ok you`ve right but now after the correct installation with only luks and lvm I`ve the following error device-mapper: reload ioctl failed:No such file or directory Failed to setup dm-crypt key mapping for device /dev/sda2 Check that kernel supports twofish-xts-plain cipher I checked the kernel config and appears correct, the output of lsmod is the following Module Size Used by dm_crypt 20642 1 twofish_generic 16486 0 twofish_avx_x86_64 45424 2 twofish_x86_64_3way 25488 1 twofish_avx_x86_64 twofish_x86_64 12570 2 twofish_avx_x86_64,twofish_x86_64_3way twofish_common 20723 4 twofish_generic,twofish_avx_x86_64,twofish_x86_64_3way,twofish_x86_64 ccm 16515 1 arc4 12390 2 ath9k 111518 0 ath9k_common 12926 1 ath9k ath9k_hw 374655 2 ath9k_common,ath9k ath3k 12437 0 ath 22071 3 ath9k_common,ath9k,ath9k_hw btusb 24725 0 mac80211 421465 1 ath9k bluetooth 258391 3 ath3k,btusb x86_pkg_temp_thermal 12390 0 hid_multitouch 12437 0 coretemp 12390 0 iTCO_wdt 12390 0 crct10dif_pclmul 12479 0 crc32_pclmul 12483 0 cfg80211 320349 3 ath,ath9k,mac80211 crc32c_intel 16568 0 iTCO_vendor_support 12938 1 iTCO_wdt 6lowpan_iphc 16649 1 bluetooth ghash_clmulni_intel 12523 0 microcode 41719 0 joydev 16535 0 serio_raw 12439 0 lpc_ich 20629 0 mei_me 12576 0 mfd_core 12807 1 lpc_ich mei 58244 1 mei_me i2c_i801 16533 0 ideapad_laptop 16575 0 shpchp 29571 0 sparse_keymap 13019 1 ideapad_laptop rfkill 18094 4 cfg80211,ideapad_laptop,bluetooth raid10 37123 0 raid456 57671 0 async_raid6_recov 12621 1 raid456 async_pq 12640 2 raid456,async_raid6_recov async_xor 12573 3 async_pq,raid456,async_raid6_recov async_memcpy 12464 2 raid456,async_raid6_recov async_tx 12840 5 async_pq,raid456,async_xor,async_memcpy,async_raid6_recov raid1 28900 0 raid0 16515 0 multipath 12390 0 linear 12390 0 usb_storage 52365 1 nouveau 793903 1 ttm 66567 1 nouveau i915 586099 2 mxm_wmi 12672 1 nouveau drm_kms_helper 37632 2 i915,nouveau drm 216971 6 ttm,i915,drm_kms_helper,nouveau i2c_algo_bit 12633 2 i915,nouveau i2c_core 28590 6 drm,i915,i2c_i801,drm_kms_helper,i2c_algo_bit,nouveau r8169 49390 0 mii 13085 1 r8169 wmi 13114 2 mxm_wmi,nouveau video 16832 2 i915,nouveau How can I solve this problem

This is my first installation with funtoo. I have used a combination of luks and lvm that is I encrypted the partition /dev/sda2. After I've created three volume root, home and portage and formatted with btrfs. The mount point are respectively: /mnt/funtoo, /mnt/funtoo/home,/mnt/funtoo/usr/portage. The sda1 is vfat efi partition where I installed the grub2 . The kernel is debian-sources. The boot.conf is the following "Funtoo Linux General" { kernel kernel[-v] initrd initramfs[-v] params += crypt_root=/dev/sda2 dolvm real_root=/dev/mapper/vg-root rootfstype=btrfs } The boot-boot-update don't has errors. My question is the following during the boot I have this error: No volume groups found. Block device /dev/mapper/vg-root is not a valid root device. Could not find the root block device in . Where I wrong ?
