There is another scenario, where 1 drive fails and Drobo has enough space to recreate redundancy with the remaining drives. Later (before you return from vacation in Medjugorje) another drive fails, but Drobo already rebuilt redundancy so you lose nothing.
Of course, that requires that all your data fits on the smallest 2 drives, which is not true in this case.
rdo, you’re mostly right. If enough drives fail, one at a time, so that you’re left with more data on the pack than usable space, the data will still be there and accessible. However, the pack isn’t protected from any further drive failures until you add enough capacity to cover the data and allow relayout to finish.
hi davek, have a look at my sig:
i did exactly that with 2 drobos.
have a search for syncback on the threads for fuller details… its very good (on windows) for verifying and helping to synchronise 1 drobo to the other. (make sure you practice safely first and read up about it before using, but some people just get a 2nd drobo and copy/paste their actual data files using their computers operating system.
