This tutorial explains why running fsck on a mounted root filesystem fails, shows how to inspect the last check time with tune2fs, and provides step‑by‑step commands to create a forcefsck file, reboot, and verify that the root filesystem check was performed.
When a Linux server triggers a disk‑space alert, you can pinpoint the offending directories or files by using df to view overall usage, du (with depth or max‑depth) or find to list large items, and lsof +L1 to detect deleted files still holding space, then optionally adjust reserved space with tune2fs.
This guide explains practical commands like du, find, and lsof to locate large directories or deleted files consuming disk space, and shows how to adjust reserved filesystem space with tune2fs to reclaim lost capacity.
This tutorial explains why you cannot run fsck on a mounted root filesystem, shows how to inspect the last check with tune2fs, and provides a step‑by‑step method using a /forcefsck file to force a root filesystem check on the next reboot.
This guide explains how to use Linux commands like df, du, find, lsof, and tune2fs to locate large directories, uncover deleted files that still occupy space, and adjust reserved root space, enabling you to resolve unexpected disk‑usage alerts efficiently.
This guide explains how to diagnose unexpected disk usage on Linux servers by using df to view overall usage, du and find to pinpoint large directories or files, and lsof to uncover deleted files that still hold space, plus how to adjust reserved space with tune2fs.
This guide explains how to locate large directories or files consuming disk space on Linux servers using commands like df, du, find, and lsof, and shows how to free space occupied by deleted files or adjust reserved root space with tune2fs.
This guide shows Linux administrators how to use df, du, find, lsof, and tune2fs commands to locate large directories, uncover hidden space consumed by deleted files, and adjust filesystem reserved space, with step‑by‑step examples and screenshots.
This guide shows step‑by‑step Linux commands—df, du, find, lsof, and tune2fs—to pinpoint large directories, uncover hidden space used by deleted files, and adjust reserved root space, helping you resolve mysterious disk‑space alerts efficiently.
This guide explains how to locate large directories and files consuming disk space on Linux servers using commands like df, du, find, lsof, and tune2fs, and offers tips for handling hidden or deleted file usage.
Learn step-by-step methods to locate large directories and files consuming disk space on Linux servers, using commands like df, du, find, and lsof, plus tips for handling deleted files and adjusting reserved space with tune2fs to reclaim lost storage.
This guide explains how to diagnose unexpected disk usage on Linux by using df, du, find, and lsof commands, demonstrates efficient ways to locate large directories or deleted files, and shows how to adjust reserved space with tune2fs to reclaim lost storage.
When a large file is deleted on a Linux server but the '/' partition still reports 100% usage, a running process likely still holds the file open, preventing space reclamation; this article explains the cause, shows how to find deleted‑but‑in‑use files with lsof, and offers recovery steps such as killing processes, restarting services, truncating logs, and adjusting reserved block percentages.
When a huge file is removed on a Linux server but the root partition still shows 100% usage, the issue is usually caused by the file being held open by a process, reserved filesystem space, or delayed space reclamation, and can be resolved with commands like lsof, kill, or tune2fs.
