Recreate all FS structure on the second disk. You can dump al your = FS with something like: >=20 Great. Thanks for that. Have you got a hint as to how I can get access to the root file system? = It's currently set to have a legacy mount point. Which means that when = I import the pool: # zfs import -o readonly=3Don -o altroot=3D/tmp/zfs -f poolname the root filesystem is missing. Then if I try and set the mount point: #zfs set mountpoint=3D/tmp/zfs2 poolname it just sits there; probably because the command is blocking on the R/O = pool, or something. How do I temporarily remount the root filesystem so that I can get = access to the files? Thanks, Joe
