A self dispatch has been ordered with Dell. Work Order: SR952745470

@Gehel The disk arrived, the disks are internal and the server will need to be taken down to replace. Let me know when you're ready for me to swap disk.

I'll take down the server right now, we should be able to live with 2 elasticsearch backends only without any issue. Let me know when the server is up again and I'll do a check before putting in back in the cluster.
