A failed powersupply was my excuse to upgrade most of the other internals of the desktop computer too. Some notes on adding a disk to LVM, following Suji's notes from 2007 (all of these require sudo):

```
fdisk /dev/sdd
```
(create a primary partition, type "8E" Linux LVM, exit with "w")
```
mkfs -t ext3  /dev/sdd1
```
~~(this will create the file-system. option "-c" which checks for bad sectors is recommended by some, but takes ages to complete)~~ (see comments)
```
pvcreate /dev/sdd1
```
(this will create a physical volume)
```
pvdisplay
```
will now list all the physical volumes and the newly created one should be visible.
```
vgdisplay
```
will list the volume groups. On my machine there's one named "datadisk"
```
vgextend datadisk /dev/sdd1
```
(this will extend the volume group with the new disk)
```
vgdisplay -v datadisk
```
will now display info on the volume group. The new disk should show up in the list of physical volumes.
```
lvextend -l100%VG /dev/datadisk/data
```
(this will extend the logical volume so that the new size is 100% of available space in the volume-group)
```
resize2fs /dev/datadisk/data
```
(this will resize the logical volume. takes a long time to complete with big disks and there is no progress bar/display)
finally you can check that the mounted volume group is actually re-sized to the new size and has lots of free space:
```
df -h
```

There is more info in the LVM-HOWTO.

Friday 48k

Thursday 44k

Mylly hiihto (link describes the course in the reverse direction we did it)

Wednesday 42k

Around Ylläs. Again the snow is soft and slow towards the afternoon. And it's raining.

Tuesday 40k

About +1C already in the morning, so in the sun it gets very warm, soft, and slow by the afternoon.

Monday 57k

A flight north to Kittilä to escape the spring in Helsinki and enjoy what's left of the winter during a week of skiing in Äkäslompolo (Ylläs).
Started off the week with a 57km trip:

Saturday 20k bike ride

Biking in the early spring is a messy business. Most of the roads are now free from ice and snow, but the bike-paths are all covered in remains of sand and gravel from the winter with the occasional patch of ice, snow, or a wet slurry. Even with reasonable fenders on the bike your back and legs are pretty much covered in mud after an hour.

Data is from my latest gps-toy, which supports openstreetmap! (20.1k in 58mins, avg-speed 20.8km/h, avg-HR 148, temp +0 C)

Come spring/summer the plan is to put in some longer training rides to complement the running training. Maybe even some brevets on the new road-bike.

The temperature measurement circuit or transducer on the edge 800 seems to have a long-ish time-constant of about 15 minutes:
