I'm really new to linux. I have a server hosted with a reputable company and I just ran out of space on my /var directory. I knew this when i uploaded files and figured that there was a write error.I do know that the server I've purchased has two hard drives. I'm confused at several things :Mounting = Putting your hard drive into a local directory so that directory will act as storage now?How you can add more space(mounting?) to your /var or eg : /home2 directory?[i made this directory myself]This is my current fdisk -lLooking at this, I am again filled with questions:Does Boot and * means it's booted up on boot/reboot?It says Disk /dev/sda at the top, does sda1,sda2,sda3 stand for partitions on the sda drive? if so, is this the same for sdb?Then there's the dev/md1 and /dev/md2, This is where i'm greatly confused about.. when purchasing my server the specs were only 2 SSD drives.. why are there 3 drives at 400GB for /dev/sda, /dev/sdb and /dev/md2?What is the difference between md1 and sda?I've also browsed online thoroughly, so here's my mount (probably because you'll need it? i'm not sure..)My /etc/fstab file    # <file system> <mount point>   <type>  <options>   <dump>  <pass>/dev/md1    /   ext4    errors=remount-ro,relatime,discard  0   1/dev/md2    /home   ext4    defaults,relatime,discard   1   2/dev/sda3   swap    swap    defaults    0   0/dev/sdb3   swap    swap    defaults    0   0proc        /proc   proc    defaults        0   0sysfs       /sys    sysfs   defaults        0   0devtmpfs    /dev    devtmpfs    rw  0   0Thank you a lot for looking through this and assisting me! I greatly thank you for your time!
