In my case, I wasn't trying to set up gmirror, but just to copy a 500 GB di= sk onto a 2 TB one, because I was running out of space. (The machine is my desktop, incidentally.) I did this backup/restore thing, figured I'd keep the 1st partition, and delete/recreate the others with larger sizes. Maybe that also had something= to do with triggering the bug. I do wonder why I'm not using the occasion to switch to ZFS. Probably becau= se I'm a bit conservative and don't fully trust it yet, LOL. So I get these problems instead! I have other boxes set up with UFS and gmirror and did manage to get them to the point where they'd boot off either drive. Somehow, I didn't end up triggering the bug that time. I wonder why not. Maybe because I didn't try = to delete/recreate any partitions? It reminds me of the interesting time I = had setting up gmirror on a hosted server, where FreeBSD isn't supported, and I= was trying to do it without having to have a KVM put in. I did manage it once, = but only after practicing it on a test box at home first! --=20 You are receiving this mail because: You are the assignee for the bug.=
