We have an ubuntu server with two SSD which host a few websites running on nginx, mysql, postfix etc...
I am so confused if we are using the 2 SSD correctly
On webmin system info page, it says :
61.50 GB used, 188.45 GB total
Unix commant
~# sudo lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL

sda 223.6G

`-sda3 linux_raid_member 190.7G NC-PH-0456-19:2

sdb 223.6G
|-sdb1 linux_raid_member 953M NC-PH-0456-19:0

`-sdb3 linux_raid_member 190.7G NC-PH-0456-19:2
`-md2 ext4 190.7G /
And df command:
Filesystem 1K-blocks Used Available Use% Mounted on
udev 16437532 0 16437532 0% /dev
tmpfs 3291052 9420 3281632 1% /run

So the total should be around 400GB ?
BTW, should we running the system on ssd1 and backup everything on ssd2 ?
