I am having booting issues with Ubuntu on 2 hard drives. I built this rig with Nvidia i6800 motherboard, and 2 HDs, The reason for 2 drives is one is the main and the other is a backup.
Main SATA: ST2000DMOOB-2FR102 Backup SATA: WDC WD20EZAZ-00GGJB0
With 2 memory slots gone bad out of the 4 on that i6800 MB, I decided to change out the motherboard. And I did to a: Intel DQ77MK Quad Core i5 3470 3.2GHz 8GB DDR3 Motherboard CPU RAM Combo - 14381
Now with better hardware Ubuntu on both drives is running great! The problem is booting, both drives hang here:
Jan 4 17:47:39 kernel: [ 4.399682] sd 3: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA Jan 4 17:47:39 kernel: [ 4.439785] sdb: sdb1 Jan 4 17:47:39 kernel: [ 4.448272] sd 3: [sdb] Attached SCSI disk Jan 4 17:47:39 kernel: [ 4.677222] ata6: SATA link down (SStatus 0 SControl 300) Jan 4 17:47:39 kernel: [ 93.650765] raid6: sse2x4 gen() 14885 MB/s Jan 4 17:47:39 kernel: [ 93.714763] raid6: sse2x4 xor() 10192 MB/s Jan 4 17:47:39 kernel: [ 93.770764] raid6: sse2x2 gen() 12508 MB/s
Between , ata6: SATA and raid6, is 1.4 minutes. is there a way to see what happening?
Jan 3 23:02:40 kernel: [ 2.595791] ata6: SATA link down (SStatus 0 SControl 300) Jan 3 23:02:40 kernel: [ 92.398272] EXT4-fs (sda1): mounted filesystem with ordered data mode. Opts: (null)
This time at ata6: SATA and EXT4, 1.5 minutes, I'm very curious what is causing this delay.
I have no idea what the problem is, yet google searching has led me to a lot. There is no floppy disc option in the bios.
Really like to get this fix, it takes some time to boot. Thanks for you help.
Using the command:
nano /etc/fstab Main Boot Drive /etc/fstab # <file system> <mount point> <type> <options> <dump> <pass> # / was on /dev/sda1 during installation UUID=3ba4b7d5-9192-43b6-a2b8-955b8eb4ed7c / ext4 errors=remount-ro 0 1 2nd Boot Drive # <file system> <mount point> <type> <options> <dump> <pass> # / was on /dev/sda1 during installation UUID=3bbd0470-d6a3-48e8-8884-e5b2d28fcd00 / ext4 errors=remount-ro 0 1 /swapfile none swap sw 0 0
I know the errors are setting drives to read only and that's ok, but why is it taking so long to boot?
So it seems there is a mounting problem, like I said, this is over my head, and I'm learning more everyday. A fix for this would be great! I no longer get the ubuntu loading screen, not sure why?
Thanks for the help.

I was planning on using the bios to set which drive to boot from but GRUB jumps in and seems to ruin my plans.
Now if I lose the main drive, I cannot boot from the backup drive, I need to fix that. Hopefully I can! The Ubuntu install on both drives is default from file system to swap to ect... It appears only the main drive boots, there is a boot.log file there but, no info in the boot.log file on the back up drive, just a blank empty file. There are files for the kernel.log and system with info in them on the backup drive.
"No btrfs" with both drives using ext4 I see no need for that system. So I will remove it, since it is not needed.
"No swap partition (this will effect hibernation)", this seems to compensate for lack of memory no problem there, I have 8g of memory was planning on going to 32 if needed.
"GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noresume"
I moded that line already with,
Now i can see the drive booting.
Is that the way I should edit that line in that file? I want to keep seeing the booting on screen.
open(or create) /etc/initramfs-tools/conf.d/resume.conf replace(or add) RESUME=UUID=xxx with RESUME=noneissue
That folder conf.d is empty on both drives. No problem creating a file. How do I find the "UUID" and if there is two, which one should I use?
Thanks for your help....
