# fstrim-lxc Script
|
||||
|
||||
Kleines Host-Skript für **Proxmox VE**, das per `pct fstrim <VMID>` TRIM/Discard für **LXC-Container** ausführt.
|
||||
Es unterstützt alle laufenden Container oder eine gezielte ID-Liste – sowie einen interaktiven Modus.
|
||||
|
||||
## Voraussetzungen
|
||||
- Proxmox VE Host (mit `pct`)
|
||||
- Ausführung als `root`
|
||||
- Container müssen **laufen** (gestoppte werden übersprungen)
|
||||
|
||||
Wichtig: Link für Lizenz anpassen.
|
||||
## Aufruf
|
||||
|
||||
```bash
|
||||
# Alle LXC-Container trimmen
|
||||
./fstrim-lxc.sh --all
|
||||
|
||||
# Ausgewählte Container per ID-Liste (kommagetrennt)
|
||||
./fstrim-lxc.sh -i 102,103
|
||||
|
||||
# Interaktiver Modus (Menü: alle oder IDs eingeben)
|
||||
./fstrim-lxc.sh
|
||||
```
|
||||
|
||||
## Beispiele
|
||||
|
||||
### Manuell
|
||||
```bash
|
||||
# Alle laufenden Container
|
||||
bash ./fstrim-lxc.sh --all
|
||||
|
||||
# Nur bestimmte IDs
|
||||
bash ./fstrim-lxc.sh -i 102,105,117
|
||||
```
|
||||
|
||||
### Automatisierung (Cron)
|
||||
Wöchentlich sonntags um 03:30 Uhr alle LXCs trimmen:
|
||||
|
||||
```cron
|
||||
# /etc/crontab oder per crontab -e
|
||||
30 3 * * 0 root /usr/bin/bash /root/scripts/fstrim-lxc.sh --all >> /var/log/fstrim-lxc.log 2>&1
|
||||
```
|
||||
|
||||
## Hinweise
|
||||
- Das Skript führt **keine** Containerstarts/-stops durch.
|
||||
- TRIM wirkt hostseitig: Speicher wird am Storage-Backend (SSD / Thin-Provisioning) freigegeben.
