[SOLVED] system not booting with LVM root and systemd

hi everyone ,

I've update my arch installation and performed the upgrade to systemd , and after that the system is not booting , it brings me to a recovery shell .

the root FS is on LVM , and everything under /dev/mapper is missing .

journalctl -xb -p err show me this error :

lvm services are enabled on systemd , but under /dev/mapper i find only  /dev/mapper/control , all the other files are missing  (list from another install)

 ls -l /dev/mapper/*

Re: [SOLVED] system not booting with LVM root and systemd

lvm services are enabled on systemd

Which?

tried also vgchange -ay from recover shell but still no luck

Did you do vgscan first? What error did you get or did the command just return empty?

Is the lvm2 hook in mkinitcpio.conf? Have you tried regenerating your initramfs?

Re: [SOLVED] system not booting with LVM root and systemd

regenerating the initrams fixed the problem , also if the LVM2 hook was already present in mkinitcpio.conf

thank you very much
