Hello again Ubuntu users. My networking problem is solved by creating a 70-persistent-net.rules file in /etc/udev/conf.d/. I still experiance the problem with the software raid1. When i remove one of the disks it does not work out. What I have done is to add "BOOT_DEGRADED=true" in /etc/mdadm/mdadm.conf.

WHERE did you backup to? You may have backed up to a boot drive(maybe sda, and overwritten most, if not all of /boot. Check all HDDs on another computer.

Thank you for reminding me to finish this ! Indeed, after looking at the lines, I noticed that: slot:0 was the problem. Assuming it was bad memory, I took it out (Slots are allocated by your motherboard, or at least in mine, slot zero was slot 1 of the mother board) Thus I took it out, tested for 48 hours, and no errors appeared. Sent the RAM to ...

Still tracking this issue? It seems like you have a bad memory module, the machine pauses just waiting for the hardware to correct this error by itself. You may need to try to remove or replace the memory at your first CPU, second channel and first slot.

Just confirming that the BOOT_DEGRADED option is still supported in 14.04, and is still required if you want your server to boot automatically when a disk fails. Source: anecdotal evidence. Just had a disk fail, and the server would drop to a initramfs shell, where I had to manually --force assemble the array. Executing echo 'BOOT_DEGRADED=true' > ...

Ok, looks like I just didn't understand how a RAID 5 works. I had always selected 3+1 without really knowing about the Hot Spare mechanism in RAID 5, which then always resulted in 3 TB x ((3 - 1) - 1) = 6 TB total space https://en.wikipedia.org/wiki/Hot_spare The missing dev/md0 was due to a falsely generated mdadm.conf Cheers

Generally that error indicates that a fatal machine check exception occurred and a timeout occurred while waiting for all the CPUs to become synchronized. While it is hard to say what kind of machine check exception (MCE) occurred from this error message, normally it indicates some fatal hardware error (for example memory <-> CPU or mother board ...

AHCI is the standard interface for SATA controllers. Other options usually include IDE mode, where the controller pretends to be an old IDE controller for compatibility with older operating systems, and RAID, which means fake raid support. Fake raid is actually just an AHCI controller that has bios code and windows drivers to implement raid in software. ...

I can't tel you what is best for you but i will tel you what i did on our internal servers. I always installed Ubuntu or Debian servers on Linux software raid. I already had to recover a broken drive and that was realy easy to do. also the system would just boot with only one drive active. Just hotswap and add it to the lvm volume againe. What i would not ...

For reference, I ended up failing the 2nd disk, formatting and reinstalling with an lvm partition. I stopped the array, and retrieved data from the ext4 partition (not the raid device). Then I migrated the content to the lvm partition, formatted the 1st disk, and extending the lvm. There was probably an easier way to go (migrating the OS partition for ...
