[Adminsysters] SMART error meeting

[mara]

Does @donna or @gaba who did the server building and installation 
remember how the RAID is used? We might need to make use of the RAID to 
backup the whole disk, and then try and fix these sectors or deactivate 
them.

I made a possible date picker here for next week.

Expecting to take a few sessions, here is the relevant ticket with the 
manuals mentioned in Micha's email:
