Hi, i’m getting desperate. I installed a fresh SLES 12 SP3, but it does not boot cleanly. Systemd is always hanging here: [https://hmgubox.helmholtz-muenchen.de/f/df2c63af75d7458cac0e/?dl=1](https://hmgubox.helmholtz-muenchen.de/f/df2c63af75d7458cac0e/?dl=1) . Unfortunately i didn’t find a way to copy/paste from the remote console, neither Java nor .NET. So i have to provide you with screenshots :-)) IMHO it seems that the device nodes are not present. After 90s systemd continues and finishes in an emergency shell. But then the device nodes are visible ! Under /dev/disk/by-uuid and directly unter /dev/sda\* I followed [https://www.suse.com/de-de/support/kb/doc/?id=7018491](https://www.suse.com/de-de/support/kb/doc/?id=7018491) and extended the timeout to 200s, but that didn’t help. When i start top i just see 0KiB total for swap. My root volume is BTRFS, but just the root volume is mounted, not the subvolumes like /opt, /usr/local … I changed the entries in fstab from UUID to /dev/sda\*, but that doesn’t help. Swap and /boot is still missing, and all BTRFS subvolumes. I can /dev/sda3 to /boot manually. But trying to mount the subvolumes via mount -a does not succeed. But without any error message. What also is strange is where / is mounted: [https://hmgubox.helmholtz-muenchen.de/f/21b095deee9143bca13b/?dl=1](https://hmgubox.helmholtz-muenchen.de/f/21b095deee9143bca13b/?dl=1) Journalctl -xb says the jobs are timed out. I’m thankful for each help. Bernd ---

Hi, i’m still struggling. What i’m very surprised about is my strange mountpoint for my root /: [https://hmgubox.helmholtz-muenchen.de/f/21b095deee9143bca13b/?dl=1](https://hmgubox.helmholtz-muenchen.de/f/21b095deee9143bca13b/?dl=1). Is that the problem or is that a result of the problem? /proc/cmdline does not show anything with snapshots, there everything seems to be right. The devicce files are available now like sda2 or sda3, i can mount sda3 manually and swapon sda2. Is it correct that i don’t find the corresponding device units in /usr/lib/systemd/system ? IMHO they are created on the fly by systemd-fstab-generator, but afterwards deleted ? And … does anyone know how to copy/paste in the ILO RC ? It’s pretty poor to create snapshots. Bernd ---

Hi So can you check /etc/fstab and /etc/default/grub for the UUID entries The mount -a command won’t work for btrfs subvolumes you need to mount for example; ```auto mount -t btrfs -o subvol=new_subvol /dev/sda2 /mnt/new_subvol mount -t btrfs -o subvol=snapshot_of_root /dev/sda2 /mnt/snap ``` You can see all the references vi /usr/sbin/blkid command. ---

Hi, Thanks for that information, Malcom. I’m still struggling. This is my first intensive contact with systemd … init was so easy :-)) I still can’t understand why my / is mounted to a snapshot: [https://hmgubox.helmholtz-muenchen.de/f/21b095deee9143bca13b/](https://hmgubox.helmholtz-muenchen.de/f/21b095deee9143bca13b/) I tried to configure my initrd with a “normal” root:[https://hmgubox.helmholtz-muenchen.de/f/0332cc0dab324c32addf/](https://hmgubox.helmholtz-muenchen.de/f/0332cc0dab324c32addf/) But the results of dracut showed also the root with the snapshot, beneath my configured root: [https://hmgubox.helmholtz-muenchen.de/f/dfaf1e15cba647deb420/](https://hmgubox.helmholtz-muenchen.de/f/dfaf1e15cba647deb420/) And also journalctl confirms that: [https://hmgubox.helmholtz-muenchen.de/f/c129fc90ac934c8aaf81/](https://hmgubox.helmholtz-muenchen.de/f/c129fc90ac934c8aaf81/) From where does it come ? It must be configured somewhere. Does anyone know where ? I also followed [https://bbs.archlinux.org/viewtopic.php?id=192991](https://bbs.archlinux.org/viewtopic.php?id=192991) , but the device for my BTRFS volume timed out again, although it’s visible under /dev/disk/by-uuid !?!

Hi So it must have booted into the snapshot…? At GRUB advanced option do you see this snapshot? On my SLED 12 SP3 I see; ```auto dracut --print-cmdline resume=UUID=852981f9-f3a8-45ee-a793-eac221e8521a root=UUID=6f38513f-8a76-41ee-b9ff-44de1d8b8701 rootfstype=btrfs rootflags=rw,relatime,ssd,space_cache,subvolid=257,subvol=/@,subvol=@ ``` The other place to look is /etc/default/grub, if you make changes remember to run; ```auto grub2-mkconfig -o /boot/grub2/grub.cfg ``` Maybe there was an error running this during install? ---
