I am hoping for both of us, that someone here knows even a little > bit. I've done this a few times now... Initially I followed this guide, but still had a few issues. On at least one of my boxes it was nessecary to mark the partition as active which I couldn't do with gpart. IIRC, I used fdisk to "change the active partition" after setting up everything with gpart. Now, for installation... My solution here was that I took a scratch disk and did a minimal install, then pulled the tree and did buildworld / buildkernel (with LOADER_ZFS_SUPPORT="YES"). I then set DESTDIR to the root of the intended zfs system (/data in my case) and did make DESTDIR=/data installworld && make DESTDIR=/data installkernel && make DESTDIR=/data distribution. My memory isn't what it used to be, so I should have documented it for myself once I figured it all out, but I think I'm remembering it all correctly. I have three of my machines running this way, all installed from the same scratch disk with the build on it. All of mine run -CURRENT and I'm not certain how 7.2 differs in this respect. robert. > Thanks, > > Jason > > On Wed, Jul 15, 2009 at 17:12, Jason Garrett <kingedgar_at_gmail.com> wrote: > > > > > > > On Mon, Jul 13, 2009 at 18:09, Drew Tomlinson <drew_at_mykitchentable.net>wrote: > > > >> Jason Garrett wrote: > >> > >>> > >>> > >>> On Mon, Jul 13, 2009 at 13:30, Drew Tomlinson <drew_at_mykitchentable.net<mailto: > >>> drew_at_mykitchentable.net>> wrote: > >>> > >>> Jason Garrett wrote: > >>> > >>> >snip > >>> > >>> I see you tried the zpool import and export, but did you > >>> perform `mkdir /boot/zfs` directly before `zpool export tank > >>> && zpool import tank` ? > >>> > >>> I just have to ask because I did not see that specified, and > >>> you mention not being able to find zpool.cache. /boot/zfs is > >>> where zpool.cache hides out. > >>> > >>> Yes I did.
