As I wrote in my previous reply, my pool was unbootable in one machine but boots fine in the other. Both were Intel based amd64 with BIOS, not EFI. I think there are some buggy BIOSes where it cannot boot even on smaller pools than 2TB. (or maybe some improved BIOSes supporting larger boundaries than 2TB? I don't know in what exact position bootloader / kernel was on my 4TB pool) Kind regards Miroslav Lachman
