 Posted: Tue Sep 29, 2020 10:19 am Post subject: Unable to mount VG after kernel upgrade during boot |
 |
|
Hello fellas. I am using Grub2, generating new kernel 5.4.60 and initramfs with genkernel.
If i am booting to new kernel, my VG are not mounted during boot (not existing device).
However, when i boot to old kernel 4.14.65, everything work like a charm.
I am generating new kernel with command:
| Code: |
genkernel --lvm --mdadm --no-clean --no-mrproper --menuconfig all
|
And grub has both mdadm and lvm module enabled:
| Code: |
GRUB_CMDLINE_LINUX_DEFAULT="domdadm dolvm"
|
The VGs are running on MD device (RAID 1 - mirror)
| Code: |
#cat /proc/mdstat:
Personalities : [raid6] [raid5] [raid4] [raid0] [raid1] [raid10] [linear] [multipath]
md127 : active raid1 sda4[0] sdb4[1]
2927772096 blocks super 1.2 [2/2] [UU]
bitmap: 1/22 pages [4KB], 65536KB chunk
#pvscan
PV /dev/md127 VG vg01 lvm2 [<2.73 TiB / <720.14 GiB free]
Total: 1 [<2.73 TiB] / in use: 1 [<2.73 TiB] / in no VG: 0 [0 ]
#lvscan:
ACTIVE '/dev/vg01/tmp' [2.00 GiB] inherit
ACTIVE '/dev/vg01/var' [10.00 GiB] inherit
ACTIVE '/dev/vg01/home' [10.00 GiB] inherit
ACTIVE '/dev/vg01/root' [50.00 GiB] inherit
ACTIVE '/dev/vg01/data' [1.95 TiB] inherit
|
Anyone has an idea what would be the issue here? I am really going crazy of the issue.
MD and LVM support is enabled in new kernel. This is for sure.
Help appreaciated. Thank you. |

Hi
You can not mount a vg.
You can mount an lv.
Can you please post your "fstab" and your /var/log/dmesg and your /etc/default/grub
Also did you use the same .config file to compile the new kernel also?

Hello alamahant.
Sure you right only lv is mountable. My mistake. Nevertheless, the issue still persist 
I have slightly different .config for old and brand new kernel.
Here is my fstab (a part not commented out):
| Code: | /dev/vg01/root / ext4 defaults 1 1
/dev/sda2 /boot/efi vfat noauto,noatime 0 2
/dev/vg01/home /home ext4 defaults 0 0
/dev/vg01/tmp /tmp ext4 defaults 0 0
/dev/vg01/var /var ext4 defaults 0 0
/dev/vg01/data /data ext4 defaults 0 0
/dev/sda3 swap swap defaults 0 0
/dev/sdb3 swap swap defaults 0 0
/dev/sdc1 /mnt/sdc1 ext3 defaults 0 0
|
Here is dmesg from new kernel (a snippet, i am not able to paste whole dmesg, finding a way how to attach a file here):

Looking at rc. log i discovered, during sytem boot, lvm components are not loaded during "rc boot" but in later stage - in "rc default".
I am going to check if moving lvm to earlier boot stage will not help.
| Code: |
#rc-update
apache2 | default
binfmt | boot
bootmisc | boot
cgroups | sysinit
devfs | sysinit
dhcpd | default
dmesg | sysinit

And surprisingly YES - this helps completely. Issue is resolved.
Anyway it is not clear to me, why old kernel has no complains, but with new one it won`t work with old rc-update settings.
@alamahant, do you have a clue? |

I have lmv on boot and lvmetad on default.
I dont know...
The old kernel was lucky I guess.....

p3k,
is correct.
Its localmount that reads /etc/fstab' so
starting lvm after boot the boot runlevel is complete is a bit late for localmount.
However, /etc/init.d/localmount says
| Code: | description="Mounts disks and swap according to /etc/fstab."
depend()
{
need fsck
use lvm modules mtab
after lvm modules
keyword -jail -prefix -systemd-nspawn -vserver -lxc |
}
so you should be OK now.
