 Posted: Thu May 14, 2020 2:00 pm Post subject: boot failed as systemd's jobs to mount lvm volumes timed out |
 |
|
My gentoo was set up with /, /usr, /var, /home, /opt, /tmp each on a separate LVM volume.
| Code: |
/dev/sda5 /boot ext4 noauto,noatime 1 2
/dev/vg/root / ext4 defaults 0 1
/dev/vg/usr /usr ext4 defaults 0 0
/dev/vg/opt /opt ext4 defaults 0 0
/dev/vg/tmp /tmp tmpfs defaults 0 0
/dev/vg/var /var ext4 defaults 0 0
/dev/vg/cache /var/cache ext4 defaults 0 0
/dev/vg/db /var/db ext4 defaults 0 0
/dev/vg/log /var/log ext4 defaults 0 0
/dev/vg/vartmp /var/tmp tmpfs defaults 0 0
/dev/vg/home /home ext4 defaults 0 2
|
kernel was | Code: | | sys-kernel/gentoo-sources-5.4.38:5.4.38 |
, compiled with | Code: | | sys-kernel/genkernel-4.0.7-r1 |
. The profile was | Code: | | default/linux/amd64/17.1/desktop/gnome/systemd (stable) |
. I used | Code: | | sys-boot/grub-2.04-r1 |
to set up booting.
It failed to boot. It tried for 1 min 30s of mounting /var and those directories under /var, /opt, /home, saying "A start job is running for /dev/vg/var".
showed something like this
| Code: |
-- Subject: A start job for unit dev-vg-var.device has failed
-- Defined-By: systemd
-- Support: https://gentoo.org/support/
--
-- A start job for unit dev-vg-var.device has finished with a failure.
--
-- The job identifier is 21 and the job result is timeout.
May 14 21:53:15 localhost systemd[1]: Dependency failed for /var.
-- Subject: A start job for unit var.mount has failed
-- Defined-By: systemd
-- Support: https://gentoo.org/support/
--
-- A start job for unit var.mount has finished with a failure.

Could somebody help?
The strange thing was that if I used genkernel-next to generate the kernel, the system would boot. But the kernel generated by genkernel failed at mounting the lvm volumes.
Thank you for helping! |

Hi,
Do you have an initramfs?
You need an initramfs to boot if your root is on lvm.
Also have you enabled lvm?
| Code: |
systemctl enable lvm2-monitor.service

Yes, | Code: | | lvm2-monitor.service |
was enabled.
initramfs was also there. I didn't change anything that genkernel or genkernel-next generated. |

Or even better install dracut and use it to create your initramfs
| Code: |
emerge -av sys-kernel/dracut
dracut /boot/initramfs-<kernel-version>.img <kernel-version> #### IOR
dracut /boot/initramfs-$(uname -r).img $(uname -r) #### OR
dracut (--force)
grub-mkconfig -o /boot/grub/grub.cfg
|
It has been a long time since
| Code: |
genkernel --lvm --install initramfs
|
produced a good working initramfs for me(you also need the "dolvm" flag in linux command line in /etc/default/grub).
So i ditched genkernel in favor of dracut instead
