Add new disk to debian

Hello,
I am using Debian 11, server ProLiant DL320e Gen8 v2, E3-1231v3, 32 GB, 2x1 TB. During install i used manuall settings for disk - for beginners and was added disk with name sda1 - second is with name sdb. In my debian, ispconfig etc. i can see only first added disk sda1.

Is here any easy way without lost data how can i add second disk to use it? I have to boot debian from ISO file and there choose something like recovery mode, go to settings disk in non graphical settings and there add second disk? I have no access to bios.

I am not sure why here is disks sdb and sda with the same used space.

Code:

In ispconfig i can see

Code:

udev    devtmpfs    16G    0    16G    0%    /dev
tmpfs    tmpfs    3.2G    680K    3.2G    1%    /run
/dev/sda1    ext4    915G    3.6G    865G    1%    /

 

What shows

Code:

df -hT

If that sdb disk is not used in any way, i.e. not mounted and not part of RAID pack, you can mount it to suitable mountpoint, /srv or /opt for example.
You could have done this during installation of Debian, the disk setup part shows all disks and allows choosing file system and mount point.

Thank you. I will check it. This command shows me

Code:

udev           devtmpfs   16G     0   16G   0% /dev
tmpfs          tmpfs     3.2G  660K  3.2G   1% /run

I am using for my installation of debian sdb1 as i can see in ispconfig, so i have to add sda

 

I think @till answer is for another thread?

 

Yes, but this was correct, i found it and solved it, found it in vim file

 

I check my disks and not sure why there is same space and quota for sda and sdb. At all most probably my system is on sdb1, so maybe i should try to format sda and try to follow manual which sent Taleman.

Or do you think that is better way to load iso file of debian and in any rescue mode try to add and choose file system and mount point for sda?

 

If you are unsure about mounting disks, I would suggest installing the system fresh and paying attention in the disk setup part to set file systems on both disks and mount them to suitable places. If one disk is mouted at / then you have to decide where the other is mounted. Preferably a directory where you need 900 GB disk space.
If you can not re-install:

No. It might be possible that way but very complicated.

 

I solved it. Just used mount command and choose folder for this disk, /mnt, for sda is /
