CEPH-VOLUME-SYSTEMD(8)

✨ NAME ✨

ceph-volume-systemd — the lil systemd helper tool for ceph-volume 💅

---

🎀 SYNOPSIS 🎀

ceph-volume-systemd systemd instance name

---

🦋 DESCRIPTION 🦋

okay so bestie, ceph-volume-systemd is a systemd helper tool 🫶 It gets input from (dynamically created) systemd units so that activation of OSDs can proceed, no cap.

What does it do with that input? It translates it into a system call to ceph-volume — and listen, it's for activation purposes only. That's it. That's the whole job. She's a one-trick pony and she ate. 👑

---

🌸 EXAMPLES 🌸

Its input is the systemd instance name (that's the %i u see in a systemd unit btw, iykyk) and it should be in this format:

<ceph-volume subcommand>-<extra metadata>

In the case of lvm a call could look like this:

/usr/bin/ceph-volume-systemd lvm-0-8715BEB4-15C5-49DE-BA6F-401086EC7B41

Which in turn will call ceph-volume in exactly this way:

ceph-volume lvm trigger  0-8715BEB4-15C5-49DE-BA6F-401086EC7B41

Any other subcommand will need to have implemented a trigger command that can consume the extra metadata in this format. so like… build that first fr fr 💀
