hello i also suggest, use your 750g drives as raid-1 data pool. i usually use one or better two (raid-1) 2,5 drives in the floppy-bay as system drive gea http://www.napp-it.org/hardware/ -- This message posted from opensolaris.org ___ zfs-discuss

Hi whitetr6, An interesting situation to which there is no, right, answer. In fact, many different answers depending on where you put your priorities. I'm with Frank in keeping data and OS separate. As you've only got two drives, I'd put between 30 to 40 gig as an OS pool on each drive (making

Correct that ... I have seen a bad batch of drives fail in close succession; down to a manufacturing problem. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org

Perhaps an expert could kindly chime in an opinion of making the drives one large zpool (rather than separate hard partitions) and using the various options within ZFS to ensure that there is always disk space available to the operating system (zpool reservation) ... but the more I sit and

I thank each of you for all of your insights. I think if this was a production system I'd abandon the idea of 2 drives and get a more capable system, maybe a 2U box with lots of SAS drives so I could use RAIDZ configurations. But in this case, I think all I can do is try some things until I

I have a 1U server that supports 2 SATA drives in the chassis. I have 2 750 GB SATA drives. When I install opensolaris, I assume it will want to use all or part of one of those drives for the install. That leaves me with the remaining part of disk 1, and all of disk 2. Question is, how do I
