RobH added a comment. Well, we have @Mark's approval to use the on-site spares for this (as we have plenty.)
Now the only question is how best to implement. We could do as @Joe suggests and add the two additional disks as raid1 and extend the LVM onto them. Ideally, we setup future installs to be raid10 across all 4 disks. If we cannot afford any reimage time now, we can still do that. As @fgiunchedi points out, we'll want to ensure partman is updated so when reinstall does roll around, its not broken. @Smalyshev: If we can afford the downtime, I think its better longterm to reimage them with raid10 and a new lvm. If we cannot afford the downtime, then we can do as @joe suggests and simply raid1 add the new disks and extend the LVM. Please advise (both @smalyshev and anyone else with knowledge on the subject) I'll create a sub-task to pull and add the additional disks, but with a note not to install them without checking first. (Seating them shouldn't cause any issues, but we should be certain and actively monitoring the system during this.)
