My computer starts in emergency mode. My processor is AMD Rysen Threadripper 1950x. I am on Ubuntu 16.4 LTS. These error lines keep printing on the terminal:
[ 3276.313138] pcieport 0000:00:01.1 PCI Bus Error: severity:Corrected, type=Data Link Layer, id=0009(Receiver ID)
[ 3276.313768] pcieport 0000:00:01.1 device [1022:1453] error xtatu/mask=00000080/00006000
[ 3276.314401] pcieport 0000:00:01.1 [ 7] Bad DLLP
And I cannot find the files within my home directory. That is, I can go to my home directory, cd /home/joe, and there are directories within, but everything is empty! I have my operating system on /dev/mven0n1p1. But my home is on (I believe sda, sdb, sdc, and sdd). I have those 4 drives in Raid 10. If remember them to be collectively named md1. I tried
mount /dev/md1 /mnt
mount special device /dev/md1 does not exist
Backstory. My computer died some months ago - it started crashing intermittently, then crashed every five minutes. I finally analyses the problem being a faulty water-based cpu cooler. I just replaced that and my temperature is now under control. However, I am stuck in emergency mode whenever I boot.
journalctl -xb and fdisk printouts are here: https://gist.github.com/molnarjoe/a721545a7a8ed22daf550c2bdc24c873
Edit: I found this page with a hint: https://ubuntuforums.org/showthread.php?t=2400299 I believe my disk name has changed!!! I am mounting a disk on boot which now has a different UID. But I don't know which one it is. I am including the blkid and fstab printouts at https://gist.github.com/molnarjoe/09b6339e2dbf25aa387aa68680936a5b
The UID in question is for the /home directory.
Problem turned out to be something different. I have 4 X 1TB drives in Raid 10. One of them remained unplugged after putting my box back together after diagnosis. I found the problem by comparing blkid vs. fstab outputs. My UID for a disk on fstab to mount was not on the blkid. And there were only 3 of the 4 disks on blkid. I poked around the cables until I found the loose one. Now I’m good. Working again. Strange symptom for an even stranger problem. Maybe someone can use this lesson.
