How to work with multiple disks?

Question

linux

There is a server on which there is a database. On the server, there are 2tb of space. The place ends.

I took another disk and added it according to the instructions https ://upcloud.com/community/tutorials/adding-rem....
Now it looks like this:

NAME   MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda    252:0    0  1960G  0 disk 
└─vda1 252:1    0  1960G  0 part /
vdb    252:16   0  400G  0 disk 
└─vdb1 252:17   0  400G  0 part /disk1

The database is spinning in docker and the volume is connected to /var/lib/database

How to work with a connected disk?

Answer 1

If the database does not fit on one of the disks, then there are several options.

1. Partitioning MyQSL
   
2. Raid
   
3. LVM
   

The last two, without redundancy, are unreliable.

Answer 2

Most likely, you are accumulating historical data that can be aggregated and archived or transferred to cheaper media.
Or, as Sanes correctly said - to partition.
