On: Hetzner launches three new dedicated servers

[Symbiote]

I'm not sure what "deactivating RAID" means.

They will all be hot-swap disks. You remove the old disk and slide in the new one (or in this case, tell them to do it). The RAID system rebuilds the array in the background over the next few hours.

During that time you will lose data if it's RAID 5 and another disk fails.

mdadm --manage <array> --remove <failed disk>

so your machine doesn't have a fit when the disk is detached. Or equivalent.

Presumably he means detaching the disk from your RAID solution so it doesn't freak out when it's physically removed and replaced.

I am using software raid servers, as other commenters say is not a hot swapping disks operation, is cold swap :D
