One of my weekend project is growing virally and its mysql database is growing and I am running out of space. Here's what df -h looks like at the moment.

Filesystem Size Used Avail Use% Mounted on udev 126G 0 126G 0% /dev tmpfs 26G 1.0M 26G 1% /run /dev/md2 435G 368G 45G 90% / tmpfs 126G 0 126G 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 126G 0 126G 0% /sys/fs/cgroup /dev/md1 488M 75M 387M 17% /boot tmpfs 26G 0 26G 0% /run/user/0

So I asked hetzner to install 2 additional 960GB SSD and this is what lsblk -i looks like now.

NAME    MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
sda       8:0    0 447.1G  0 disk  
|-sda1    8:1    0     4G  0 part  
| `-md0   9:0    0     4G  0 raid1 [SWAP]
|-sda2    8:2    0   512M  0 part  
| `-md1   9:1    0 511.4M  0 raid1 /boot
`-sda3    8:3    0 442.6G  0 part  
  `-md2   9:2    0 442.5G  0 raid1 /
sdb       8:16   0 447.1G  0 disk  
|-sdb1    8:17   0     4G  0 part  
| `-md0   9:0    0     4G  0 raid1 [SWAP]
|-sdb2    8:18   0   512M  0 part  
| `-md1   9:1    0 511.4M  0 raid1 /boot
`-sdb3    8:19   0 442.6G  0 part  
  `-md2   9:2    0 442.5G  0 raid1 /
sdc       8:32   0 894.3G  0 disk  
sdd       8:48   0 894.3G  0 disk 

The problem is I don't know how to proceed from here. df -h still returns the same result. /dev/md2 is still 90% filled. Read quite a bit about gparted and repartitioning root folder or home folder but I guess I am just looking for the best pointers on how to learn to do this.

  • You have two additional disks that are unused at the moment. – RalfFriedl Jan 31 at 7:15
