Regarding bitmaps, at one point the source code had a warning about them not being able to be larger than a certain size (for some reason 2^20 bits rings a bell, 128KiB?) or it could cause kernel problems, is that true?
Mostly asking as I'm working/experimenting with a 15-drive RAID array and going to be getting a HyperOS flash-and-battery-backed-RAM solid-state drive from a friend to test storing all the bitmaps on, so throughput will be limited purely by IOPs and the SATA/PCI Express bandwidth to/from the HyperOS.
I wanted to know if there's any gains from having more than 1GB of storage to put all the bitmaps on that you could see if I expect all the drives to be 1.5TB or larger devices w/ newer 4k-sector internal formats? Ditto with the bad-block tables being added soon, figured verifying expected space consumed would be good.
