I have had a pool with imported filesyst= ems from a Solaris system that had dedup activated. Then, when the time cam= e to erase them, it just stalled. When rebooting, it stalled again at mount= ing filesystems, and since then, I=B4ve installed two USB drives to act as = root pool with FreeBSD-9.0-RELEASE so that I could import the original pool= in recovery, but it always stalls after a couple of hours. Looking at top,= I could see that the 16GB RAM was maxed out, so I have heavily tuned down = kmem, arc, etc: vm.kmem_size_max=3D"512M" vm.kmem_size=3D"384M" vfs.zfs.arc_max=3D"256M" And then I tried importing again, but with the same result; RAM reaches 16G= Wired, 0B Free and some swap allocated as well, and then it stalls. So I t= ried updating, so currently it=B4s at FreeBSD 9.1-BETA1 #0: Fri Jul 13 22:3= 6:05 CEST 2012, but still no go, it still stalls when I try importing, even= like: # zpool import -f -F -m pool1 In the link is a screenshot of CTRL+T after it stalled the last time. http://i46.tinypic.com/jhdgrq.png There is about 4TB in there that I really need. Please help, I=B4m out of i= deas, and stupid enough not to have gotten it backed up yet.
