/dev/centos/root and so on doesnt mount


Hello there. I have fresh installation of Centos 7 minimal. Installation goes perfectly. I do some cosmetic stuff like allowing ssh for root, creating team from eth adapters. Then i do reboot and it boots to dracut with /dev/centos/root and swap not found. But if then i do hard poweroff, it boots normaly. And if i input reboot command then it boots to dracut.

The server has Adaptec 6805E controller (just bought) which is in optimal state. System runs on 2x SAS drives in RAID 1.

This is pretty strange issue, any ideas?

Sounds like whatever device holds the root filesystem and swap isn't coming up on a reboot. I have a laptop that does something similar, it refuses to detect the SSD on a reboot and I get the "no bootable medium found" message. I have to cold boot it every time.

I would think it would have to be a problem with either the BIOS or the firmware on the drive. I can't see the operating system being able to affect this in any way.

Which drive holds the root filesystem and swap?

System is being held on Raid 1 volume made of 2 SAS drives. I also forgot to mention that i had installation on this server before and it was totally ok. The only difference is the raid controller, this issue appeared only with new controller. Where should i look in options?

Have you updated your raid card to the latest firmware? How about the BIOS?

I have adaptec cards in a lot of systems and have never seen that issue. I even have a 6405 on my home server running CentOS 6.

You could try contacting Adaptec support. Their support line is one of the better ones out there.

Do you see any difference in the adaptec bios messages when you cold boot vs reboot?

This is the response i got from Adaptec support:

Quote:
Then you should verify that the dracut boot has the aac module and points to the 6805E for the root file system. The only think different from a cold boot is the information regarding the boot process in dracut.
But i dont really understand what i need to do... Can you guys help me with that?
