我尝试在 Arch Linux 中配置 lvm。但在配置和启动后，我收到此错误：
未指定文件系统类型。
以下都是详细信息。请点击以下每个链接查看相关图片。
步骤1在第一步中我展示了我的分区设置。
第2步在此步骤中，我修改了 grub.config 和 lvm.config 中的 mkinitcpio.config 条目以进行钩子操作。之后，我还使用预设执行了 mkinitcpio -p。
附加 mkinitcpio.conf 文件
# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES=(piix ide_disk reiserfs)
MODULES=(dm_mod)
# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image. This is run last, so it may be used to
# override the actual binaries included by a given hook
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=()
# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way. This is useful for config files.
FILES=""
# HOOKS
# This is the most important setting in this file. The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added. Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
## This setup specifies all modules in the MODULES setting above.
## No raid, lvm2, or encrypted root is needed.
# HOOKS=(base)
#
## This setup will autodetect all modules for your system and should
## work as a sane default
# HOOKS=(base udev autodetect block filesystems)
#
## This setup will generate a 'full' image which supports most systems.
## No autodetection is done.
# HOOKS=(base udev block filesystems)
#
## This setup assembles a pata mdadm array with an encrypted root FS.
## Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
# HOOKS=(base udev block mdadm encrypt filesystems)
#
## This setup loads an lvm2 volume group on a usb device.
# HOOKS=(base udev block lvm2 filesystems)
#
## NOTE: If you have /usr on a separate partition, you MUST include the
# usr, fsck and shutdown hooks.
HOOKS="base udev autodetect modconf block keyboard keymap resume encrypt lvm2 filesystems fsck"
# COMPRESSION
# Use this to compress the initramfs image. By default, gzip compression
# is used. Use 'cat' to create an uncompressed image.
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
#COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"
# COMPRESSION_OPTIONS
# Additional options for the compressor
#COMPRESSION_OPTIONS=()
/etc/default/grub 标志更改为 GRUB_ENABLE_CRYPTODISK=y
GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR='Manjaro'
GRUB_CMDLINE_LINUX_DEFAULT="quiet resume=UUID=471880b5-8b75-49da-9bea-20441bff363e"

#GRUB_DISABLE_LINUX_UUID=true
# Uncomment to disable generation of recovery mode menu entries
GRUB_DISABLE_RECOVERY=true
# Uncomment and set to the desired menu colors. Used by normal and wallpaper
# modes only. Entries specified as foreground/background.
GRUB_COLOR_NORMAL="light-gray/black"
GRUB_COLOR_HIGHLIGHT="green/black"
# Uncomment one of them for the gfx desired, a image background or a gfxtheme

#GRUB_THEME="/path/to/gfxtheme"
# Uncomment to get a beep at GRUB start
#GRUB_INIT_TUNE="480 440 1"
在 lvm.conf 文件中我修改了 Use_lvm_metad=0
步骤3在此屏幕截图中，我收到密码提示。请参阅屏幕截图
步骤4 输入密码后，我得到了 grub 屏幕
步骤5选择菜单选项时出现错误“未指定文件系统的错误”。
答案1
经过一些研发，我终于解决了这个问题。我现在只是在回答这个问题。
该问题是由于根加密分区无法挂载，因为下面的行不存在
GRUB_CMDLINE_LINUX="cryptdevice=UUID=47d9afe4-937f-4a11-b0c2-dda04c0ab14f:cryptlvm"
我附上了我的所有配置。这对其他人很有用
