title: Repartitioning the home server
abstract: How I rethought and repartitioned my server.
---
I have owned Synology 920+ for some two years. Unfortunately, when I first got it, I made some assumptions that are no longer true and therefore this NAS is basically a glorofied Plex machine. A bad one, as the CPU is not powerful for any modern codec transcoding. Time to fix it!
## Durandal
The server (named Durandal) had all drives in Synology Hybrid Raid (SHR) configuration until recenly. When I first bought the device, I got three WD-RED 4 TB drives, which left one bay empty. Soon, the occupied space filled the three drives, and I expanded it with 6 TB - as SHR allows for mixing drive size. In adition, SHR1 allows for one drive failure.
The configuration looked like:
```
HDD1 HDD2 HDD3 HDD4
-------- -------- -------- ------------
| | | | | | | |
| WD-RED | | WD-RED | | WD-RED | | WD-RED |
| 4 TB | | 4 TB | | 4 TB | | 6 TB |
| | | | | | | |
-------- -------- -------- ------------
| |
---------------------------------------------------
Volume 1 (SHR1)
9.6 TB
```
This setup has the drawback of not allowing as much storage as required, and storing movie backups on volume with redundancy is an overkill.
## Vulcan
A few days ago, I rethought the current assumption, and the new ones are:
- I want to host application on the NAS
- I want to host my photographs (no more iCloud subscription)
- I want to store multimedia, but I don't care if I lose it.
This led to a new architecture based on two volumes:
```
HDD1 HDD2 HDD3 HDD4
-------- -------- -------- ------------
| | | | | | | |
| WD-RED | | WD-RED | | WD-RED | | WD-RED |
| 4 TB | | 4 TB | | 4 TB | | 6 TB |
| | | | | | | |
-------- -------- -------- ------------
CACHE1 CACHE2
-------- --------
| Samsung| | Samsung|
| 256 GB | | 256 GB |
-------- --------
| | | |
------------------------ ---------------------------
Volume 1 (SHR1) Volume 2 (RAID0)
3.5 TB 8.7 TB
```
Now I have a clear distinction between space for important stuff and for stuff I can recreate with ease. Having 3.5 TB is overkill here, as the drives will sooner fail than I will be able to fill them - currently, I store 520 GB in iCloud... and I pay for 2 TB as there is nothing in between. Having two 2 TB drives there would be much more economical
The total capacity is also significantly higher now. There will be things I'll want to secure that are on Volume 2, but since it won't be anything mission-critical, I can just use a USB Drive for this.
## The future
Since the server is ready, I think I'll strive for:
- adding new offsite backup (or 2) for Volume 1,
- leaving Plex (temporarily I use Samba shares),
- adding proper photo storage,
- adding a music server,
- adding DNS server,
- moving this site,
- moving my XMPP server,
- adding a VPN server,
- adding backup power for the NAS, modem, and router.
