Re: [zfs-discuss] questions on zfs send,receive,backups

Well, somehow it's fixed: Since putting in the new Intel card, the transfer from the box dropped so badly, I couldn't even copy a snoop from it. So I removed the dohwchksum line from /etc/system and rebooted. Then just to clean up a bit I disabled the onboard NICs in the bios. Now I'm still seei

I think the better solution is to have two pools, and write a script to change the recording destination time to time, or move the files after it. Like the prototype by Hartz. ps.: Is this a reality show? ;-) -- This message posted from opensolaris.org _
