Disk & Filesystem Management (Du/Df/Lsblk/Fstrim)
Get your mount points sorted without staring at a wall of text
🧩 The Challenge
Dealing with a server that has twenty-odd disks and multiple mount points usually means staring at the absolute mess that is the standard df output. It’s a headache trying to figure out which physical drive maps to which application path when everything is a jumble of UUIDs and truncated names.
đź’ˇ The Fix
Start using lsblk to actually visualize the hardware hierarchy instead of squinting at df. You’ll see exactly what is mounted where and how the partitions nest together in a clean tree structure.
lsblk -o NAME,SIZE,TYPE,MOUNTPOINT,FSTYPE⚙️ Why It Works
Adding the -o flag lets you strip away the junk columns you don’t care about so you can actually read the output. It turns a chaotic wall of text into a simple tree that maps your physical storage directly to the filesystem logic.
🚀 Pro-Tip: Stick -p in there if you need to see the full path of the block devices, which helps immensely when you are dealing with symlinks or multipath devices.
