
#!/usr/bin/env bash
#make gpt partition table and boot & rpool partitions for ZFS on 1TB M.2 SSD

#error handling on
set -e

#wipe the disk with -Z,then create two partitions,a 1GB (945GiB) EFI boot partition,and a ZFS root partition consisting of the rest of the drive,then print the results
disK=/dev/disk/by-id/wwn-0x5001b448b94488f8
sgdisk -Z $disK
sgdisk -n 1:0:+954M -t 1:EF00 -c 1:efi $disK
sgdisk -n 2:0:0 -t 2:BF01 -c 2:zroot $disK
sgdisk -p /dev/sda

#make a fat32 filesystem on the EFI partition,then mount it
#mkfs.vfat -F 32 ${disK}-part1 (troubleshooting with hardcoded version below)
mkfs.vfat -F 32 /dev/disk/by-id/wwn-0x5001b448b94488f8-part1
mkdir -p /mnt/boot
mount ${disK}-part1 /mnt/boot

结果（一切正常，直到 mkfs.vfat 抛出错误并阻止脚本的其余部分）：

$  sudo sh partition.sh

验证分区和 fat32 创建命令有效：

$ sudo parted /dev/disk/by-id/wwn-0x5001b448b94488f8 print
Model: ATA WDC WDS100T2B0B- (scsi)
disk /dev/sda: 1000GB

 2      1001MB  1000GB  999GB                zroot

Fwiw，同样的命令在命令行上工作没有错误：

$  sudo mkfs.vfat -F 32 /dev/disk/by-id/wwn-0x5001b448b94488f8-part1
mkfs.fat 4.1 (2017-01-24)

成功。但是为什么命令行没有错误，脚本却有错误？

更新：完全一致的工作脚本：

#!/usr/bin/env bash
#make UEFI (GPT) partition table and two partitions (fat32 boot and ZFS rpool) on 1TB M.2 SSD

#error handling on
set -e

#vars
disK=/dev/disk/by-id/wwn-0x5001b448b94488f8
POOL='rpool'

#0. if /mnt/boot is mounted,umount it; if any NixOS filesystems are mounted,unmount them
if mount -l | grep -q '/mnt/boot'; then
  umount -f /mnt/boot
fi
if mount -l | grep -q '/mnt/nix'; then
  umount -fR /mnt
fi

#1. if a zfs pool exists,delete it
if zpool list | grep -q $POOL; then
  zfs unmount -a
  zpool export $POOL
  zpool destroy -f $POOL
fi

#2. wipe the disk
sgdisk -Z $disK
wipefs -a $disK

#3. create two partitions,then print the results
sgdisk -n 1:0:+954M -t 1:EF00 -c 1:efiboot $disK
sgdisk -n 2:0:0 -t 2:BF01 -c 2:zfsroot $disK
sgdisk -p /dev/sda

#4. notify the OS of partition updates,and print partition info
partprobe
parted ${disK} print

#5. make a fat32 filesystem on the EFI boot partition
mkfs.vfat -F 32 ${disK}-part1

#6. notify the OS of partition updates,and print new partition info
partprobe
parted ${disK} print

#mount the partitions in nixos-zfs-pool-dataset-create.sh script. Make sure to first mount the ZFS root dataset on /mnt before mounting and subdirectories of /mnt.
