VFS_SYNCOPS(8)

💅 NAME 💅

vfs_syncops — bestie, this one makes sure your meta data operations get performed synchronously. no cap. periodt. ✨

---

🦋 SYNOPSIS 🦋

vfs objects = syncops

---

👑 DESCRIPTION 👑

okay so first thing, this VFS module is literally part of the samba(7) suite. she's not out here alone, she has a whole family. 🫶

now the tea: some filesystems — and yes, even some journaled filesystems, iconic behavior — require that a fsync() be performed on many meta data operations to make sure the operation is genuinely guaranteed to still be in the filesystem after a power failure. like, we're not doing vibes-based durability here, bestie. 🔥

this matters especially for some cluster filesystems that are participating in a node failover system with clustered Samba. on those filesystems, the vfs_syncops VFS module provides a way to perform those operations safely. 💖

and yesss, this module is stackable. she plays well with others. 🧚

🌸 CONFIGURATION 🌸

listen, most of the performance loss with the vfs_syncops VFS module is in fsync on close(). like that's the main character of the slowdown fr fr. 😭 you can disable that with:

syncops:onclose = no

and that can be set either globally or per share. pick your fighter. 💅

on certain filesystems that only require the last data written to be fsync()'ed, you can disable the metadata synchronization of this module with:

syncops:onmeta = no

that option can also be set either globally or per share. no gatekeeping. ✨

and if you want her gone gone, the vfs_syncops VFS module can also be disabled completely for a share with:

syncops:disable = true

---

🎀 EXAMPLES 🎀

here's how you add syncops functionality for [share], ate and left no crumbs:

[share]
path = /data/share
vfs objects = syncops
syncops:onclose = no
