# ceph-volume-systemd(8)

systemd ceph-volume helper tool

## NAME

ceph-volume-systemd - systemd ceph-volume helper tool

## SYNOPSIS

```
ceph-volume-systemd systemd instance name
```

## DESCRIPTION

**ceph-volume-systemd** is a systemd helper tool that receives input from (dynamically created) systemd units so that activation of OSDs can proceed.

It translates the input into a system call to ceph-volume for activation purposes only.

## EXAMPLES

Its input is the **systemd instance name** (represented by **%i** in a systemd unit), and it should be in the following format:

```
<ceph-volume subcommand>-<extra metadata>
```

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

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

Which in turn will call **ceph-volume** in the following 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.

## AVAILABILITY

**ceph-volume-systemd** is part of Ceph, a massively scalable, open-source, distributed storage system. Please refer to the documentation at *http://docs.ceph.com/* for more information.
