VFS_COMMIT(8)

💖 VFS_COMMIT — the manual page, but make it make sense 💖

okay bestie, welcome to vfs_commit(8), a.k.a. System Administration tools realness. this is the page about flushing your dirty data at specified intervals (yes that's the actual NAME section, i'm not being weird, that's literally what it does 🫶).

---

✨ NAME ✨

vfs_commit — flush dirty data at specified intervals

---

✨ SYNOPSIS ✨

vfs objects = commit

---

🌸 DESCRIPTION 🌸

so this VFS module is part of the samba(7) suite, okurrr 💅. the vfs_commit VFS module keeps track of how much data has been written to a file, and it synchronizes that data to disk when a specified amount accumulates. it's literally a little accountant for your bytes, and when the pile gets big enough it goes "okay flush it" 📊💾.

vfs_commit is useful in two circumstances, and the manpage is very clear on this so listen up:

• first: if you have very precious data 😭, the impact of unexpected power loss can be minimized by using a small commit:dthresh value. small threshold = more frequent saves = less crying when the lights go out.
• second: write performance can be improved on some systems by flushing file data early and at regular intervals. so sometimes committing early is highkey a glow-up for speed 🔥.

This module is stackable — yes bestie, it stacks. 👑

---

💅 OPTIONS 💅

• commit:dthresh = BYTES — synchronize file data each time the specified number of bytes has been written. like a vibe check for your write buffer, but with actual consequences ✨.

The following suffixes may be applied to BYTES:

• K — BYTES is a number of kilobytes
• M — BYTES is a number of megabytes
• G — BYTES is a number of gigabytes

---

🎀 EXAMPLES 🎀

Synchronize the file data on the [precious] share after every 512 kilobytes (524288 bytes) of data is written. that's it, that's the config, and no cap it's iconic:

   [precious]
path = /data/precious
vfs objects = commit
commit:dthresh = 512K

---

💀 CAVEATS 💀

On some systems, the data synchronization performed by commit may reduce performance. yeah. i know. the thing that sometimes helps performance can also sometimes hurt performance. it's giving chaos, it's giving "it depends", it's giving test it on your own system fr fr 🙈.

🌈 VERSION 🌈

This man page is part of version 4.24.7-Ubuntu-4.24.7+dfsg-1ubuntu1 of the Samba suite.

👑 AUTHOR 👑

The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed. legends only, honestly ✨🦋.

okay that's the whole page, you ate it, go commit some bytes 🍓💜 — and for the cute sign-off: this little masterpiece is from Samba 4.24.7-Ubuntu-4.24.7+dfsg-1ubuntu1, dated 09/13/2026, and it lived its best life on the VFS_COMMIT(8) page of the System Administration tools manual. periodt. 💖👑
