I am not an educated computer guy, so please be gentle with me :)

I have a server I use to run plex with sonarr and radarr. I am trying to create a raid array on it. I have 10x 12TB drives and I want to use RAID 5

I am running Ubuntu 22.04.4 LTS and I connect from a laptop using ssh

Hardware specs are as follows MB - Super Micro X11SCH-LN4F CPU - Intel Xeon E-2224 Coffee Lake 3.4 GHz Memory - Micron 16GB 288-Pin VLP ECC Unbuffered DDR4 2666

So first I use this command

sudo umount /dev/sdb?; sudo wipefs --all --force /dev/sdb?; sudo wipefs --all --force /dev/sdb

For drives b-k

Then I

sudo sgdisk -n 1:0:0 /dev/sdb

For Drives b-k

and then I

sudo mdadm --create --verbose /dev/md0 --level=5 --raid-devices=10 /dev/sd[b-k]1

When I run the create command, it works initially but within a minute or two, as its building the array, the computer randomly restarts. The only errors I can see in the logs are ones like these ones ...

EDAC MC0: 1 CE ie31200 CE on unknown memory (csrow:2 channel:1 page:0x0 offset:0x0 grain:1 syndrome:0xf8)

EDAC MC0: 1 CE ie31200 CE on unknown memory (csrow:2 channel:1 page:0x0 offset:0x0 grain:1 syndrome:0x45)

Otherwise to me it looks like it just restarts for no reason. When the computer restarts the array is there, but instead of md0 it's md127, its status is clean, degraded and I can't get it to do anything from there.

Here's the system log right before the crash

  • IME using RAID5 across that many disks is a disaster waiting to happen; consider RAID6 at the very least. And ensure you have somewhere to take regular backups Commented Jul 8, 2024 at 8:07

  • Why have you tagged with memory? If that's what you suspect is the issue have you tested it? Commented Jul 8, 2024 at 8:12
  • I suspect its a memory issue based on my limited knowledge and what I see in the logs. However, I tested the memory recently and it all came back good. I could definitely use RAID 6, I will try to build a RAID 6 array tonight and see what happens Commented Jul 9, 2024 at 17:03
  • If you think it's a memory issue then there's absolutely no point whatsoever trying to build a RAID array. At best it'll fail visibly like it is now. At worst it'll fail invisibly and you won't notice until you find your data is corrupt. Address the memory issue first. Take a look at unix.stackexchange.com/q/83257/100397 for suggestions - including the possibility that the report itself is a bug Commented Jul 9, 2024 at 17:19
