RB> ad2s1f already has 25 gigs of stuff on it. with ounly 14 gigs 'free'. RB> ad4s1f has 25 gigs of stuff on _it_. RB> The 25 gigs of ad4s1f will not fit in the 14 gigs of free space on RB> ad2s1f. It is state after restoration. Before that I do the prestine file system with: newfs /dev/ad2s1f mount /dev/ad2s1f /mnt cd /mnt dump -0Lf - /usr | restore -rf - at the end of restore process I got error about that on target file system there is no inode xxxx. abourt? [yn] I type 'n'. there are about 10 inodes missed. when I compare files it seems that are same on source and target. Is that Ok, may I do not worry about that error messages?
