 |
|
Hello All, When i wonted to extend /usr lvm volume so i found out that is incorrect mounted. Volume is lvm, but mounted is as dm-8. Same is for root /:
| Code: |
pc-marek1 /etc # df -h | grep dm-5
/dev/dm-5 15G 41M 14G 1% /
pc-marek1 /etc # df -h | grep usr
/dev/dm-8 20G 15G 3.6G 81% /usr
/dev/mapper/system-portage 15G 1.9G 13G 14% /usr/portage
/dev/mapper/system-src 20G 13G 5.8G 69% /usr/src |
I tried investigate issue and in dmesg i found that during booting is some problem with lvm, probably some commands missing(failed to execute >>> No such file or directory):
| Code: | pc-marek1 /etc # dmesg | grep -i lvm

It look like that in vmlinuz-6.12.1-gentoo-x86_64 missing some lvm commnads. After mounting root and usr as dm-X devices are rest of lvm volumes mounted correctly.
kernel I commpile via genkernel:
| Code: | | pc-marek1 /etc # genkernel --oldconfig --lvm --mdadm all |
In /etc/default/grub i have line:
| Code: | | GRUB_CMDLINE_LINUX="dolvm domdadm rootfstype=ext4 pv6.disable=1 mitigations=auto rd.driver.blacklist=nouveau nouveau.modeset=0 nvidia_drm.modeset=1 video=vesafb:off,efifb:on rd.lvm.vg=system" |
I checked "how to" of grub, lvm and genkernel but i didn't find nothing useful. Please help me. |

I tried extract initramfs-6.12.1-gentoo-x86_64.img and there missing commnad/file systemd-run
| Code: | pc-marek1 ~/test # file /boot/initramfs-6.12.1-gentoo-x86_64.img
/boot/initramfs-6.12.1-gentoo-x86_64.img: XZ compressed data, checksum NONE
pc-marek1 ~/test # xzcat /boot/initramfs-6.12.1-gentoo-x86_64.img | cpio -idm
pc-marek1 ~/test # find . | grep systemd-run
pc-marek1 ~/test #
