Was trying to map out some bad blocks prior to temporarily read/empty 4 =
Tbyte volume using =82badsect(8)=92 - and returing it.
Was expecting to be able to put the sector # into badsect (e.g. =
3432631424 from below FSCK output).
This gave me a bit of an odd:
badsect: 3432631424: Result too large=20
As the daddr_t seems to be a 64bit unsigned; I assumed that the:
number =3D strtol(*argv, NULL, 0);
was some legacy culprint - and changed it to a strtoll as the daddr_t =
you are entering is an int 64.=20
number =3D strtoll(*argv, NULL, 0);
That gets it past that point; only to segv out on:
cg =3D dtog(fs, fsbn);
/usr/include/ufs/ffs/fs.h:#define dtog(fs, d) ((d) / =
(fs)->fs_fpg)
/usr/include/ufs/ffs/fs.h:#define dtogd(fs, d) ((d) % =
(fs)->fs_fpg)
a bit later. While fs is valid - it seems fs->fs_fpg returns as =820=92 =
=97 why is this ? Is geom too new ? Or is badsect too old/retired ?
Dw.
