Outages and other stuff

Well that took longer than I thought it would (site being down!). It’s interesting trying to get a computer server stack just right – I’m close with this build but it’s something that you have to keep on top of. Hence it took me a week or so to get the site up again – and I may have a hardware issue to sort out but that’s a story for another day, but also part of the reason it took me a while to re build. But I must also admit that the last build stood the test of time (about 2-3 years) so it’s not all bad.

Computer

Onward and up ward, the next phase is a blue green development enviroument so that hopefully this won’t happen again. We learn from our mistakes!

Setting up software based raid

This is a very quick and dirty collection of notes to just get you up and running

View existing drives

lsblk -o NAME,SIZE,FSTYPE,TYPE,MOUNTPOINT

Create raid array

sudo mdadm –create –verbose /dev/md0 –level=6 –raid-devices=4 /dev/sda /dev/sdb /dev/sde /dev/sdd

 

Observe process of building

watch -n 3 -d cat /proc/mdstat
