💅 lctl-nodemap_del_range(8) — the Lustre Configuration Utilities glow-up

okay bestie so this is lctl-nodemap_del_range from the Lustre Configuration Utilities manual, section 8, and it's literally the girl whose whole job is removing things. we love a clean-up era. 🧹✨

✨ NAME ✨

lctl-nodemap_del_range — deletes an existing NID range from a nodemap. bye range! 🫶

🌸 SYNOPSIS 🌸

so there's two ways to run her, and she's not picky:

lctl nodemap_del_range

or

lctl nodemap del_range --name NODEMAP_NAME --range NID_RANGE

like yes, both forms eat. pick your fave. 👑

🦋 DESCRIPTION 🦋

so nodemap_del_range does exactly what it says on the tin: it deletes a NID range from a nodemap. that's the whole thing. no plot twist. 😌

and the bestie detail you need to know: the clients that were in that range get moved to the default nodemap. so they're not orphaned or anything, they just get sent home to default. it's giving "we're not kicking you out, we're just relocating you." 🏠💨

🎀 OPTIONS 🎀

  • --name NODEMAP_NAME — the name of the nodemap you're deleting this range from. tell her which map, she's not a mind reader. 🗺️
  • --range NID_RANGE — the NID range that should be deleted from the nodemap. this is the thing getting yeeted. 🗑️✨

🔥 EXAMPLES 🔥

here's her in her natural habitat, four times in a row because she's consistent:

# lctl nodemap_del_range --name remotesite --range 192.168.1.[1-254]@tcp
# lctl nodemap_del_range --name secondremotesite --range 192.168.2.[1-254]@tcp
# lctl nodemap_del_range --name thirdremotesite --range 2001:0db8::/32@tcp
# lctl nodemap_del_range --name fourthremotesite --range [1-60000]@kfi

look at the range syntax flexing too — IPv4 with the [1-254] range, IPv6 with 2001:0db8::/32@tcp, and the kfi one just raw [1-60000]@kfi. she does NOT discriminate. 🌈💯

⭐ AVAILABILITY ⭐

lctl nodemap_del_range is part of the lustre(7) filesystem package since release 2.6.0. so she's been around, she's a vet, she's not new here. 🧚👑
