i build a small Server with Ubuntu 14.04 for Samba, I has one SSD Drive (the ubuntu installation is on it) and 2 3TB SATA Disk, the sata disk are combined to a Raid 1 with mdadm.
Now sometimes (no everytime, i think it's maybe related to a dirty shutdown) the system hangs at the boot process:
incrementally starting raid arrays mdadm: Create user root not found mdadm: create group disk not found incrementally started raid arrays
these 4 lines keep repeating. It's really strange cause the boot volume (the ssd) isn't configured as raid and this should not affect it?
Important edit: if i press ctrl + alt + del , the server reboots and starts up normaly,
if i look at the raid dev
mdadm --detail /dev/md0
after the boot, everything looks good.
I'm not a linux pro and didn't find anything on the internet related to these errors, so now i'M a littel stuck, maybe somebody has a clue what the problem could be or some advanced troubleshooting advises (log files etc)?
thanks for reading regards Stefan
