We were doing a move of data within ESXi from 1 datastore to another to shrink datastores that were increased in size a bit more than needed.
~28TB of data, with just under 60TB showing free on the Compellent 9000/SC420, but it ran out of space during the migration.
I've deleted a 45TB datastore, as I had copied the data to a vSAN for our production upgrade last week. I can restore that data easily enough by cloning the production VM I created, as it's unconfigured and not in production yet.
The Compellent is being used for secondary storage for test environments, so it's not exactly production, but it being down right now wasn't something we had planned. (in 3 weeks when me rebuild the environments for the new software, yeah).
It's currently doing a RAID scrub, but I'm curious what else will need to be done to get it back up and "running". I can leave things on the vSAN for now to let things settle down...but with the Compellent being a couple years out of warranty, I don't have any support through Dell at the moment. I'm trying to avoid having to go back to them for support stuff if at all possible. There are still 3 Datastores, 2 of which have important(ish) info, and one that has a test lab environment that may be going away anyway as part of a rebuild, but I'd like to not have to delete anything more, considering I just blew away a 45TB datastore.
I have a couple 3.84TB SSDs as offline spares for the unit, but it didn't want to add them to the assigned disks. Not sure if its refusal to add them is related to Emergency Mode or not...but I do have disks available to me that I kept around as I knew we were out of warranty, so having official disks seemed like a smart idea at the time.
