Hi All,
We are thinking about trying out a 2-way or 3-way mirror for a filer based on FreeBSD, with HAST and ZFS.
With traditional ZFS for expanding capacity in what I think of as a traditional 'stripe over mirrors' - it is quite easy by replacing say 500GB disks one at a time with 2TB in a given mirrored unit.
How does this work if we are using hast? Is it transparent? Is it impossible? Is it possible to do and still be 24x7 with a little bit of command line work?
Thanks,
- Mike DeMan
