(I created this FS few years ago so I can't be 100% sure about the parameters, but I usually only use larger -i NN for big filesystems, and I can guess the exact value examining df -ik). > > > BTW I just noticed that when I use larger values for backup superblock, it reports an error which looks like overflow: > > # fsck_ufs -b 7437746112 /dev/mfid0p1 > Alternate super block location: -1152188480 > ** /dev/mfid0p1 > > CANNOT SEEK BLK: -1152188480 > CONTINUE? [yn] Well, it seems that your beginning of the volume got obliterated. Fsck_ffs cannot convert random sequence of bytes into the valid FFS volume. The only other way to try is to restore content of the cylinder groups which are farther away from the start. Create a scratch volume of the same size, newfs it with the same parameters. Then dd from the broken volume to the new one, with some offset. Offset should be large enough to not include initial superblock, and if the zero cg is damaged, skip it as well. You should use seek=n skip=n (i.e. the same initial offsets both for input and output).
