Corporate Linux

Virtualization madness

Had my first encounter of Linux, or specifically, a linux-like environment in a corporate environment. The IT peops were trying to setup an environment on Xenserver, and they had setup a storage space to copy a virtual machine image onto. But they kept running out of space. It took me a while to figure out what they were doing (wrong), though.

They were trying to copy onto the PV partition, and Xenserver had setup its environment to use LVM, so the PV partition was already allocated to the LVM system, and therefore had no space to copy onto.

After figuring out which LV was the one they wanted to use, I had problems mounting, with mount saying I had to specify the filesystem. After trying various switches with mount and specifying a filesystem (only NFS, ext, ext2 and ext3 were supported by Xenserver. No vfat, ntfs or btrfs. Admittedly, however, the Xenserver version the IT people were using was an older version), I soon found out that the IT people had created the storage space, but not done anything else. Therefore, that would explain why I couldn’t mount it — it hadn’t been formatted. So a simple mkfs.ext3 (remember ext4 wasn’t supported) on the block device in /dev/mapper/ meant I could mount it without specifying filesystem. scp’ing into the server and copying into the path proved it worked.

 

Retraining 10K

After the Christmas and (upcoming) New Year celebrations and obligatory over-indulging of food, I, like many people will be trying to shift the extra weight in the new year. So, with the help of Endomondo, I’m going to train up again for a 10K — not a 10K race this time, just try to get up to the 10K distance again, then take it up to distance Half Marathon for the second half of the year and/or early 2015. The training plan is over half a year and I stretched it out to its maximum length deliberately to allow me as gradual work up to 10K.

I know I can do 10K, I did a race earlier this year (Chickenshed 10K), but after slacking off because of weather, I need to get back into it.

10K Training Plan

Devoted dog stays by side of dead companion despite sub-zero temperatures

Warning: Some people may find the following video distressing

A heart-wrenching video has emerged of a loyal dog watching over a dead companion for a whole night, despite temperatures plunging to -13 Celsius.

The incredibly sad footage was captured by locals in the city of Yinchuan in north-west China, after they noticed the steadfast dog sitting with the deceased animal despite cars raging past on the busy road.

Residents placed a stool next to them to prevent vehicles from hitting them, on the night of December 22 when the dog is believed to have died.

The deceased dog was then taken from the road to be buried in a park nearby – and its friend watched over until the very end.

North Circular crash: Two arrested after three die in collision with lorry travelling in opposite direction

Metro

Three people have died and two arrested after a car scaled a central reservation and collided with a lorry travelling in the opposite direction.

The Subaru Impreza was on the westbound carriage of the North Circular in London, near Arnos Grove, when it crashed into a vehicle travelling eastbound just after midnight.

Police and the London Fire Brigade attended the incident on the A406, in which a Vauxhall Astra was also involved.

Two men from the Astra were taken to hospital with minor injuries and both were arrested on suspicion of causing death by dangerous driving.

One has been discharged but the other currently remains in hospital.

The driver of the lorry also suffered minor injuries.

All three people who died were in the Subaru vehicle and their next of kin have yet to be informed.

Emergency crews are currently still on the scene, with the eastbound carriageway at Bowes…
