Hi,

i have a SLES 12 SP3 box, which boots in an emergency shell. It seems i have a problem with dracut and also with systemd. To both i'm pretty new so sorry if i ask
silly stuff.
I just can provide you with screenshots because i'm connected to the host with an HP ILO RC, which does not allow copy/paste.
My / is mounted in a snapshot (/dev/sda1): https://hmgubox.helmholtz-muenchen.de/f/21b095deee9143bca13b/
>From where does that come ? I didn't find any configuration saying "take the snapshot !". Nothing in /etc/dracut.conf and /etc/dracut.conf.d.
Au contraire, my dracut.conf says explicitly to not use a snapshot: https://hmgubox.helmholtz-muenchen.de/f/8ac6460ee6e24389b090/
Also /proc/cmdline says after the boot that it would use the "real" volume, not a snapshot: https://hmgubox.helmholtz-muenchen.de/f/b42304ceabf64f50bb14/
dracut --print-cmdline says to use the snapshot: https://hmgubox.helmholtz-muenchen.de/f/112f657bd05b42468600/
I configured my initramfs again: https://hmgubox.helmholtz-muenchen.de/f/0332cc0dab324c32addf/
That's the result: https://hmgubox.helmholtz-muenchen.de/f/dfaf1e15cba647deb420/ . I see several root fs. From where does the snapshot comes ?

Thanks.


Bernd
