# Entropy Volume

The Dankserver entropy volume is a RAID-backed LUKS filesystem mounted at
`/mnt/entropy`. The command-line helper reuses the host's desktop-integrated
`udisks2`, `crypttab`, and `fstab` configuration; it does not store or handle
the passphrase itself.

## Command-line mount

```bash
/home/dank/serverAppConfigs/scripts/mount-entropy.sh
```

Run it as the normal desktop user (`dank`), not from a root shell. `udisksctl`
will securely prompt for the LUKS passphrase. `sudo mount /mnt/entropy` then
uses the existing `/etc/fstab` entry, preserving its options:

```text
nosuid,nodev
```

The existing mountpoint is owned by `dank:dankserver` with mode `0755`; the
helper deliberately does not run `chmod` or `chown`, so it cannot silently
change those permissions.

## Device path

The current storage chain is:

```text
/dev/md0 -> LUKS UUID cd86c728-459e-4f3a-bcc2-41ecf84685ec
         -> ext4 label entropy
         -> /mnt/entropy
```

The helper checks that `/dev/md0` exists and exits successfully if the volume
is already mounted. It is intentionally specific to this host and volume:
that avoids accidentally unlocking or mounting a different disk.
