[OpenIndiana-discuss] fuiture small expansion of raidz1 possible?

[Hans J. Albertsson]

I think I just decided to not go too far in saving that last cent... 
(Can't say "dollar" in Europe, but "cent" is as european as raspberry 
pie... :-) ) so I'll buy 3 new disks, split the original mirror to get a 
4th and leave the original other mirror half as extra storage for my 
login/desktop server after migrating the data.
Or maybe even buy a 4th disk outright.

Seagate NAS 5900 rpm disks are reasonably cheap.
