Hi John, Enjoy your vacation š You are right, in that version of ONTAP 5% was default aggregate snap reserve, but it was already set to 0 at creation š I did find a pair of FAS3270 which I think will take over from the FAS3240, and allow us to add more disks to the aggregatesā¦ Itās not a nice solution, but it is a solution where we do not have to move a lot of data aroundā¦ š /Heino Fra: John Stoffel <[email protected]> Dato: fredag, 5. august 2022 kl. 22.22 Til: Heino Walther <[email protected]> Cc: Wayne McCormick <[email protected]>, Alexander Griesser <[email protected]>, [email protected] <[email protected]> Emne: Re: SV: [EXT] Space issues on older NetApp... >>>>> "Heino" == Heino Walther <[email protected]> writes: What about the aggregate reserve on the destination aggregates?
