Yes, I know the title is not good enough for many of you but not for me. I’m in a hurry when I need this feature. Lucky me, the process is not difficult at all.
Problem. One of vps server that reside in digitalocean need to upgrade the storage as the report told me about the service not run well due to unsufficient storage.
Further investigation tell me the truth.
df -H
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 32G 30G 278M 100% /
tmpfs 523M 0 523M 0% /dev/shm
/home/usertmp_donotdelete
4.0G 12M 3.8G 1% /tmp
Well, only 278M left after delete log file and a few old backup files.
I know if digitalocean provide volume service and now its time to use it 🙂
Click the ‘Add Volume’ button lead me to this display.
Enter size for this volume and set the name. Hit Create Volume button to start create the space.
Wow, really cool. You just need to copy and the command. It just works!
Step1 :
sudo mkfs.ext4 -F /dev/disk/by-id/scsi-0DO_Volume_skripsi

This filesystem will be automatically checked every 36 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
Step 2 :
sudo mkdir -p /mnt/skripsi; sudo mount -o discard,defaults /dev/disk/by-id/scsi-0DO_Volume_skripsi /mnt/skripsi; echo /dev/disk/by-id/scsi-0DO_Volume_skripsi /mnt/skripsi ext4 defaults,nofail,discard 0 0 | sudo tee -a /etc/fstab
Check if mounted
mount
/dev/vda1 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
/home/usertmp_donotdelete on /tmp type ext4 (rw,noexec,nosuid,loop=/dev/loop0)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sda on /mnt/skripsi type ext4 (rw,discard)
Wow, in less than 5 minutes the job gets done and everyone happy 🙂
Thank You DigitalOcean, good work.
