Growing 2-disk RAID1 array to a 4-disk RAID10 array in Debian

Question: I have a two-disk RAID-1 array in mdadm, and I purchased two more disks. How can I grow the array to use the new disks?

Answer: This took some strategy and time. In short, we install the disks, create a new RAID-10 with two missing disks, copy data over, and replace disks one at a time.

Digital Ocean, you’re awesome!

I must say, without a doubt, that Digital Ocean is one of the best companies available for hosting services. This is not a sales pitch, but an actual account of what has happened since I joined them over a year ago.

Hello world! We’re back

Welcome back to Talk About IT! We had a bit of a mishap, so all the previous content is gone. Backup, backup backup! Luckily, all the customer data has been recovered, with no loss. The server has been reconfigured, with a proper RAID setup, and off-site backups. It is going to make things a lot easier to recover, hopefully! Once the extra computers I’ve ordered have arrived, I’ll work on setting up haproxy and getting some clustering going.
