LCTL-NODEMAP-DEL-IDMAP(8)

💖 LCTL-NODEMAP-DEL-IDMAP 💖

okay bestie, so this page lives in section 8 of the lctl-node...del_idmap manual, and it's literally your cheat code for yeeting an idmap out of a nodemap. stay with me, it's giving "surgical deletion" energy 🦋

---

✨ NAME ✨

lctl-nodemap_del_idmap — delete an existing idmap from a nodemap

---

🎀 SYNOPSIS 🎀

lctl nodemap_del_idmap or
lctl nodemap del_idmap --name NODEMAP_NAME --idtype {uid|gid|projid}
                       --idmap CLIENTID[-CLIENTID_END]:FSID[-FSID_END]

---

💅 DESCRIPTION 💅

nodemap_del_idmap deletes an idmap from a nodemap. and like… what happens to the users, groups, or projects inside that nodemap who were rocking that ID? they get squashed 😭 — but only if the trusted flag is not enabled. no cap.

---

🌸 OPTIONS 🌸

• --name NODEMAP_NAME — the name of the nodemap you're deleting this idmap from. tell me which one, bestie, I'm not a mind reader 💅
• --idtype {uid|gid|projid} — pick your fighter: "uid" or "gid" or "projid", depending on whether it's a user, group, or project ID mapping that's getting removed 👑
• --idmap CLIENTID[-CLIENTID_END]:FSID[-FSID_END] — the actual identity map you want to delete. periodt. ✨

---

🌈 EXAMPLES 🌈

watch me cook 🔥

# lctl nodemap_del_idmap --name remotesite --idtype uid --idmap 2001:1001
# lctl nodemap_del_idmap --name remotesite --idtype gid --idmap 2002:1002
# lctl nodemap_del_idmap --name remotesite --idtype projid --idmap 33:1
# lctl nodemap_add_idmap --name othersite --idtype uid --idmap 0-999:9000

(that last one is an add, bestie — nodemap_add_idmap, not delete. do not come for me, I'm just reading the page 💀)
