tunegfs2(8)

💅 tunegfs2 — the manual page, but make it slay ✨

okay so bestie, welcome to tunegfs2(8) from the System Manager's Manual 🎀 — this is the little tool that lets you peek at and mess with your GFS/GFS2 superblocks. yes, the superblock. the main character of the filesystem. 👑

✨ NAME ✨

tunegfs2 — View and manipulate gfs2 superblocks 🦋

🌸 SYNOPSIS 🌸

tunegfs2 [OPTIONS] /dev/blockdevice

💖 DESCRIPTION 💖

so tunegfs2 is the girl who lets you view and manipulate the values sitting inside a GFS or GFS2 superblock. she can modify the UUID (GFS2 only, bestie, don't get it twisted), the label, the lockproto and the locktable. 💅

here's the tea though: the values in the GFS2 superblock are read only on mount. so if you change stuff on a live filesystem, none of it takes effect until the next time it gets mounted. 😭 and because of that, making changes on a live filesystem is not recommended. like, at all. don't do it. no cap.

👑 OPTIONS 👑

• -h — prints out usage information for this command. the little "hey here's how you use me" moment 🫶
• -l — list contents of the filesystem superblock. this includes the current values of the parameters that can be set by this program. it's giving receipts ✨
• -L <label> — change the filesystem label. heads up bestie: the GFS2 filesystem label is also the locktable name. they're the same girl. two jobs, one icon. 👑
• -o [lockproto=<proto>] [locktable=<table>] — set mount options. currently supported options include lockproto and locktable. that's the whole roster rn 💅
• -U <uuid> — set the filesystem UUID. glow-up for your identity 🌈
• -V — print out the information on the version of the tool. version check, periodt ⭐
• -r <version> — set the filesystem format version. vintage or new, your call 🎀

and that's the whole page, bestie!! this was tunegfs2(8) from the System Manager's Manual, brought to you with love, sparkle and absolutely zero live-filesystem edits 💖 stay safe, read your superblocks, and slay 🦋✨
