Correct. I didn't notice that part in the lsblk output. The LV ubuntu-lv already seems to be 928GB, the maximum size of the physical partition. But your filesystem is only 98GB and you can extend...

Correct. I didn't notice that part in the lsblk output. The LV ubuntu-lv already seems to be 928GB, the maximum size of the physical partition. But your filesystem is only 98GB and you can extend...
When using LVM basically you have three main building blocks.
1). The physical disk partition that you use as LVM physical volume (PV). In your case it seems to be /dev/sda3 with size 928GB.

I don't know that command, and not sure what exactly you mean by 'scrub'.
Basically after you remove a disk/member from the array (for example the mentioned sdb1), and zero its superblock, you are...
Sorry, my bad that I didn't mention the backup file parameter in my grow command. I thought you had that clear from your tutorial link. The --grow reshape is basically asking you for path and...
I assumed you want to use this as a learning opportunity too. Otherwise and as you already said you have backup of the data, like TheFu says, much faster and better way is to dynamite the array and...
As far as I see in mdadm -D sdb1 is not marked as failed yet. Despite any smart errors.
So, you have two ways to proceed.
1). Ignore the smart info for now, and shrink the array from 8 to 6...
Related to the mdadm shrink, the new size will be 5x members for data, and in mdadm -D you have the size of each member = 488253440. So according to that you first need to temporary shrink the array...
Good, I see you use partition as raid members (like /dev/sdb1) and not the whole unpartitioned disk (like /dev/sdb). That is a good best practice with mdadm but some people don't follow it. When...
First of all, mdadm.conf is not very relevant for shrinking. The ARRAY definition in that file basically just tells to assemble an array with all members (superblocks) with specific UUID present.

I do not use kvm but I would focus much more on the "not bootable disk" message.
Maybe it somehow lost the boot flag inside the VM or the MBR/UEFI sectors? Or a /boot parttion if separate?
PS:...
I still think you are doing it wrong. You say you created two new arrays on the new disks. Why their ARRAY definitions are not in mdadm.conf?
Instead of focusing so much on 'AUTO -all' I would...
After rereading post #3 I still fail to understand.
You have an array in the server and you want to add an older array to copy data over. Is that correct?
If that is so, then you want the...
The first array created is always md0, then md1 etc. From my experience ubuntu uses md127 is some cases and more as a random value.
In any case I see you do not have any ARRAY definition in the...
Actually since you are using ufw which is only a front for iptables I think you need to search what is the process to add that option through ufw. I don't use ufw so I don't have the commands at...
I think you are missing to do NAT for traffic going outside. So it doesn't know to come back correctly.
Try this as a simple test (the setting will not stay there after reboots, it is just for a...
If you were able to do it like that, I am always more in favor of adding the new disk in parallel, and migrate the data. Rather than cloning. Things can go wrong. For example, did the new disk have...
What exactly are you using to power off the server, is it 'sudo poweroff'? And for restart you use 'sudo reboot'?
It might be a clash with your hardware or another thing. In any case I wouldn't be...
Even for local connections I would suggest you get used to use scp and then you will have more experience with it when you need to use it in other situations.
To move or copy files within the same...
Did you consider using scp instead? The thing is that ftp is very old and quite unsecure protocol. You should never open ftp to your web server over the internet, and not to the /srv directory.

Review these short instructions how to allow remote conections to mysql and see if it helps. I think by default it listens only to local connections, so probably you will have to do the part with the...
OK, so ping works remotely but 3306 doesn't. Did you set up mysql correctly? I don't remember much details, get on google some tutorials to set up and troubleshoot mysql and follow them in parts...
In general, it is true that you can use app on one server and db on another. In your case, you have various things to check to make sure you set up everything right.
Does telnet work? I believe...
You are right, completely. Any possible BIOS corruption needs to be addressed.
I was just thinking out loud that if my board is PCIe gen3 then speed of a standalone Kingston NV2 2TB disk should be...
Well, mine is a Supermicro X11SCL with PCIe gen3. But according to that my NVME speeds are also very poor. I don't have much time for deeper investigation but obviously I will have to find some time...
My mdadm raid1 array has two NVME disks and one SATA SSD disk, so it is not a fair comparison to yours because the SATA SSD will be limiting the writes speed. But here is what the fio results are:
