Was the prior drive set in some kind of raid set or just individuals, and what are the old drive capacity vs new?
I guess it depends a lot on what your doing with the server. If it’s pure data store I would just boot off a USB and give yourself all the data space since it’s quite likely all running in ram anyhow.
If you run apps out of it and need the M2 for swap and rapid cache storage the fastest would likely be make a 2 drive zpool, copy a single to it, and repeat as needed until you have it all copied over, then add the 3rd to the zpool
I’ve had similar with other items in the sense of wait several days, no shipping notice so a week later message to cancel it, then several hours later get a ship notice and reply that ‘oh it went out already and you would have to wait to send it back’.
I’m guessing to do with some kind of drop shop inventory nonsense, makes no sense otherwise.
