LCTL-SNAPSHOT_MOUNT(8)

💅 lctl-snapshot_mount — Lustre Configuration Utilities, section 8

okay bestie, gather round, because we're talking about lctl-snapshot_mount from the Lustre Configuration Utilities gang, and it's giving very specific energy. ✨

🌸 NAME 🌸

lctl-snapshot_mount — mount a Lustre snapshot. that's it, that's the whole job, and she does it slayfully. 💖

🎀 SYNOPSIS 🎀

lctl snapshot_mount {-F|--fsname FSNAME} [-h|--help] {-n|--name SSNAME}
                    [-r|--rsh REMOTE_SHELL]

✨ DESCRIPTION ✨

So what does she actually do? She mounts the snapshot you point at on the servers. That's the move. 🫶

Here's the part where you have to pay attention though, because it's important: a mounted snapshot is a read-only filesystem, which means mounted snapshots cannot be renamed. no, not even if you ask nicely. 😭

And listen — it is the user's duty to mount the client to the snapshot when needed. that client must be mounted in read-only mode with -o ro. that's on you, not on her. you've been warned, bestie. 💀

NOTE: the snapshot has its own fsname that is different from the original filesystem fsname. and the way you find it out?? you query it via snapshot_list. iykyk. 🔥

👑 OPTIONS 👑

• -F, --fsname FSNAME — the filesystem name. you gotta say which one, periodt.
• -h, --help — for help information. she will explain herself. iconic behaviour.
• -n, --name SSNAME — the name of the snapshot you want mounted. this one must be specified, no skipping, no "eh I'll figure it out", specify it. 🌈
• -r, --rsh REMOTE_SHELL — pick which shell she uses to communicate with remote targets. the default value is ssh. and heads up: it is the system admin's duty to guarantee that the specified REMOTE_SHELL works well among targets without password authentication. so like… if your ssh isn't passwordless between the targets, that's a you problem, not a her problem. 🙈
