[OpenIndiana-discuss] extended partions

[Robin Axelsson]

I don't think ZFS is very keen on extended partitions, at least not up 
to version 28 (OSOL b134). I tried once to format a logical partition 
inside an extended partition with ZFS but it didn't even recognize the 
extended partition. After changing it to a primary it was fine. So it is 
likely that also the OI version of ZFS will not like it either.

OSOL/OI don't seem to object to the hard drive having an extended 
partition (it will only see the primaries), so I would recommend using 
extended/logical partitions only with OSes that support it and let OI 
use primary partitions. Since you can have several file systems inside a 
primary partition, each file system can serve as a "logical partition", 
so you can reserve one larger primary partition for OI and subsequent 
data "partitions" if you want.
