Well that wasn't it, but it got me doing better Google searches...I have a Realtek rge0 interface... http://opensolaris.org/jive/thread.jspa?messageID=439296 . I wasn't considering the net interface because the problem didn't manifest for me until I turned zfs compression on.
http://sigtar.com/2009/02/12/opensolaris-rtl81118168b-issues/#comment-88 is the driver that seems to have fixed it for most people.

This went fine until I enabled compression on the volume. About halfway through a backup (~250gb done), Solaris loses its network connection with no errors logged (/var/adm/messages and /var/log/* with no entries for an hour preceding). After reformatting the iSCSI volume (from Windows) and starting from scratch to use compression, it takes about 10gb to trigger this. I've tried several switches and routers, and the same always happens - the Solaris system drops off the network for about 15 minutes. I tried to do a 'zfs destroy' on the volume, and it hung, along with all other zfs commands for about 3 hours. The volume only ever contained 550gb total of data. This is a 700gb volume on two mirrored 1tb drives. Looking back through the OpenSolaris-help mailing list, I see the zfs destroy hanging problem, but it looked like people believed that to be more related to dedup. Anyone have any ideas on what I could be doing better to avoid these behaviors? -- This message posted from opensolaris.org <http://opensolaris.org/> _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss -- Tiernan O'Toole blog.lotas-smartman.net www.tiernanotoolephotography.com www.the-hairy-one.com
