FWIW, I bought 9 microSD's and 9 USB controller units for them from NewEgg to replicate the famous ZFS demo video, and I had problems getting them working with OpenSolaris (on VMWare on OSX, in this case). After getting frustrated and thinking about it for a while, I decided to test each MicroSD card and controller independently (using dd) and one of the adapters turned out to be flakey at just writing zeros. It also happened to be the #0 adapter which through me off for a while, since that's where I started. So, then I was still having problems (but I had tested the remaining units), so I went home for the weekend, and left them plugged into their hubs (i-rocks brand seems OK so far), and came back to a system log full of a second adapter dropping out several times over the weekend (though it survived a quick dd). Taking it off the hub, it did the same thing for me if I waited long enough (10 minutes or so - I assume it was getting warmed up). I've also had to replace a server mobo which had a faulty USB implementation (Compaq brand, one of the early USB2.0 chips). Just food for thought - there's a lot to go wrong before ZFS sees it and USB gear isn't always well-made. -Bill ----- Bill McGonigle, Owner Work: 603.448.4440 BFC Computing, LLC Home: 603.448.1668 [EMAIL PROTECTED] Cell: 603.252.2606 http://www.bfccomputing.com/ Page: 603.442.1833 Blog: http://blog.bfccomputing.com/ VCard: http://bfccomputing.com/vcard/bill.vcf _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
