I have installed ubuntu 21.10 on my system. I have 2 5tb hdds and one 1tb stick (for OS). I have a 430-8i non-raid controller. When I run df-h, the system only recognizes OS drives and the usb 1tb stick. Do I need to downgrade to ubuntu 20.04 to get the drives loaded?
Here is the situation:
I have a Lenovo ThinkCentre M900 with Linux CentOS 7.
I tried to do a kernel load (kexec -l + kexec -e), and it works fine, with one problem.
As soon as I enter the kexec -e command, the Server starts a long alarm beep which sadly doesn't stop.
Am I doing something wrong ? How to reload the kernel without really rebooting ?
I've a problem of random writing speed on a Lenovo X3650 M5 with ServeRAID M5210.
The server has seven 600GB SAS disks divided into two logical groups: a RAID1 (2 disks) and a RAID10 (4 disks)
The last disk is a global hot spare.
The RAID 10 has 500MB/s in seq. reads and 250 MB/s in seq. writes and it almost double the speed of the RAID 1 array as expected.
The problems rise during 4K write test with a result of less then 1 MB/S for both RAIDs in both writes and reads.
The logical virtual disks properties:
RAID 1:
Write Policy: Write Through
Read Policy: Always Read Ahead
IO Policy: Direct IO
Disk Cache Policy: Unchanged
Background Initialization: Enabled
RAID 10:
Write Policy: Write Through
Read Policy: Always Read Ahead
IO Policy: Direct IO
Disk Cache Policy: Disabled
Background Initialization: Enabled

Anyone has any advice?
Since the beginning of the month, automatic reboot after kernel change takes ... 3 hours.
It is a Lenovo Thinksystem server in a datacenter.
journalctl -b -1 ends with:
juil. 23 03:02:25 host systemd-shutdown[1]: Sending SIGTERM to remaining processes...
juil. 23 03:02:25 host systemd-journald[658]: Journal stopped
and journalctl -b starts with:

I have a GRUB_TIMEOUT=0 so I have no idea of what could be the issue.
Edit:
One weird thing is that lshw used to show the server model:

Edit 2:
It seems to be stuck on that screen for hours:
I'm attempting to mount an .ISO file to a remote server using Intel Manageability Commander on a Lenovo TS440 ThinkServer. I've got the system configured to use Intel AMT, and I've enabled everything in the BIOS following this guide from Lenovo.
I've got the server connected in Remote Desktop and I've been able to have nearly full control of the remote system except when I try to mount an IDE-R device to remotely boot to an .ISO file I have. When I try to mount it the program spits out an error:
"Error Occurred starting IDE-R" Choosing any of the three options, Graceful, On Reset, and Immediate all return the same error. Attempting any of the mount options in any power state also returns the same error. I've also checked various other known good .ISO files such as Ubuntu, MemTest86, and unRAID and get the same error.
Googling this exact phrase worryingly returns exactly zero results from Google.
I've rechecked the Intel Management settings to verify the option for IDE-R is enabled, and I even toggled it off and on in the BIOS just to make sure. I verified that the motherboard, BIOS, Raid Card and AMT firmware is up to date (v9.1.45) but still get this error.
Does anyone have any idea why it's not allowing me to mount an IDE-R device? I'm willing to switch to a different AMT software if there's you can recommend. I'd like to get this working so I don't have to make a dedicated trip across town, unless that's what it's going to take to get this fixed.
