Personally I appreciate the honesty and look for it in vendors, there are too many that cover up the truth (MS/Github etc...). However I agree that it doesn't look good for a storage company.
I agree with you. I’d like further transparency on this: why didn’t they anticipate that the array would be offline for this expansion? Expanding a storage environment can certainly be a mine-filled exercise for even the most experienced. But why was this expansion unexpectedly an offline operation? I’m not throwing shade here. I’m genuinely curious because I’ve been considering Borg and Borgbase for an upcoming proj…
With enough 22TB spinning drives nowadays you can get in to a scenario where, with the new data being written into the array and the expansion process going on at the same time the rebuild essentially will never complete. This is especially true with lower end CPU servers and without dedicated RAID cards.
It is dangerous because the rebuild stresses the drive which makes a failure more likely, and a failure during the rebuild process is not great, on top of that you've got a months long ETA...
No fun
