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

Interesting morning today. My brakes seized up on my car (Skoda Fabia Greenline), with an ABS system warning light, meaning I was fighting my brakes trying to move my car. Pulled in 200 metres down the road, turned my car around and went back up the hill, and reparked it. Turned the engine off, restarted it and the light disappeared, proceeded to work without much further problems. Whether or not it pops back up again when I drive home is another matter….
