Hi,
Got a 2-node-switchless pair of 8060's on 9.1-latest. Stacks of 4243 SAS's with IOM3's, so I can't go any farther forward on ONTAP versions yet.
We've got 2 shelves of 224C's looped up but currently unused. At the end of the line, we'd like to get rid of the 4243's and be only on SSD storage.
Seeing as we're going to get to only SSDs, what I'd love to get to is having root-data partitioning, so we don't waste space on the parity tax for the root aggr.
The Aggregate Relocation/ARL guide warns about reusing heads and tells you to wipeconfig. I'm decently comfortable that I can do that and rejoin. But the root-data partitioning information makes it sound so very dire in trying to use root-data partitioning, that you must nuke everything in an HA pair in order to get nodes to switch over to using it.
It would seem to me that, if I ARL all of node1's aggrs over to node2, that node1 can be wipeconfig'ed, booted, be root-data partitioned on the SSDs, and then allowed to come online and join up.
I don't have extra nodes to try this on/swing the data over to, and I can't take a HA-pair outage to 'build them right from the beginning.' And I can't roll forward past 9.1 unless I start using the SSDs as normal disk, because I need to retire all my old shelves.
Does it sound plausible to do this with an ARL+wipeconfig->partitioning, or is this a lurking disaster that I'm just not seeing?
Thanks!
