3 years of Model S ownership

September 26th 2013

On 26-09-2013 the day had finally arrived: Delivery of my Tesla Model S!

In the morning my Delivery Specialist send me this picture asking me if I was ready (with a smiley behind it 😉 ).

It was 3 years since I ordered my Model S, so I couldn’t wait to pick it up! (In the back you see the Blue Model S of my colleague)

Specifications

These are the options I chose for my Model S:

85kWh non-performance (RWD)
Pearl White
All Glass Panoramic Roof
Base 19″ wheels
Black Nappa Leather Interior
Piano Black Décor
Tech Package
Sound Studio Package
Active Air Suspension
Lighting Package
Parking Sensors
Twin Chargers (22kW)

Price: EUR 97.890,00 (Including all taxes)

Afterwards I swapped the 19″ base wheels for the 19″ Cyclone Grey. These wheels are no longer available.

September 2016

Fast forward 3 years and 141.466km: I’m still super happy with my Model S. Best car ever, hands down.

The 100.000km mark was hit at November 14th 2015 as I was almost home. Literally, I was just 200m away from my house. So I could stop I take a good picture.

Now, 3 years later it is well over 141.000km and will probably hit 150.000km somewhere in October.

The roadtrips I did in these 3 years were all over Europe:

3x: Octoberfest in München (DE): 2.000km
3x: To Prague (CZ): 2.2000km
3x: To Berlin (DE): 2.000km
2x: Northern Norway above the Arctic circle: 6.000km
2x: Summer roadtrip to Germany, Austria, Italy and Switzerland: 3.500km
1x: To Swansea in Wales (UK): 1.500km

Each of these trips were with either friends or my girlfriend. Awesome trips, each of them. All powered by the ever expanding SuperCharger network.

Over the Air software updates

Due to the over the Air software updates the car only got better and better in these 3 years. A few things (but not all of them) which were added:

Trip Planner using SuperChargers
Spotify integration (awesome!)
New UI
Calender sync
Slightly improved efficieny

All for free and while my car was parked at home. My other cars never got better over time, they always got worse.

Problems

In three years I’ve driven my car to a lot of places in Europe (see below). From the cold in Norway to the heat of Italy.

Did I have some issues? Yes, but to be clear: I was never stranded! It did not malfunction in such a way that it was disabled.

So what did I experience?

Humming drivetrain. It was replaced 3 times under warranty
Main contactor failure in battery. Reboot of car worked and contactor was replaced.
Fogging rear lights
Slave charger failure. Causing reduced charging speed with AC charging
Window washer pump failure.

Again, none of these issues left me stranded along the road. They were also all fixed under warranty except for the window washer pump. That was EUR 100 in total.

Maintenance

In total my S went for service 3 times. I figured once every year would be enough. I paid two invoices of EUR 700,00 each. The other ones were discounted from the referral credit I have at Tesla.

Including the washer fluid pump my total expenses on service and maintenance were EUR 800,00. Not bad I would say!

Energy Consumption

About 70% of my charging is done at home, the rest at SuperChargers and other (public) chargers.

There is a kWh meter in front of my charging station at home and I’ve used about 20.000kWh. Judging from my 70% ‘charge at home’ assumption my total energy usage in 3 years was roughly 28.000kWh.

28.000kWh / 141.000km = 198Wh/km, which is about what I see in my general consumption in the car.

Roadtrips

As I wrote above I undertook multiple Roadtrips in the three years, but the best trips I did were the trips to Wales, Norway and to Slovenia. I wrote blogs about two of them:

I didn’t write a blogpost about my roadtrip through Europe in June 2015, but you can see the route below (Prague, Austria, Slovenia, Austria, Germany, Netherlands).

I tried to draw the routes I’ve driven on a Google Maps overview.

Highlights

In the threee years I still think my trips to the Arctic are the highlights for me. However, there were more highlights, so I gathered a bunch of pictures I took and added them below in a random order.

Route 74 between Norway and Sweden:

Stuck on the arctic circle in Norway:

On the Lofoten Islands in Norway:

Octoberfest in München: (I’m the green blouse)

Charging at Fastned using 50kW CHAdeMO.

In the Belgian Ardennes:

On a train in Austria going towards Bad Gastein:

At the Slovenian <> Italian border:

Conclusion

After owning a Audi A3 2.0TDI (2007), Toyota Auris Hybrid (2011) and BMW M5 E39 (1999) I can saw that Model S is the best car I’ve ever owned. I love driving it and still enjoy every KM. (Except when stuck in traffic….). Even without Autopilot it is still an amazing car!

People still come up to me to ask things about the car and are really interested.

As I said. Best car ever. Period. I will never by a car which burns fossil fuel again.

My deposit for Model 3 was made at the day they opened. Waiting!

Chown Ceph OSD data directory using GNU Parallel

Starting with Ceph version Jewel (10.2.X) all daemons (MON and OSD) will run under the privileged user ceph. Prior to Jewel daemons were running under root which is a potential security issue.

This means data has to change ownership before a daemon running the Jewel code can run.

Chown data

As the Release Notes state you will have to chown all your data to ceph:ceph in /var/lib/ceph.

chown -R ceph:ceph /var/lib/ceph

On a system with multiple OSDs this might take a lot of time, using GNU Parallel you can save yourself a lot of time.

Static UID

The ceph User and Group have been assigned static UID and GIDs in the major distributions:

Fedora/CentOS/RHEL: 167:167
Debian/Ubuntu: 64045/64045

Chown in parallel

Using these commands you can chown the data in /var/lib/ceph much faster.

WARNING: Make sure the OSDs are stopped on the system before you continue!

Now you can run these commands (Ubuntu in this case):

find /var/lib/ceph/osd -maxdepth 1 -mindepth 1 -type d|parallel chown -R 64045:64045
chown 64045:64045 /var/lib/ceph
chown 64045:64045 /var/lib/ceph/*
chown 64045:64045 /var/lib/ceph/bootstrap-*/*

The first command will take the longest. I tested it on a system with 24 OSDs all containing about 800GB of data. That took roughly 20 minutes.

Calculating SLAAC IPv6 Address in Java

SLAAC

With IPv6 a host on a network can use StateLess Address AutoConfiguration (SLAAC) to configure it’s network.

Routers will send out Router Advertisements telling the network which subnet is used in the network.

Based on their MAC address (modified EUI-64) a host will then obtain a IPv6 it will use.

Java

For the Apache CloudStack project I had to write Java code which would take a subnet and a MAC address as an argument and would generate a IPv6 SLAAC address from it.

Combining subnet 2001:db8:100::/64 with MAC address 06:7a:88:00:00:8b yields IPv6 address 2001:db8:100:0:47a:88ff:fe00:8b.

/*
 * Java code using Java-ipv6 from Google Code to convert
 * a given IPv6 subnet and a MAC address into a IPv6 address

*/
import com.googlecode.ipv6.IPv6Address;
import com.googlecode.ipv6.IPv6Network;

public class IPv6EUI64 {
    public static IPv6Address EUI64Address(final IPv6Network cidr, final String macAddress) {
        if (cidr.getNetmask().asPrefixLength() > 64) {
            throw new IllegalArgumentException("IPv6 subnet " + cidr.toString() + " is not 64 bits or larger in size");
        }

        String mac[] = macAddress.toLowerCase().split(":");

        return IPv6Address.fromString(cidr.getFirst().toString() +
                Integer.toHexString(Integer.parseInt(mac[0], 16) ^ 2) +
                mac[1] + ":" + mac[2] + "ff:fe" + mac[3] +":" + mac[4] + mac[5]);
    }

    public static void main(String[] argv) {
        IPv6Network cidr = IPv6Network.fromString("2001:db8:100::/64");
        String mac = "06:7a:88:00:00:8b";
        IPv6Address eui64addr = EUI64Address(cidr, mac);

        /* This will print 2001:db8:100:0:47a:88ff:fe00:8b */
        System.out.println(eui64addr);
    }
}
