💖 defragfs.ocfs2 — the OCFS2 manual pages, bestie edition 💖

okay so. picture this: you're deep in the OCFS2 Manual Pages, and there's this one tool that just fixes your filesystem's whole situation. it's called defragfs.ocfs2 and honestly? she's iconic. let's get into it 🦋

✨ NAME ✨

defragfs.ocfs2 — online defragmenter for ocfs2 filesystem

no cap, that's the whole vibe. she defrags. while you're online. main character energy fr fr 💅

🌸 SYNOPSIS 🌸

defragfs.ocfs2 [-c] [-v] [-l] [-g] [-h][target]...

🎀 DESCRIPTION 🎀

so defragfs.ocfs2 reduces fragmentation of an ocfs2 based file. the file that gets targeted by defragfs.ocfs2 is created on an ocfs2 filesystem. the targeted file ends up with more contiguous blocks and that improves the file access speed. it's giving glow-up, it's giving organizational queen ✨

target is a regular file, a directory, or a device that is mounted as an ocfs2 filesystem. let's break that down because the details MATTER:

  • if target is a directory, defragfs.ocfs2 reduces fragmentation of all files in it.
  • if target is a device, defragfs.ocfs2 gets the mount point of it and reduces fragmentation of all files in this mount point.

periodt. 💅

💜 OPTIONS 💜

  • -c — prints the numbers of files that should be processed. like a little headcount before the party starts 🔥
  • -v — verbose mode, the current fragmentation count and the ideal fragmentation count are printed for each file.
⚠️ okay bestie listen: if this option is specified, target is never defragmented. it's just looking. window shopping. no purchase 🛍️
  • -l — defragfs.ocfs2 will run in low io mode, which means it will regularly yield cpu to allow other processes to run. she's polite. she shares. we love a considerate queen 🫶
  • -g — defragfs.ocfs2 regularly records the current progress. so if it is interrupted, the next time you run defragfs.ocfs2 with this option, it will resume from the recorded progress.
🚨 note that if this option is specified, other options are ignored and replaced by those that were recorded. it said "i remember everything" and it MEANT it 😭
  • -h — print help info. the classic. the helpful little angel 🧚

🦋 NOTES 🦋

defragfs.ocfs2 does not support files in lost+found directory. when target is a device or a mount point, defragfs.ocfs2 doesn't defragment files in mount point of other device. boundaries! respect them 🌈

💀 it is completely not recommended to run against a file while it is actively in another application. since the read/write of a file involves a dlm lock, this can result in a performance slowdown to both defragfs.ocfs2 and the application due to contention. like two besties fighting over the aux cord. don't do it.

if the file system's free space is fragmented, or if there is insufficient free space available, defragfs.ocfs2 may not be able to improve the file's fragmentation. she's talented but she's not a magician, she needs room to work 😭

non-privileged users can execute defragfs.ocfs2 to their own file. therefore, it is desirable to be executed by root user. 👑
