LCTL-LCFG_FORK(8)

✨ NAME ✨

lctl-lcfg_fork — duplicate a filesystem config llog and rename it, bestie 💅

okay so this is the manual page for lctl-lcfg_fork, living in the Lustre Configuration Utilities section (that's section 8, for the sysadmin girlies 🫶).

---

🌸 SYNOPSIS 🌸

lctl lcfg_fork FSNAME NEWNAME

---

💖 DESCRIPTION 💖

So lcfg_fork — and yes she also answers to her alias fork_lcfg, iconic dual naming honestly — generates a brand new Lustre configuration llog for a filesystem called NEWNAME, and she builds it off the existing Lustre filesystem configuration for FSNAME. 🌈

Now here's the part that matters, and I need you to actually read this part: it is not simply a copy of FSNAME to new configuration files named NEWNAME. The way that it ALSO replaces all instances of FSNAME inside the configuration with NEWNAME as the filesystem name. Like, every single one. No cap. 🔥

So what is she even for? Two whole uses, periodt:

• backing up the system configuration 💾
• generating configuration for the snapshot that has the same configuration as the original filesystem but with different filesystem names 🦋

---

🎀 AVAILABILITY 🎀

lctl-lcfg_fork has been part of the lustre(7) filesystem package since release 2.10.0. She's been here a minute, and she ate. 👑
