💖 LFS-FLUSHCTX 💖

okay bestie, so this is a page from the Lustre User Utilities manual — it's lfs-flushctx, and no cap, it's the lil cleanup queen of your Lustre setup. let's get into it 🧚

---

✨ NAME ✨

lfs-flushctx — flush security context of current user.

like… it yeets your current user's security context. that's the whole vibe. 💅

---

🎀 SYNOPSIS 🎀

lfs flushctx [--help|-h] [-k] [-r] [rootpath]

---

🦋 DESCRIPTION 🦋

So the way that this works is: lfs flushctx flushes the security context of the current user — either for the Lustre file system you point at with rootpath, or for all mounted Lustre file systems if you don't give it a path. she's flexible like that. ✨

If -k is specified, it also proceeds to destroy the Kerberos credentials cache as well, by calling kdestroy. bye bye ticket 🎟️💀

If -r is specified, it reaps revoked keys from the session keyring. spring cleaning fr fr 🌸

---

🌈 OPTIONS 🌈

• -k — destroy the Kerberos credentials cache.
• -r — remove revoked keys from the session keyring.
• -h — print usage message.

---

🍓 EXAMPLES 🍓

First one is the recommended way of using the command, so like, take notes bestie 👑 — flush the security context of the current user for the Lustre file system mounted under /mnt/lustre, and destroy its Kerberos credentials cache, and reap revoked keys from its session keyring:

# lfs flushctx -k -r /mnt/lustre

And this one just simply flushes the security context of the current user for all mounted Lustre file systems:

# lfs flushctx
